The structural pests in the Northwest of greatest concern are all dependent on high moisture content in the wood.
If you think about our area of the world, our structural pests all evolved in wet forests. This moisture can come from rain, soil, water supply lines and drains. All these possible sources need to be addressed or there will certainly be a problem. Around here, keep it dry and them pests will usually keep away.
 This is a picture from under a toilet. We checked it before we got in the crawlspace, and noted that it was loose. This nearly always leads to leaks and if not promptly addressed, wood decay. Such leaks are sometimes not so obvious especially if there is insulation and or wall-board installed.
 This is frass or debris and excrement produced by insects. These piles were in regular intervals along the base of the homes exterior wall. After carefully looking at it, we determined that it was not sand and the regular intervals aligned perfectly with the floor joists. I removed some of the insulation that covered the rim on the outside of the building and I found moisture ants, lots of them and extensive damage to the structure. There were about 15 joists visible, and 15 neat piles of frass.
Every single joist we looked at was covered in these pesky pests at this end of the home. We took careful note of this area of the home and proceeded to explore the exterior to determine what were the contributing problems that causes this infestations. Click this picture to see a close up.
 "Most pest species are yellow; they can vary to a rather dark brown, from 3–5 mm long. These are monomorphic species having workers all the same size. Maxillary palpi are long and five-segmented. Colonies usually occur in decayed logs and stumps, but some may be found in soil" WSU Extension Bulletin 1382
 Upon further investigation we noticed that the grade next to the home on this side was sloped the wrong way, trapping water next to the home. The gutters and downspouts were in poor condition, and there was other visible damage on the siding.  The exterior of this home had been neglected for years, having plants touching the structure is several places, deck framing in poor condition, and need of paint and caulk.
Inside the crawlspace we found more frass, and bare earth. All soil under homes should be covered with plastic, there can be up to 15 gallons of water evaporating under the house a day. A vapor barrier will help control the moisture content, keeping it less susceptible to wood destroying organisms.
Treatment for these pests is usually very simple. Eliminate the moisture and repair the damaged wood, pesticides are usually not necessary. Keeping your wood surfaces clean, painted and dry will prevent most common issues.
Never buy a home without a complete wood destroying organism report

Holiday lighting is a wonderful tradition, and these tips will help to keep you and your family safe.
Use care not to overload your circuits. Do not run too many strings together, the amount of lights on string that can safely be connected differs for each type of light. Read and follow the manufacturer's recommendations. Carefully inspect each string for frayed insulation, loose connections or
broken bulbs. Never plug in a string that has bulbs broken open, as the interior
filament is a electrocution hazard. Only use lights outdoors that are approved
for outdoor use.
Use
timers to control your lighting to save more energy. This chart dramatically
contrasts the old style bulbs with modern LED technology lighting using as
little as 1.15% of the energy of the old style lighting.
Another consideration is heat. Never install old style bulbs on a real tree. Think of string of 100, 10 watt lights, that is 1000 watts light and heat. You would never put a 1000 watt heater on a tree for obvious reasons, and these strings are nearly the equivalent of doing just that.  Be careful when hanging lights. Loose wiring is more easily damaged by movement from trees and wind. Never use standard staples, as they can cut into insulation and cause a short or shock hazard. Best to use insulated clips to hang lighting.
 GFCI protected outlets are recommended for all outdoor electrical use. They dramatically reduce the risk of electrical shocks and electrocutions.
Use only UL approved exterior grade power cords outside with proper ground (3 prong connector). Never run cords through doorways, windows where they could get damaged or be a trip hazard. Keep all plugs and connectors off the ground, away from puddles and snow. If you blow fuses or trip breakers, reduce the load on that circuit. Never change the amperage if a blown fuse, if a 15 amp fuse blows, reduce the load on that circuit and replace with the exact same type 15 amp fuse. The wiring in the home is designed to only carry the current of the fuse. That blown fuse likely prevented the wiring from overheating and possible fire. If you see flickering lights, sparks, warm switches, plugs, or outlets, or dimming lights, there is a potential dangerous problem that could cause an electrical fire. As always use extreme care on ladders, make sure they have a good footing and are steady. Never touch your exterior power drop! Any contact with a poorly insulated drop will kill you, an aluminum ladder is an excellent electrical conductor.

With winter on its way a few routine steps will help keep you
safe, comfortable and save you money.
Take care of safety Items first
Check your smoke detectors. If you have an attached garage, live in multi-family, or have gas, oil or wood burning appliances, you must have a carbon monoxide detector!!
All homes should have them, since there is no way to tell if you have a problem with CO. Most people never know they have a problem
until someone is make sick or they are killed.
Take any warning from a carbon monoxide detector very seriously, and call the fire department.
Check your Heat
If you have an oil furnace, have it checked annually. A very small adjustment can make a huge difference in your heating bill, not to mention reducing the pollution from poorly adjusted burners.
Gas furnaces should be checked regularly too. Our recommendations is to have the 1st service at 5 years, again at 10, then every year
thereafter for a mid efficiency furnace. (80% with metal exhaust flues)
Some high efficiency models have shorter live spans (closer to 10 years) so they
need annual checks by 7 years (90% plastic exhaust condensing furnaces) Be sure to keep up on changing your furnace filters. If you have a electric fan forced wall unit (like a
Cadet or a King) be sure to properly clean them. We have a copy of the instructions here.
Chimneys, If you heat with wood, have your flue swept and checked every year. Examine wood stoves for cracked or missing fire bricks, poor door seals, and loose or damaged flue pipes.
 Prepare
the exterior
Clean gutters and check the downspouts assuring that they discharge away from the building, the further the better.
All non frost free hose bibs should be insulated to protect them from freezing. Be sure to disconnect hoses! A hose will cause a frost free hose bib to freeze when the water in the hose freezes.
Look at all trees, and other plants. They should be trimmed back so they cant touch the home. Any contact is a natural path for insects, rodents, and can contribute to structural pests.
Walk around your home and look at the bottom row of siding. Ideally there should be 6 inches of concrete below the bottom row of siding. If soil or bark is piled too high there is a much greater chance of problems with termites ants or beetles damaging the home.
Look at every window and door. Check weather stripping, repair as necessary. Look at every threshold and door sweep, if there are gaps, you will be loosing heat. Caulk all gaps in siding, trim, utility holes, etc.
If it is safe to do so, remove any leaves and other debris from the roof. Use great care to not remove the granules on a
asphalt roof. (DO NOT PRESSURE WASH) Ideally on a dry day, carefully use a leaf blower, debris in valleys and behind chimney's can cause water to back up and cause leaks.
When you are selling your home, you should be prepared for the buyers to have your home inspected. All good inspectors will be looking for how your home had been maintained. Before you list your home, take a close look at these items and you will be better prepared and it may make the difference in a tight market. Make sure there is clear access to all components of the home including electrical panels, water heaters, heating/air conditioners, attics and crawlspaces.
Walk around your homes exterior
1) Roof - Clean roof GENTLY (NO pressure washers, they can ruin a roof!) Carefully using a leaf blower, clean all valleys or other areas. If you use too much force, you will loosen the grit from the roofing and the sun will cause the roofing to shrink and crack.
Clean gutters, repair any loose mounts or leaking joints.
Have professionally swept and/or repair chimney, check masonry, mortar, crowns, bricks/blocks, liners, flashings, rain covers. Check chimney siding, trim, paint, caulk, etc. Have the receipts available for buyers and inspectors.
2) Landscape - Is the soil/mulch touching the homes siding? We would like to see 6" clearance, any less then 3" is too close. Maintain a slope away from the home so water will naturally run off. Never allow water to puddle next to your home. Trim all trees and bushes from touching any of the structure.
3) Drainage - Check every downspout, splash block and drain. Assure that they all direct water away from the home and are not leaking or loose.
4) Repair any loose trim or siding. Caulk all holes, siding, trim, doors and windows. Paint and stain all exterior surfaces.
5) If the driveways are asphalt, they often would benefit from a sealer coat.
Inside the home
1) Heating/AC systems
Have all furnaces, boilers, etc cleaned/serviced and filters changed with receipts for the buyers/inspectors.
2) Safety Equipment
check all smoke detectors, CO detectors, fire extinguishers. Test all GFCIs (they are required within 6 feet of water, outside, in basements and garages.)
Here is a great tip. If you know you need GFCIs and you know how read instructions, then install them! Use care, and never work on live circuits. If an inspector sees a missing gfci, it is likely to cost you $75 or $100 for a "licensed and bonded professional" to install one. If you do it, and you do it correctly, it costs around $15 or less for the part.
3) Lighting and outlets
Repair any broken switches, outlets, covers, fixtures or bulbs.
4) Hardware
Examine every door, lock, hinge, doorstop, casing, and trim. All doors and windows should close and lock easily, repair and adjust as necessary. Weather-stripping should be in good repair. Repair any broken glass, counter balance springs, trim, etc. If the screens are really poor, remove them!
5) Plumbing
Check all toilets, they must be tight and not move when you push them with your knee. The flooring around them should be clean and not have any leaks. Run every sink, and tub look for leaks, sink stoppers, leaking showerheads, enclosures or valves, and loose hardware.
Examine and repair any gaps or cracks in grout and caulk.
Attic - check insulation and ventilation. Assure that no bathroom or other fans exhaust in the attic.
Prepare your home
6) Clean and Paint
Put on your homes best face, clean all floors, carpets, repair any cracks and holes in the drywall and paint. Clean all clutter! Tastefully decorate - properly staged homes are much easier to sell!

With the warmer weather, we are looking to ways to keep our homes cool. Here are some tips to keep your home comfortable.
 Window Coverings
When the temperatures are expected to be high, consider keeping shades closed throughout the day. It is amazing the difference in heat gain when the sun is kept off the windows. I have blinds, thermal shades and exterior sun screens that we use on the hottest days to keep the solar gain to a minimum.
Fans
 I have a digital indoor and outdoor thermometer that I use to determine when the outside temperature has dropped below the inside temperature. When the temperature outside has dropped in the evening, I have a large box fan that is tightly fitted in a back bedroom window that exhausts the hot interior air outside. This causes negative air pressure in the house, and when you open other windows in the home, you will get a nice cool breeze coming in.
Fan Controller
I have built a simple thermostat to control this fan, (See a diagram and instructions here) so when the house temperature drops below 67 or so, the fan turns off automatically. Don't forget to remove the fan, close up the windows and shades in the morning to keep the air as cool as possible during the day.
Wall Air Conditioners
We have also installed ceiling fans to keep the air moving, this helps make it much more comfortable, especially in bedrooms. In my home, I have small room air conditioners that keep an individual room cool. this is especially nice on very hot evenings when you can't cool the house with a fan because the outside air temperature it too high. If you keep the door closed these window units are a great choice.
Home Air Conditioners
 If you have a central air conditioner, there are a few items you should consider to keep it running at peak efficiency.
The outside component of your unit is called the compressor. It houses the pump and the blower that cool the compressed gas that is then pumped into the home to cool the air inside. We see these units covered with landscaping debris (grass, weeds, bushes etc.) all the time.
When this happens the airflow is restricted and it has to work harder to cool your home. Always keep these units clear from obstructions, so they can easily cool the coils. Keep lawn clippings from blowing on them when trimming the grass. Sometimes dryer vents are located too close to AC units, plugging them with lint.
 Read your manual on the best way to clean the unit. Some may be hosed off, ALWAYS TURN OFF THE POWER when cleaning them. Others require more complex cleaning. A dirty AC will waste a lot of energy. When in doubt have a professional clean it regularly, usually at least once a year.
Attic Fans
These will help keep he attic spaces cool. Ideally the attic is the same temperature as the outside air. In the summer, I routinely enter attics that are as high at 145 degrees! Ventilation and insulation are both critical to keep this heat away from your living space. If your attic has less then 12 inches of insulation consider having more added. This will pay for itself in heating in winter and keep you much more comfortable in summer.
Roofing
When re-roofing a home, consider using light colored coverings. They will reduce the heat from the sun. We always recommend silver coating un-coated torch down roofs. It will extend their life and help cool your home.
Thermostats
Use automatic thermostats with timers to control your cooling system. Be sure your air filters are clean, and your ductwork is tight, well insulated and free from leaks. We see leaking ductwork every day!
Landscaping
We recommend that you plant trees that will drop their leaves in winter on the south and west side of homes. This way you have shade in summer and the sun can naturally heat the home in winter. Remember to keep all plants trimmed away from the building.
"To increase the efficiency of your air-conditioning unit by up to 10 percent, plant trees and shrubs to shade the outside unit; place them at least 18 inches away so they don't block the vents on the compressor. For more tips on ways to use landscaping to increase the energy efficiency of your home, see the DOE's landscaping advice." Consumer Reports

The most common source of water under homes is ineffective
downspouts and missing splashblocks or drains. 
Inspect them regularly for failing mounts, crushed downspouts,
and proper drainage. |
Water
in crawlspaces or basements can cause major damage. Many homes have
water problems and the solutions can range significantly in cost to
remedy. You always should start with the simple and cheapest
solutions.
Gutters and
Downspouts
Gutter
mounts failing and the downspout is disconnected. 
Keep downspout drains clear. |
Everyone should walk around their
homes in the worst weather, at least a few times a year and look to
see how the gutters and downspouts are working. Moss, leaves or other
debris can easily clog downspouts and gutters will overflow, possibly
causing damage to roofs, fascia and soffits as well as flooding areas
below grade.
Keep then cleaned and maintained,
make sure all downspouts are discharging away from the building. If
the water puddles next to the foundation, it is likely to end up in
the basement of crawlspace. Make sure mounts are tight and there are
no low spots along gutter runs.
Clean them at least once a year,
usually after the leaves have dropped in fall. Some homes need more
frequent cleaning.
Grading
 If
there is a negative grade (soil sloped to the home) water may puddle
next to the foundation. Where possible, always have soil graded away
from the structure. Consider repairing any concrete walks or patios
that may slope to the home
Be careful with landscaping
edging and planter boxes, as they often will cause water to puddle.
Never allow downspouts to discharge
in low areas like planters, but instead carry water several feet away
from the building.
French Drains
This option is very effective at
capturing water and draining it away before it can work its way under
the home.
This
is one example of a french drain
They can be
expensive, so it is advised that you check the gutters, downspouts,
splashblocks/drains and grading before opting for a french drainage
system
Drains and
Sump Pumps
In some homes where the water
table is high and drainage is poor, you have to deal with the excess
water with drains or pumps. Drains are useful when there is a suitable
location to hookup the pipes to. Often times you are facing a
situation where there is on location low enough to have gravity do the
job, and in these cases a pump is the best answer.
We recommend that you consider a
backup pump in situations where its failure can cause significant
damage or flooding. If there is a power failure or the pump breaks
down, the backup can be very important.
One type of a back up pump is
powered by the water supply to the home. These have the advantage of
mechanically simple, relatively inexpensive and can do the job until
you repair the primary pump or the power is restored. This type of
pump does waste water, so they are not to be used as a primary pump,
only a backup.
See a video on installing a water powered sump pump here.
When the power goes out, you will
be glad you have one!

Always keep small children away from open windows  With
the warm weather we are enjoying it is important to consider the hazards
to children with windows. Every
summer there are a spike of fall injuries of children when we open
windows up to let fresh air in.
Window screens have warnings on then
informing consumers that the they are not to be considered fall safety
devices. Most screens will come dislodged or tear with only moderate
pressure. The view and fresh air are very appealing to young children.
The Consumer Product Safety Commission estimates that there have been
3200 children treated in hospitals and 25 deaths in 2007 from
window falls. These accidents are easy to prevent.  All windows should have safety stops or barriers to
prevent children from falling out of windows. These should be easily
removable by older kids and adults in case of fire. Any window that
opens and children
have access to should be considered a falling hazard. No window that is
accessible to children should open more then 4".
Many
parents make the faulty assumption that a window screen will prevent
this kind of accident. Where
a window can be opened from the top and bottom, always open only the
top. It is much safer to open the top of a double hung window. Never keep furniture near a window that a child can climb on and gain access to a window.

We use laundry equipment everyday with out a lot of thought to the potential hazards they may pose. According the Consumer Product Safety Commission washers and dryers are responsible for more then
$230,000,000 worth of property damage a year in the US alone. Most of the common problems at the root of these statistics are easy to address.
Power Cords
We found this dryer power cord on an inspection, notice it does not have a proper strain relief connector.
As with all power cords be careful when you use the plugs, but ESPECIALLY with large 240 volt connections. The plugs are large and require a bit of effort to insert, making it necessary to wrap your hand around the plug and it is easy to accidentally touch the conductors when inserting or removing them. This same advice applies to all large sockets like electric ranges, RV plugs, large tools etc.
Metal braided hoses are much more resistant to bursting.
Plugged vents and hoses are a fire hazard.
This hot water heater has exhaust rollout. Improper flue design or inadequate air supply can cause combustion gasses to vent into the home. If your heater has these stains please have it checked out.
|
Dryers use a lot of power, and usually do not come with their power cords installed when you buy them. When hooking up a power cord, follow the manufacturers instructions, and be sure to have the proper strain relief fitting. Since dryers vibrate and can have sharp edges to the sheet metal enclosures, cords can short out, causing a potential fire or electrocution hazard.
Washing machine hoses
These hoses are under pressure all the time and can burst causing extensive water damage to the home. Since washers will jiggle when they operate the hoses can rub against the wall behind them. We always recommend the metal braided hoses for washers since they are much more burst resistant and less likely to be damaged by the movement of the appliance. Leave at least 4 inches of space behind the washer to prevent hoses from kinking or chafing and inspect them regularly. If you see any bulges, rust or any other damage, replace them right away.
Dryer vents and lint build up
It is recommended that you check and clean the dryer venting regularly. Use flexible metal pipe, not the foil or vinyl accordion type hoses, they are more likely to catch lint and have an increased risk of fire.
Read an article on cleaning dryer vents here.
Smoke detectors are important in laundry areas, since fires associated with dryers cause more then $80 million of damage a year. Be sure that dryers are properly vented outside and not leaking inside the home, attic or crawlspace as this moisture is a conducive condition for structural pests. If there is significant lint buildup inside, your dryer vent is likely leaking.
Fresh air/back drafting
When dryers run they exhaust a lot of air outside the home. This can produce a negative air pressure condition leading to a possible back-drafting of combustion gasses from furnaces, hot water heaters etc. This problem is especially true in modern energy efficient homes or confined spaces such as a closet. All homes with combustion appliances must have carbon monoxide detectors!
Read more about back-drafting hazards here.
GFCIs
Then properly installed, GFCIs prevent two thirds of all serious electric shocks a year. All outlets with in 6 feet of water, (laundry, kitchens and bathrooms) in garages or outside should have GFCIs. They are cheap and easy to install and might save your life.
Read how install them here.
Explosion hazards
Both washers and dryers have electric motors and other components that can produce sparks capable of igniting flammable vapors or gasses. Laundry equipment are sometimes in garages where there may be gasoline, paint, solvents, propane etc. Always store these chemicals in their original, properly labeled air tight containers. If there is a spill, DO NOT use any electrical appliance or garage door openers until it is cleaned up and all vapors have dissipated.

Fan forced furnaces:
If your home is equipped with a fan forced furnace, have the fan running continuously. This will draw air through the filters capturing harmful pollutants. 
Keep the filters clean, replacing them every 60 to 90 days. High efficiency air filters will capture up to 30 time more pollutants then standard filters. The spun organic/fiberglass filters are the poorest choice, so avoid the reusable washable types. If you do not have a fan forced furnace, you might consider using a portable air cleaner. The units have a huge range in costs and effectiveness, read more about 
keeping crawlspace moisture low. Beside health issues, excessive moisture in crawlspaces is a conducive condition to wood destroying organisms. If you have combustion appliances, check the air intake vents to assure they are not clogged. Hot water heaters, furnaces, gas stoves etc are possible sources of carbon monoxide without a good supply of fresh air. The American Lung Association recommends annual service of all combustion appliances. At a minimum install
