' iieductlon oP Moisture Problems at: 1015 U Z.Grand Avenue, Everett, WA v � � Visa6le signs of the problem can be seen throughout the structure. � Signs are present on the south concrete biock �hall and the concrete floor that _ indicate points where moisture is evaporating into the garage area and being � . a6sorbed lnto the building materials. There is exc?ssi�:e :ordens�t�cr, cr� tha standard metal frames of the windows. In the bedroom beneath the larger • - Mindow-there are some floor boards that are Harped. There are stains and mildew on �he exterlor paint along With peeling paint on the West wall . The staining of the paint does not appear to 6e directly related to the moisture producea internally other thart the.condensation draining from the Windows . As with all moisture problems, permanent corrective measures would first eliminate or minimize the moisture at the source of generation. The equipment that has been installed is capabie of handling the moisture that is generated internally based on the difference betWeen the moisture readin9s taken in October of 1989 and March of 1990. Adding 4.96 square foot of net free ventilation to the unheated garage area should minimize moisture build-up related to the moisture that evaporates into the garage area. Ther�nostatic controlled vznts may be out of the question as they cost approximately 3250.00 each. The vents should set up some type of cross ventilation east to west. Thermostatic controlled heat � tape can be applied on the water pipes, under the insulation. The next source to minimize would be the buik water coming into contact with the concrete wall on the south side of the building. It is hard to say hoa much this is contributing to the overall problem. It is the only � visabl2 source of moistura other than what the eccupants generate, excluding _ . any direct leaks from-the .outside. A French drain/groundwatec interceptor - would be an option that should divert any Hater aaay from the concrete. The discharge points of the doHnspout and other ground drains should be verified to determine if they are a contributing factor that aill need to be deait with. � Once ull the sources have been dealt with, the air leakage points �, : �from inside the living space into the structure need to be sealed. This Would include the gaps around plumbing, the space a:ound the bath fa�, kitchen fan and kitchen windoW, etc. The last thing to do would be consulting paint suppliers to determine ' the best approach to a quality job.
