SUPERIOR EXTERIOR SYSTEMS has inspected thousands of homes over the years right here in the entire Portland and Vancouver Wa metro areas. If you don't know if you have Lp siding (Louisiana Pacific), Eifs stucco, Masonite Omniwood, Wherehauser or any other oriented strand board style siding, we can help you. As a professional siding contractor, we use high end moisture meters that can help determine if you have a problem.

Local home builders in the 80's & early 90's usually used the infamous Lp siding which ended up going into a class action lawsuit in the mid 90's. Unfortunately these sub-standard builders would also install Lp sub wall UNDERNEATH the actual siding instead of using REAL plywood underneath. The reason is most builders would generally order from the same lumber yard in 1 delivery to cut down on expenses. Lp panel style 4x8 sheets is ALWAYS installed directly over the studs with NO moisture barrier to protect the studs which is absolutely ridiculous although it met weak building codes.

Eifs is an artificial stucco builders from California would often use and stands for Exterior Insulated Finish System. (For more specific info and photos of EIFS click on the EIFS-Stucco link above) EIFS stucco is often used on high end homes. The problems comes when ANY amount of rain gets trapped behind the stucco veneer surface. This causes mold on the sub wall in that the moisture can't drain out and is slow to evaporate simply because it is so damp in our climate. The rot & mold we have found under EIFS stucco homes here in Portland PDX - Vancouver Wa metro is considerably more than Lp although there is definitely more Lp than EIFS stucco here in town.

No matter what type of siding you have, we can help you so give us a call.
