BL exteriors has over 18 years experience working with all types of siding in Gresham Oregon.  
The rain and high winds in Gresham often causes  water to get into areas behind the siding specifically on the south and east sides creating damage and rot lost of insulation and mold .   Lp was used a lot during the building boom in the 90’s and some people still have it.  The wind driven rain seems to especially cause problems with Lp siding, common in Gresham and Troutdale.  Lp siding is a type of  particle board siding that splits apart and grows mold.  We have also often removed and replaced existing vinyl siding that wasn’t installed properly in that the moisture barrier was not flashed good enough to protect the building envelope.   For more information call us at (503) 676-6702 or visit us at  ‎www.beisaslegacy.com we will be happy to help you.
