In Portland, OR, Vancouver, WA, and surrounding areas, builder problems, siding damage and dry rot, leaking windows, and water damage to interior window sills, even on new construction, are commonplace when proper waterproofing is not done correctly.  Pacific Exteriors NW has repaired many construction defect issues on large-scale projects and homes simply because of minor aspects missing that were an integral part of the building process and protection of the exterior envelope. Damaged siding, exterior siding problems, window problems, roofing problems, decking issues and rotting trim around windows and doors, water coming into the home, and windows leaking water are all signs of these exterior construction problems.
