What we can help with
Siding Replacement
Tear-off to the sheathing and a complete new wall skin: rot repair, house wrap, flashed windows, a drainage gap where it is required, new trim and new siding.
Siding Repair
Targeted work on part of a wall: rotted boards and trim cut out, torn or missing flashing fixed, storm and ice damage patched, and matching boards woven in.
Fiber Cement (Hardie) Siding
James Hardie and other fiber cement lap, panel and shingle siding, primed or factory-finished, installed to the maker's clearance and fastening rules.
Vinyl Siding
Vinyl lap, board-and-batten and shake-profile siding, and repair of panels that have buckled, cracked, melted or slipped out of their channels.
Cedar Siding
Cedar bevel and lap boards, board-and-batten, and sawn shingles: replacing split or rotted pieces, re-siding in cedar, and keeping the finish ahead of the rain.
Historic Wood Siding Repair
Repairing original lap and shingle siding on older Portland-area houses: consolidating and patching sound boards, milling matches for missing ones, and working lead-safe.
Signs it is time to call someone
Soft, crumbly boards, sills or corner trim
Despite the name, dry rot is fungal decay in wood that stays wet: behind failed caulk, along the tops of trim with no drip cap, and where boards sit close to soil, decks or roofing. Portland averages about 37 inches of rain a year, most of it from November to January, so the same spots stay damp for months.

Grooved plywood panels peeling apart at the bottom
T1-11 is plywood with vertical grooves, and it lets water in through its edges: the bottom cut edge near grade, horizontal joints that lack Z-flashing, and panel corners at windows. The veneers then separate and the panel softens from the edge inward.
Lap boards swollen and mushroomed at the lower edge
Hardboard siding, much of it sold under the Masonite name, and LP Inner-Seal OSB siding are wood-fiber boards that swell once water gets past the paint at edges and nail holes. Both were installed widely in the 1980s and 1990s, and both class-action settlements have long since closed to claims.
Stains or soft wall below a roof corner or window
Siding sheds most rain, and the layers behind it deal with the rest. Water gets past them where a roof edge dies into a wall without a kickout flashing, where house wrap is torn or lapped the wrong way, and where windows were set without head or sill flashing.
Vinyl panels rippled, bowed, cracked or melted
Vinyl moves with temperature, so it is meant to hang loosely on its nails with room to slide at corner posts and J-channel. Panels nailed tight or butted hard into trim buckle when they heat up, and sunlight concentrated by a neighbour's low-emissivity window glass can soften them.
Boards cracked or knocked loose in a winter storm
Portland-area winter storms bring down trees and limbs onto houses: the February 2021 ice storm left about 420,000 PGE customers without power, the largest outage in the utility's history. A broken section of siding exposes the wrap and sheathing behind it, so it needs closing up before the next rain.
Paint peeling off the same boards after every repaint
Paint that fails in the same place is usually being pushed off by moisture from behind, or went on over end grain and replacement boards that were never primed. On a house built before 1978, scraping it counts as disturbing paint that may contain lead.
