Exterior stain & liquid-rubber membrane
Garage exterior stain & waterproofing
Weathered garage siding and doors in Promontory, restained, with a liquid-applied rubber membrane along the base of the walls, where snow and meltwater sit all winter.
Snow that sits against siding and decks all winter is what wears them out. We restore and protect decks, exterior wood and moisture-prone surfaces with stains, sealers and liquid-applied membranes, scheduled for the dry season before the snow.
Where snow piles up and meltwater keeps returning, we apply liquid membranes such as Liquid Rubber, which cure into one continuous, flexible layer over wood, concrete and metal. On the Promontory garages it runs along the base of the walls and doors, the zone that sits in snow.
Decks, siding, timbers and railings get breathable stains, sealers and protective coatings, matched to the wood species and how hard the surface is exposed.
Every surface needs a different strategy, so we start by looking: what the substrate is, where the moisture comes from, what’s already failing. Then we recommend the prep and the system, and book the work before the first snow.

Exterior restoration & refinishing · June 2026
Exterior restoration and refinishing of the 47,000 sq ft equestrian facility at Promontory Club, covering its architectural wood surfaces, metal components and parts of the stables.
Yes. We restore decks and protect exterior wood with stains and sealers, and use liquid-applied membranes such as Liquid Rubber where snow sits and moisture keeps coming back, as on garages we restored in Promontory. The right system depends on the surface and its exposure, so we start with an inspection.
Yes: siding, exposed timbers, posts, decks and railings. Depending on the wood and its condition, that means cleaning, sanding, removing failed finishes, then staining, sealing and protective coatings. At Promontory we restored and refinished the exterior of a 47,000 sq ft equestrian facility.
