Deck Painting & staining serving Boylston and Metro West MA.

A deck's surroundings decide how fast its finish wears. Boylston has a lot of water and woods for its size: the town's 2022 master plan counts surface water at 19% of total area and wetlands at another 10%, with the Wachusett Reservoir the largest feature, and it describes large undisturbed tracts of hardwood and pine forest. A deck under oaks and hemlocks near a wet area dries slowly and collects leaves, pollen and mildew; a deck in an open yard takes direct UV all summer.

Detached single-family houses make up about 85% of the housing stock per the Census, and on those the owner alone picks the product and color. On the 7.6% of units that are single-family attached, check whether shared rules govern railings and deck color.

Shaded, damp decks

Boards that rarely see sun hold moisture, and mildew can grow on and under the finish. Before staining, those decks need a cleaner that kills mildew, a thorough rinse and a brightener to restore the wood's color, then several dry days. A penetrating, semi-transparent stain with a mildewcide additive generally performs better in shade than a thick solid stain, which can trap moisture and peel.

Gaps between boards also matter on these decks. Packed leaves and needles keep the edges wet and lead to rot at the ends of boards and on joists. Clearing the gaps is part of prep, and soft wood found during it gets replaced before any coating.

Decks that lost their shade

Boylston is inside the federal Asian longhorned beetle regulated area, and according to the master plan 35,000 trees in the regulated area were killed by the beetle or felled to contain it. A deck that used to sit under a canopy and now faces open sky can see its old finish gray and break down faster than before. More pigment helps: a semi-solid or solid stain blocks more UV than a clear or lightly tinted product, at the cost of hiding more of the grain.

Near wetlands and streams

More than two-thirds of the town falls under the state Watershed Protection Act, and the local wetlands rules require a permit for development activity within 100 feet of a wetland or 200 feet of a perennial stream. The plan ties that permit to development activity; if a refinishing job turns into enlarging or rebuilding a deck near a resource area, check with the town first, and ask the town directly if you are unsure whether plain refinishing needs anything. Near water it is also sensible to ask what cleaner will be used and how runoff is handled.

Porches, wood types and the order of work

About 56% of Boylston housing was built before 1980, and an older porch floor or railing may carry lead paint under later coats. The lead-safe painting page covers how that changes the scraping and cleanup. The tradeoffs between film and penetrating finishes are laid out in our deck paint vs. stain comparison, and this post on deck stain through a New England winter explains why prep matters as much as the product. If the house is being painted too, the Boylston exterior painting page covers the siding and trim.

• Pressure-treated pine: let new lumber dry until water soaks in rather than beading before the first coat
• Cedar: takes oil-based and semi-transparent stains well; tannin can bleed through pale solid colors without a primer
• Composite: usually cleaned, not coated, unless the maker approves a product
• Painted porch floors on older homes: before scraping, test for lead if the house predates 1978
