Cleaning, board repair and stain or paint for decks, porches, stairs and railings on Weymouth houses and townhouses.
Single-family detached houses account for 55.5% of the town's housing units, and attached single-family homes for 4.8%. Another 32.7% of units sit in buildings of five or more, where a deck, balcony or porch can fall under association rules rather than the owner's own choice. Knowing which situation you're in comes first, because it decides who picks the color and who pays.
Pressure-treated southern pine is the standard deck lumber, and it has to dry out after installation before it will take stain. Cedar and redwood weather to silver-gray left bare but accept penetrating oils readily. Mahogany and other dense tropical hardwoods resist absorption, so they need thin finishes made for hardwoods or the surface stays tacky. Composite and PVC boards don't need stain at all, only regular cleaning of mildew and pollen.
Before choosing anything, sprinkle water on a few boards. If it disappears into the wood within a minute or so, the surface is ready; if it sits in beads, the lumber is still wet or an old sealer is still working.
North Weymouth sits on a peninsula between the Back River and the Fore River, which flow into Boston Harbor just north of it, and FEMA maps show wave-action VE zones along the Fore River's banks. A deck that looks out over water like that gets direct sun and wind with little shelter, and ultraviolet light is what breaks a stain down.
For decks in that kind of exposure, more pigment means more protection: a semi-transparent or solid stain shields the wood better than a clear sealer or light toner. Clear products look good the first summer, then gray quickly in full sun.
Penetrating stains wear by fading, so the next round is a wash and a fresh coat. Film finishes, meaning solid stain and deck paint, look uniform but can peel on floor boards where water sits and foot traffic is heaviest, and peeling film has to be stripped before you can go back to a penetrating stain. The paint vs. stain comparison sets out the trade-offs, and the winter post on deck stain in New England explains how ice and thaw cycles attack a finish.
A split approach works on many decks: solid color on rails, posts and balusters, which shed water, and a semi-transparent stain on the walking surface.
Decks are on the town building department's list of projects that need a building permit. Cleaning and staining an existing deck is not the same as building one, but work on structure such as joists, posts or stair stringers may cross that line, so ask the inspections office before any repair beyond cosmetic work.
Late spring through early fall gives the most dependable drying weather. For houses by the water, see our North Weymouth page; for the older houses climbing Front Street from the Landing, see Weymouth Landing. If the house itself needs paint, see exterior painting for this town.

Read the master deed and rules first. A deck attached to a unit can be a limited common element, so the association may set the color or handle the maintenance itself. If the association hires the work, it will want the contractor's certificate of insurance on file.
Decks appear on the building department's permit list, which covers building and altering them; staining isn't listed. If repairs touch structure such as posts, joists or stair stringers, ask the inspections office whether a permit applies.
Sometimes, during a dry stretch with mild days and nights. The product needs the surface temperature within its label range and several hours free of rain or heavy dew. Late in the season the boards stay damp longer each morning, which shortens the working day.
Black spots on composite are generally mold or mildew feeding on pollen and debris, not a coating problem. A cleaner made for composite removes them. Sealing usually isn't needed, and some manufacturers advise against it, so check the warranty first.
Floor area is only part of it. Stripping old film, replacing boards, and the number of balusters and stairs take more time than open decking does. Massachusetts market data is on the deck staining cost page, and a free visit gives a written estimate for your deck.
