Deck Painting & staining across Norwood, Massachusetts.

Census figures count 6,460 single-family detached houses in town, 46.8% of the housing stock, plus 976 single-family attached units such as townhouses. Owners occupy 54.0% of occupied homes. For those owners, the deck, porch and back steps are maintenance items on the same list as the roof and gutters.

A horizontal wood surface takes more punishment than any wall. Snow can sit on it for weeks, rain pools in cupped boards, summer sun bakes it, and chairs and shoes scrape it daily. The finish that lasts is the one matched to the wood and applied to boards that are clean and dry.

Porches on older multi-family houses

Another 19.3% of local housing units are in buildings with two to four units. In South Norwood, the Norwood Historical Society describes rows of triple-deckers built between 1900 and 1920, and where a building of that form has porches on more than one level, each one adds a floor, a railing and a ceiling to finish. Our South Norwood page has more about the area.

Some older porch floors are tongue-and-groove boards under porch and floor enamel rather than stain. Once a floor has been painted, stain cannot soak in, so the choices are to repaint with a floor enamel or strip to bare wood. Porch ceilings, railings and balusters on a house that old may carry decades of paint, and 71.5% of local housing units were built before 1980. On any home built before 1978, paid scraping of those parts calls for the lead-safe methods on our lead-safe painting page.

Know the wood before choosing a product

Each species cleans, absorbs and weathers differently, so identify what the deck is built from before buying anything:

• Pressure-treated pine: new lumber holds a lot of moisture and should dry until water soaks in rather than beading
• Cedar: light and naturally rot-resistant, but soft; high-pressure washing furs the surface
• Ipe and other tropical hardwoods: dense enough that ordinary stains sit on top, so they need an oil made for hardwood
• Painted fir or pine porch flooring: needs scraping, priming of bare spots and a floor-rated enamel
• Composite and PVC: not stained; cleaned following the maker's instructions

Stain, solid stain or paint

Penetrating stains, transparent or semi-transparent, soak into the wood and wear away gradually, so a refresh is mostly cleaning and recoating. Solid stain and paint form a film that hides graying and mismatched boards, but on a walking surface that film can peel where water collects and wear through in traffic paths. Fixing it later means scraping.

A practical split is a penetrating stain on the deck boards with solid stain or paint on rails, posts and skirting, where nobody walks. Our post on how deck stain handles New England winters compares the options.

Prep, drying and the season

A deck in shade or close to the ground dries slowly and grows mildew and algae. Prep starts with a wood cleaner, a low-pressure rinse and, on graying wood, a brightener, followed by enough dry weather for the boards to give up their moisture. Loose nails get reset, split boards replaced and gaps cleared so water drains.

In mid-October, staining still works when the forecast offers several dry days above the product's minimum temperature and the boards are free of dew by late morning. Cold nights slow curing, and once that window closes, cleaning now and staining in spring is a reasonable plan.
