Deck Refinishing in Chevy Chase, MD

Old growth fir porch flooring is dense, tight grained and considerably better material than anything sold for the purpose now. It was meant to be painted, and painted is how it survives. A penetrating stain or a clear finish on a tight-laid softwood floor that holds water is a short-lived idea.

What a proper recoat looks like:

• Wash, and then give the floor real drying time. Tongue and groove holds moisture in the joints for far longer than the surface suggests, and a floor that feels dry at the top can still be wet in the seams.
• Take off everything that has lost bond. Feathered edges, not a hard shoulder, or you will see every one of them through the new film in raking light.
• Prime bare wood, including any board end or edge that gets exposed, with a primer made for exterior floors.
• Two finish coats of a porch and floor product built for foot traffic, with honest dry time between them.
• Nobody walks it, nothing gets set on it, and the furniture stays off until it has cured rather than dried. Those are not the same day.

Where individual boards have gone soft, they come out and get replaced in kind. Cutting a single tongue and groove board out of a tight-laid floor without wrecking its neighbors is slow work, and it is worth it, because the rest of the floor is old growth and not replaceable in kind at any reasonable cost.

The column sits on the floor, the floor holds water, and the bottom of the column drinks it. That is the standard failure on a porch of this age, and by the time the paint on the base is blistering the rot underneath is usually well advanced. Base trim comes off and we find out for certain before quoting.

Turned wood columns and boxed columns fail differently. A turned column takes water at the base and can be repairable there if the shaft above is sound. A boxed column is a hollow assembly, so water that gets inside runs down and sits, and the inside is what needs solving before the outside is painted.

Steps are the hardest-working surface on the house: horizontal treads, exposed end grain on the nosings, and every foot that comes to the front door. They want the same porch and floor product as the deck of the porch, real cure time, and usually more frequent maintenance than the floor itself.

The rail is where hand work piles up. Turned balusters, a top and bottom rail with water sitting on the top edge, and a count of pieces that makes a twenty foot rail take longer than a wall. We do the carpentry and wood rot repair ourselves, so replacements are made and primed on all faces and ends before they go in.

Porch ceilings here are usually narrow beadboard, sometimes original, often painted a pale blue by tradition. They are protected from direct weather, so they last, and they are ignored until something on the roof above fails.

When you see staining or peeling on a porch ceiling, the ceiling is the symptom. Water is coming through the porch roof, or the flashing where the porch roof meets the house has failed, or an old copper gutter above is overflowing. Painting the ceiling without sorting out the source is money wasted in a very visible place.

Beadboard itself is hand work: every bead is a groove that has to be cut, and on an original ceiling with paint build the beads may be half filled already. We clean out what we can, prime bare spots the day they are opened, and finish with a product that will hold on an overhead surface that gets condensation on humid mornings.

Where there is a rear deck it is usually a later addition, pressure-treated pine, small, and sitting a few paces from the property line. That closeness decides how we work.

Stripper and cleaner runoff goes somewhere, and on a narrow lot that somewhere is the neighbor's bed, their patio or the storm inlet at the curb. We tarp and pre-wet plantings on both sides of the line, use the mildest chemistry that will actually do the work rather than the strongest thing available, and collect rather than rinse toward the street.

If the old finish on the deck predates 1978, or if the deck is bolted through painted trim on a pre-1978 house, sanding gets treated as a containment job. The federal exterior threshold is more than twenty square feet disturbed, and Maryland is not an EPA-authorized state, so the federal rule applies directly. We contain and collect because the neighbor is close enough to see it, and it is worth asking any company quoting the job how they handle the rule.

The honest question on a hundred-year-old porch floor is how much of the existing film is still bonded. If most of it is sound, a wash, a careful scrape, spot priming and two coats gets you years. If the film is lifting across whole bays, you are patching a floor that will fail again in the same lines, and taking it back is the cheaper answer over any real timeframe.

Fredy gets down on the floor and tests it himself before quoting. Nobody can judge a porch from a photograph, and the two versions of this job are not close in price.

Timing is worth planning. A porch under a mature canopy dries slowly and coats want stable overnight temperatures, so a floor started too late in the fall can still be soft when the first cold snap arrives. We book porch floors for the stretches that can actually cure them. Call 703-869-0593.
