Revere Wood Flooring has sanded, repaired and installed wood flooring in Swampscott for more than twenty years, and out here most jobs open as a question about moisture rather than about style. Cupping across the width of a board, crowning left behind when someone sanded a floor that was still giving up water, board gapping that opens every January and closes by June: each has a different cause and a different fix, and telling them apart is what decides between a screen and recoat, a weave-in repair and outright board replacement.

The housing we work in here runs a wide range. Single-family houses with red oak sitting under wall-to-wall carpet, two-family houses where one floor stays lived in while the other is sanded, and units in the large buildings where the association’s rules on underlayment and rug coverage set the terms long before anybody picks a sheen level.

Every quote we write starts with a moisture meter reading and a measurement of how much wood is left above the tongue, not with a square-foot rate. Stairs are priced by the tread and the riser, never folded into the field number. If a floor has already given up most of its thickness to three or four earlier sandings, we say so before a date is booked rather than after the drum sander is in the house.

What the 2026 Coastal Study Says About Water Reaching Floors

The study and what it found

A coastal resiliency plan led by Kleinfelder, with McAllister Marine Engineering and Woods Hole Group, was presented to Swampscott’s Select Board on September 8, 2026. Kleinfelder projects that by 2030 the town’s highest flood risk area will be about 50 percent dry, particularly around Town Hall and the Fisherman’s Beach coastline. Read as a floor problem rather than a planning one, that is a statement about how often the ground around a building is wet and how long it stays that way.

Engineer Seth Bryant described flood pathways that go pretty deeply into town past Puritan Road and Humphrey Street. A pathway is a route, not a footprint, which is why water occasionally turns up in a room several streets back from the shore while a house closer to the beach stays dry. We do not read a Swampscott address as safe or exposed on distance from the water alone, and we do not guess at where the modeled pathways run beyond the streets the study named.

The same study priced the narrower of the projects the town is weighing: elevating the Fish House three feet, estimated at $2.4 million. The town pursued that smaller-scale work after it did not receive a grant for the larger effort. What an owner takes from all of it is that the wet-season behavior of a floor here is a live question, not a settled one.

What we do when water has already been in

Storm water, surge and a burst supply line all leave wood looking similar and behaving differently, so we trace the water back to where it came in before a single board is pulled. A floor drying under fans while the source is still open is a floor that gets sanded twice, and the second sanding is the one that runs it out of thickness.

We meter the boards and the subfloor on a schedule until the readings settle where they belong, and we photograph and measure the wet rooms for the adjuster while the floor is still wet and the damage still reads in a picture. Owners rarely think of that in the first day of a mess, and it is the part they wish they had later.

Long, repeated damp does something quieter than a flood, and we see it in houses that have never had standing water. Boards take on width through a wet stretch and give it back in the heating season, and after enough cycles the edges compress against each other and the floor develops permanent winter gaps and hollow spots underfoot. That pattern is a fastening and subfloor conversation as much as a finish one, and sanding alone does not resolve it.

Once the numbers hold, the boards sort themselves into three groups. Some flatten out on their own and need nothing but time, some have cupped enough that a flat sand will bring them back, and some have buckled off the fasteners and have to come out and be woven back in with matching stock.

Prewar Houses and What Sits Under the Carpet

Reading the build year before the sander runs

ACS figures put 2,732 of Swampscott’s 6,593 housing units, or 41.4 percent, at 1939 or earlier, which makes a prewar house the ordinary case in this town rather than the exception. Those floors tend to be old-growth pine or early oak in narrower boards, face-nailed or set with cut nails, and more often than not they are hiding under something newer.

We read the build year and the painted surfaces before the sander is switched on, because Massachusetts runs its own lead-safe renovation rules on homes built before 1978 and sanding is precisely the kind of work those rules exist to govern. On a house of this vintage that check happens first, not once the equipment is already unloaded on the sidewalk.

What comes off before anything is cut

Carpet pad, staples, tack strip, linoleum and black mastic all have to leave the boards completely. Adhesive left in place loads an abrasive in a few feet and then burnishes the wood instead of cutting it, and that shows up later as a shiny patch no amount of finish hides. Where old steam radiators and risers were pulled out, we weave in matching boards rather than packing the gap with filler.

The harder conversation is remaining thickness. A pine floor that has been sanded three or four times across a century may have very little left above the tongue, and we measure that before promising a full sand instead of a screen and recoat. An engineered floor gets the same treatment in reverse, with the wear layer measured before anyone says it can be sanded at all.

The damage old floors carry

Houses of this age bring their own list. Pet urine stains that have gone through to the subfloor, black water stains around where a radiator once sat, powderpost beetle holes in old pine and carpenter ant damage near an exterior wall all change the plan, and none of them is visible while carpet is still down.

Parquet, herringbone and chevron all turn up in the older houses here too, and they are sanded differently from a straight-laid floor because the grain runs in more than one direction. We plan the grit sequence around that rather than treating every floor as the same job.

Floors in Swampscott’s Larger Buildings

The building’s rules come first

Of Swampscott’s 4,669 owner households, 449 live in buildings of fifty or more units, and that share of the town changes the work more than the floor itself does. Those buildings set their own terms on underlayment and on how much of a finished floor has to stay covered by rugs, and we book the job against those terms and the condominium bylaws rather than finding out about them on the morning the material arrives.

In an elevator building the schedule is not ours. Material goes up when the freight elevator and the loading dock allow it, sanding happens inside the hours the building permits noise, and the unit below is part of the plan from the start rather than a complaint fielded afterwards.

Newer units are a different animal from the prewar houses a few streets away. Many are prefinished engineered material laid over an underlayment the building specified, and the question there is almost never whether to sand but whether the wear layer will take it at all. We measure it, and where it will not, board replacement in the damaged run is the honest answer.

Two-family houses and units between tenants

Two-unit houses make up a large slice of the stock here, and we run them one floor at a time so the household on the other floor stays in the house while the work goes on. Dustless sanding with a HEPA vacuum matters far more in that arrangement than it does in an empty house, and so does keeping the stairs usable while the job runs.

Vacant rentals are the opposite problem, with a fixed window between one tenant handing back keys and the next signing. We turn those around inside the window, which often means a screen and recoat over a full sand, and a waterborne polyurethane that takes furniture and foot traffic sooner than an oil-modified one will.

Planning a Floor Project in Swampscott

Who answers the town-side questions

The Town of Swampscott Building Department is the office that reviews applications, inspects work and maintains the property records, and questions about what a given project needs on the town’s side belong to them rather than to us. The zoning bylaw also carries a Coastal Flood Area Overlay District, which a 2025 proposal would rename the Floodplain Area Overlay District and align with the state’s model bylaw.

We stay inside what we actually know. What we contribute to that side of a project is documentation: metered readings, dated photographs and measurements of what a floor looked like before the work and after it.

Finishes, color and timing

Massachusetts holds coating content to limits tighter than the federal ones, so the usable finish list here is shorter than a national product catalog suggests. We choose among waterborne polyurethane, oil-modified polyurethane and hardwax oil against those limits, the sheen level you want and how quickly the room has to go back into service.

Stain samples go down on the actual floor rather than on a sample board, because red oak, white oak, maple and old pine each take color differently and a chip in a showroom proves nothing about the boards in your hallway. Where a deeper color is going on, water popping opens the grain so the stain lands evenly across worn traffic lanes and the corners that never saw a shoe.

Stairs get quoted and scheduled on their own. A flight is a set of treads, risers and nosings, each one hand-worked, and a staircase folded into a square-foot number is a staircase somebody is going to lose money on. We price them separately and sequence them so the house keeps a way upstairs while the finish cures.

New material acclimates in the room it is going into, with a moisture meter deciding when it is ready instead of a calendar. Close to the water that wait sometimes runs longer than an owner expects, and the expansion gap at the walls is sized for a house whose humidity swings hard between a heavy August and a dry February.
