Hardwood options we install
Find the right floor for your space, traffic, and budget with our assistance. Installation for homeowners, business owners, and property managers across Massachusetts, New Hampshire, and Maine.
Squeaks, gaps, cupping, and buckling almost always trace back to how a floor was installed, and they tend to appear months later, with the seasons, not on day one.
That's why we treat installation as the floor's foundation, not a cosmetic step. If you're wondering what bad installation looks like, we wrote up the signs of a bad hardwood floor installation.
The Craft
Most installation failures are moisture failures. Before we install, we check:
The wood itself matters too. We use Select & Better Select lumber grades and high-grade fasteners that resist oxidation and breaking. Boards acclimate in your home for several days, so they adjust to your indoor humidity before being fastened down. If moisture readings are too high, we tell you, and we fix the cause before proceeding.
Timelines assume a typical single-room to whole-floor project. Your written scope comes with dates for your home.
We measure, walk the space with you, check the subfloor's condition, and test moisture. You get a fixed estimate after assessment: the price is set before work starts.
The wood arrives early and sits in your home for several days, adjusting to your indoor humidity before it's fastened down, not after. We install only when the subfloor-to-wood moisture difference is within 4%. Why this matters: how long to acclimate hardwood flooring.
Flatness, structure, squeaks, and transitions get corrected while they're still cheap to fix. Underlayment or a moisture barrier goes down where the readings call for it.
Nail-down, glue-down, or floating, depending on the floor and subfloor (see the comparison below). Boards wider than 3¼ inches also get glue, because wider boards move differently.
Prefinished flooring skips this step. We focus on precise fit, clean transitions, and detailing. Site-finished floors are sanded and coated here: water-based coats dry in 1–2 hours, oil-based in 12–15 hours per coat.
We inspect the floor with you (flatness, transitions, sound underfoot) and leave practical care guidance, including the 30–50% indoor humidity range that keeps wood floors stable through New England seasons.
Methods & Cost
The method isn't a preference. It follows from your subfloor and the floor you choose. Here's how we decide.
Over plywood or wood subfloors. The standard for most New England homes. Boards wider than 3¼ in also get glue for stability.
Over approved concrete slabs. Common in condos and buildings on concrete decks. The slab gets moisture-tested before any adhesive goes down.
Over level subfloors, on underlayment. Fastest to install when conditions fit. The underlayment choice does real work here (see what underlayment for hardwood floors).
| Method | Best for | Subfloor | Good to know |
|---|---|---|---|
| Nail-down | Solid hardwood | Plywood or wood subfloors | The standard for most New England homes. Boards wider than 3¼ inches also get glue for stability. |
| Glue-down | Engineered planks | Approved concrete slabs | Common in condos and buildings on concrete decks. The slab gets moisture-tested before any adhesive goes down. |
| Floating | Click-lock systems | Level subfloors, over underlayment | Fastest to install when conditions fit. The underlayment choice does real work here (see what underlayment for hardwood floors). |

Labor is priced per square foot and the wood is priced separately, so you can see exactly where the money goes.
The wood itself is priced by species, grade, and board width in the written scope.
Fixed estimate after assessment. We measure and test the subfloor first, define the scope in writing, then hold the price.
Choosing Your Floor
Both are real wood. The difference is construction, and it decides where each floor can go and how it lives with New England humidity.
One solid piece of wood, usually ¾ in thick. It goes over plywood or wood subfloors, above grade, and can be sanded and refinished multiple times. Expands and contracts more with humidity, so acclimation and the 4% rule matter most here.
A real-wood wear layer over a layered core. It goes over approved concrete and into spaces where solid wood would move too much; the layered core resists cupping and gapping. Refinishing depends on the wear layer: 2 mm or more allows careful sanding.

Crew & Proof
Turnovers and closing dates don't wait for a contractor's schedule. Ours is built for that.
7 crews and 7 fully equipped vans mean we can run several units at once, or slot a single unit between tenants without dragging out the vacancy.
A written scope and fixed estimate per unit keeps pricing consistent across a portfolio. 3 project managers are reachable 7 days a week, and 500+ references are available on request.
Prefinished and engineered floors skip on-site finishing and its cure time. For pre-sale refreshes, refinishing existing floors often beats replacement on both cost and timeline.
Weles runs 7 crews with 7 fully equipped vans across Massachusetts, New Hampshire, and Maine. Hardwood floors are our daily work: installation, refinishing, and repair, nothing else.
The paperwork is part of the service. Before the first board goes down, you know what’s happening, when, and for how much.
Questions about follow-up support? Ask your project manager during the assessment. That conversation is part of the written scope.
Refinishing and installation done with dustless sanding by default, pro-grade equipment, and moisture-controlled standards, managed by dedicated project managers.

Free EstimateHardwood Floor Installation
Unfinished (site-finished) flooring is raw wood that gets sanded and finished in your home. It gives the most control over color and sheen, and the finish seals the seams between boards. Prefinished flooring arrives already sanded and coated at the factory, so the room is walkable as soon as it's installed. We install both; the right choice depends on your timeline and the look you want.
Installation labor with Weles runs $2–6 per square foot, with the wood priced by species and grade in the written scope. HomeAdvisor's 2026 figures put a typical project at $2,500–$6,740 all-in. See Boston-area details.
Plan on one to two weeks end to end: several days of acclimation after delivery, then a few days of installation for a typical area. Site-finished floors add sanding and coating days; prefinished floors are walkable right after install.
Yes: usually engineered hardwood, glued down over an approved slab, or a floating floor over underlayment. The slab gets moisture-tested first, and a moisture barrier goes down where the readings call for it. Solid ¾-inch hardwood generally isn't nailed to concrete.
It follows from the subfloor and the product: solid wood is nailed to plywood; engineered planks are glued to approved concrete; boards wider than 3¼ inches get glue as well, because wider boards move differently. The full comparison: is it better to nail or glue hardwood flooring?
Almost all of these are moisture and prep problems, so we prevent them before installation: moisture readings within the 4% rule, several days of acclimation, subfloor flattening and squeak fixes, moisture barriers where needed, and high-grade fasteners. What failure looks like: signs of a bad hardwood floor installation.
Wood expands and contracts with moisture. Acclimating the boards for several days lets them adjust to your home's humidity before they're fastened down. Installing too early is a common cause of gaps and cupping later. Details: how long to acclimate hardwood flooring.
