Hardwood Floor Installation Flooring Companies

A hardwood floor is the one finish in your house that can outlive the mortgage - solid boards sand and refinish four or five times across half a century. Whether yours does depends less on the wood than on two weeks of process: moisture numbers checked before the first board, the right attachment method for your subfloor, and layout decisions made while the boxes are still stacked.

This page walks the install from delivery day to final coat - what a craft crew does at each step, and what a rushed one skips - so you can judge the work while it is happening, not five winters later.

What a Craft Install Includes That a Fast One Skips

A professional hardwood job is mostly invisible when it is done right: subfloor flatness checked against a straightedge, moisture readings logged for wood and subfloor, expansion gaps hidden under baseboards, boards racked so seams scatter. A fast job skips the measuring and starts nailing - and every failure mode that follows, from squeaks to cupped boards, traces back to that first skipped hour.

Solid vs Engineered: Which Boards Your Home Can Take

Slabs, basements, and why engineered exists

Solid hardwood moves with moisture, which is why it stays above grade and off concrete. Engineered boards - a real wood wear layer over a plywood core - stay dimensionally stable, so they can go over slabs and into basements where solid wood would cup within a year.

Plank width and future refinishes

Wider planks move more and demand tighter moisture control. Wear-layer thickness decides the future: a 4-millimeter engineered face sands once or twice; solid boards sand for generations. Buying the floor is also buying its refinish schedule.

Acclimation: The Week of Waiting That Saves Your Floor

The 2 to 4 percent rule

Crews measure moisture in both the boards and the subfloor with a meter. Install proceeds when the two readings sit within roughly 2 percent of each other for solid wood (up to 4 percent for engineered). Boards installed wetter or drier than the house will shrink or swell toward equilibrium - as gaps or as cupping.

What acclimated actually means

It is not just boxes sitting in a room. Cartons are opened or cross-stacked in the rooms being floored, with the HVAC running at normal living conditions, typically three to five days for solid wood. A crew that delivers and installs the same afternoon is telling you how they handle everything else.

Nail, Glue, or Float: The Three Attachment Methods

Nail-down on wood subfloors

The traditional method: cleats or staples every 6 to 8 inches into plywood. Quiet, permanent, and the default for solid hardwood.

Glue-down on concrete

Engineered boards trowel-glued to a tested slab. Done right it feels the most solid underfoot; done without a slab moisture test it is how adhesives fail wholesale.

Floating engineered planks

Click-locked over a pad, attached to nothing. Fast and forgiving over minor imperfections, with a slightly softer, sometimes hollower feel - underlayment quality decides how much.

Layout Before the First Board

Board direction is decided before the saw comes out: parallel to the longest sightline, ideally perpendicular to joists, and consistent through connected rooms. Then the crew racks the floor - laying out boards from several boxes at once, scattering seams and color variation so the finished field reads random. Stair-step seam patterns and clustered short boards are the signature of a crew that skipped this step.

Site-Finished vs Prefinished: Two Different Projects

Site-finished floors are sanded raw and coated in place: three to five extra days, dust management, and finish fumes, in exchange for a glass-flat monolithic surface and custom stain. Prefinished boards arrive factory-coated with aluminum-oxide finishes tougher than anything applied on site - the trade is micro-beveled edges between boards and touch-up rather than re-coat repairs. Neither is wrong; they are different projects with different install weeks, and your prep plan changes accordingly.

Stairs and the Skill Ceiling

Stairs are hand-fit carpentry: treads scribed to skirt boards, nosings profiled, risers matched. They are billed per step and they are where installer skill is most visible. Ask to see stair photos from real jobs - it is the fastest portfolio check in flooring.

The First 30 Days With a New Wood Floor

Finishes cure for weeks after they dry. Felt pads go under everything, rugs wait two to four weeks on site-finished floors, and indoor humidity stays in the 35 to 55 percent band that keeps boards tight - let it swing hard and cupped or gapped boards are how the floor complains. A forever floor is also a payment plan away for most households - financing options here - and the price question this page deliberately skips is answered with real numbers on the installation-cost page.

When you are ready, have a top-rated hardwood installer measure the rooms and meter the subfloor - the two numbers every good hardwood job starts with.

Top-Rated Flooring Companies

Hardwood rewards the crew that measures twice - these top-rated companies are the ones whose installs get judged years later, not just on walk-away day. Compare them and get your rooms metered.

How to Choose the Right Flooring Company

  • Ask how many days of acclimation they plan and what moisture readings they target - a blank look ends the interview.
  • Have them state the attachment method for your subfloor (nail, glue, or float) and why.
  • Request photos of stair work and board racking in progress, not just finished glamour shots.
  • Confirm the bid states subfloor flatness prep and expansion-gap details in writing.
  • Prefer NWFA-guideline installers whose methods keep the manufacturer warranty intact.

Frequently Asked Questions

How long does hardwood floor installation take?
Plan on one to three days of installation for a typical 500 to 1,000 square feet, after three to five days of acclimation. Site-finished floors add three to five days for sanding, staining, and coats, plus cure time before furniture returns. Prefinished floors are walkable the same evening.
Do hardwood floors really need to acclimate before installation?
Yes - but acclimation means hitting target moisture numbers, not just waiting. Boards and subfloor should read within about 2 percent of each other on a moisture meter, with the house at normal living temperature and humidity. Skipping this is the leading cause of gaps and cupping in year one.
Can hardwood be installed over a concrete slab?
Engineered hardwood can, glued down or floated, after the slab passes a moisture test - calcium chloride or relative-humidity probe. Solid hardwood is a poor fit for concrete unless a plywood subfloor system is built over it first, which adds height and cost.
Which direction should hardwood floors run?
Run boards parallel to the room's longest dimension and dominant sightline, and where possible perpendicular to the floor joists for stiffness. Keep direction consistent through connected spaces; hallways almost always run lengthwise. Diagonal and herringbone layouts are handsome but raise the waste factor and labor.
Is site-finished hardwood better than prefinished?
Site-finished gives a flat, seamless surface, custom stain, and edge-free boards - at the cost of dust, fumes, and extra days. Prefinished factory coatings are harder-wearing and the job finishes faster, but boards carry micro-bevels and repairs mean board swaps. It is a trade-off, not a ranking.
How soon can you walk on newly finished hardwood floors?
With water-based finishes, socks-only traffic is typically fine after 6 to 24 hours and furniture after 3 to 7 days; oil-based finishes roughly double the waits. Rugs come last - two to four weeks - so the finish cures evenly. Prefinished floors skip all of this.
Can hardwood go in kitchens?
Yes, and it is common - kitchens are splash zones, not wet rooms. Wipe standing water promptly, use mats at the sink and dishwasher, and prefer site-finished or well-sealed boards. Full baths and basements are where solid hardwood is genuinely the wrong call.
What subfloor is required for nail-down hardwood?
Typically 3/4-inch plywood or OSB, flat to within about 3/16 inch over 10 feet, dry, and squeak-free. Crews check flatness with a straightedge and moisture with a meter before starting; leveling and re-screwing the subfloor is normal prep work, not an upsell.
