# LI Flooring Co.: Long Island's Full-Service Flooring Company
My grandfather started laying floors in Nassau County in 1958. My father took over the business in 1987, added Suffolk territory, and built the refinishing side of the shop. I came on full-time in 2011, and for the past fifteen years I've been running installations, training our crews, and doing most of the in-home estimates myself. Three generations, one trade, one geography.
That history isn't a marketing line. It means our crews know which Levittown subfloors run consistently out-of-plane, which Smithtown neighborhoods get the worst humidity swings, and why that 1960s parquet in your Merrick Colonial looks the way it does. We work exclusively on Long Island, for Long Island homeowners, with installers we hired and trained ourselves.
We serve all of Nassau County and all of Suffolk County — from Valley Stream to Montauk, from Port Washington to Patchogue. If you're looking for a flooring company on Long Island that can do everything under one roof and stand behind the work, this is us.
## What to look for in a Long Island flooring company
Not every contractor who shows up with a truck and a sample board is a legitimate flooring company. Long Island homeowners pay a premium for licensed, insured, credentialed work — and they should. Here's what separates a real flooring company from a cash-handshake crew:
Nassau/Suffolk Home Improvement Contractor (HIC) license. Required by New York State for any residential improvement job over $200. Ask for the number and look it up. No license means no recourse if the work fails.
NWFA certification. The National Wood Flooring Association certifies installers and finishers who have demonstrated hands-on competency in hardwood installation, sanding, and finishing. It's the industry's clearest credential for wood-specific work.
Dustless refinishing equipment. Any company refinishing floors in an occupied or recently occupied home should use contained sanding systems — typically a Lägler HUMMEL or equivalent with a vacuum-coupled shroud — that capture 99%+ of sanding dust at the source. Open sanding spreads fine particulate through your HVAC for weeks.
On-staff installers, not subs. Many flooring "companies" are actually one salesperson and a Rolodex of day-labor subcontractors. Ask directly: are your installers W-2 employees? Ours are. It matters for quality consistency and for warranty accountability.
10-year workmanship warranty. Materials are covered by manufacturer warranties. Workmanship — the installation itself — should be warranted by the company separately. We offer 10 years on installation labor. A company offering 1 year is telling you something about their confidence.
LI Flooring Co. holds an active Nassau County HIC license, carries NWFA-certified installers on staff, runs Lägler dustless sanding equipment on every refinish job, employs all our installers as W-2 workers, and backs every job with a 10-year workmanship warranty.
## Our full service list
We're a full-service flooring company, not a niche shop. One call handles the entire floor:
Solid hardwood installation. Red oak, white oak, maple, walnut, hickory — nail-down, glue-down, or float depending on your subfloor situation. Custom stain and finish to match existing floors or match your trim.
Engineered hardwood installation. Wider plank, greater dimensional stability over radiant heat or concrete slabs. Same species and finish options as solid.
Luxury vinyl plank (LVP) installation. Waterproof core products for kitchens, baths, basements, and rental properties. We carry 20-mil commercial wear layer options that outlast most solid hardwood in high-traffic applications.
Tile installation. Porcelain, ceramic, and natural stone for floors and foyers. Large-format (24x48) installation using leveling systems and epoxy grout.
Carpet installation. Bedrooms, stairs, and finished basements. We carry residential and commercial grades with proper tack strip and power-stretch installation.
Floor refinishing. Sand, stain, and recoat of existing hardwood using our dustless Lägler system. Oil-based, waterborne, or hard-wax oil finishes available.
Subfloor repair. Squeaks, soft spots, out-of-plane sections, water damage, rotted plywood. We fix it before we floor it — not after.
## Why a real Long Island flooring company beats big-box installation
Home Depot and Lowe's offer installed flooring. The installed price sometimes looks comparable to what a local company quotes. It rarely is, and the gap becomes obvious after the job.
The core issue: big-box installation contracts are fulfilled by third-party labor brokers. The company that shows up to do your floor is not a Home Depot employee, is not trained by Home Depot, and is not accountable to Home Depot for workmanship. If something goes wrong, you're navigating between the retailer's customer service and the broker's customer service — and the warranty responsibility falls into the gap between them.
A local Long Island flooring company that does its own installation has one throat to grab. If the floor fails, we come back. No broker chain.
There are also practical advantages a local company provides that big-box retail cannot:
- Local product knowledge. We know which LVP products hold up to Long Island basement humidity cycles and which ones delaminate in year two. Retail floor staff rotate monthly and sell whatever is in stock.
- Permit coordination. Most Long Island towns require a permit for flooring work over $3,000. We handle the permit, schedule the inspection, and keep the paperwork. Big-box contracts usually exclude permit costs entirely.
- Subfloor reality. Long Island housing stock is old. Subfloors in postwar Capes and colonials almost always need work. A big-box installer will refuse to proceed if the subfloor isn't perfect (or charge surprise fees); we scope the subfloor prep into the estimate upfront.
Here's a direct cost comparison by material, showing what each option actually delivers:
| Material | LI Flooring Co. (installed) | Big-Box Install (advertised) | What Big-Box excludes |
|---|---|---|---|
| LVP (premium 20-mil) | $8–12/sq ft | $6–9/sq ft | Subfloor prep, haul-away, permit |
| Engineered hardwood | $11–16/sq ft | $9–14/sq ft | Subfloor leveling, permit, disposal |
| Solid hardwood | $12–18/sq ft | $10–15/sq ft | Subfloor repair, acclimation time, permit |
| Refinish (sand/stain/finish) | $3.50–6/sq ft | Not offered | — |
| Tile (porcelain) | $12–20/sq ft | $11–18/sq ft | Cement board, leveling, permit |
The exclusions close most of the gap. The warranty gap never closes.

## We're a Long Island hardwood floor company specifically
Hardwood is where our family's history lives. My grandfather hand-sanded floors with belt sanders before dustless systems existed. My father trained under NWFA-certified finishers at a time when waterborne finishes were considered experimental. I'm the third generation to sand, stain, and finish floors on Long Island.
That matters because hardwood is the most skill-dependent category in residential flooring. LVP and tile have reasonable tolerance for installer error. Hardwood does not. A solid hardwood nail-down job on an old subfloor requires correct acclimation time (minimum 5 days in-room for solid hardwood), moisture testing at both the subfloor and the wood bundle, proper nail pattern for the species and thickness, and a finishing process that accounts for the grain and existing stain color.
Our NWFA-certified installers run moisture meters on every delivery, acclimate product per species spec, and document the readings. Our finishing crews use Lägler HUMMEL dustless sanding equipment — the professional standard — rather than consumer drum sanders that can dish or chatter an old floor.
We also do custom stain work: matching to existing wood in another room, matching to a kitchen cabinet color, or creating entirely new finish profiles using specialty stains layered before topcoat. This is finisher craft, not production work.
For Nassau County hardwood projects specifically — where town permit rules, postwar subfloor conditions, and climate acclimation requirements all factor in — see our hardwood floor installation Nassau County guide.

## Frequently asked questions about Long Island flooring companies
Does a Long Island flooring company need to be licensed?
Yes. New York State requires any contractor performing home improvement work over $200 to hold a Home Improvement Contractor license issued by the county where the work is performed. Nassau County and Suffolk County each issue their own HIC licenses. Before signing any flooring contract, ask for the license number and verify it at the county's contractor lookup portal. An unlicensed contractor cannot legally pull a permit, and their work won't pass a home inspection at resale.
What warranty should a flooring company offer on Long Island?
Manufacturer warranties cover material defects and are independent of your installer. What matters is the installer's own workmanship warranty — the guarantee that covers how the floor was installed. A credible Long Island flooring company should offer at minimum 2 years on workmanship; the better shops offer 5 to 10. We warranty our installation labor for 10 years. Any company that doesn't provide a written workmanship warranty, separate from the product warranty, is a risk.
Should I choose hardwood or LVP for my Long Island home?
The honest answer depends on where the floor is going and what's underneath it. In basements, bathrooms, or kitchens — anywhere you could get standing water — waterproof LVP core products are the better choice, and no hardwood company that's being straight with you will tell you otherwise. On above-grade main floors with a solid plywood subfloor, solid hardwood is still the premium choice for resale value, refinishability, and lifespan. A good Long Island hardwood floor company will tell you when hardwood is wrong for a room and recommend LVP instead. We do this routinely.
Can you refinish my existing hardwood floors, or do they need to be replaced?
Most Long Island hardwood floors from the 1950s through 1980s are 3/4" solid strip or plank, which means they have a wear layer of 1/4" or more above the tongue — enough for 4 to 8 additional sand cycles over their lifetime. In many cases, refinishing costs one-third what replacement costs and looks identical to new when done correctly. We measure wear layer depth at the estimate visit. If the floor can be saved, we'll tell you so. If it's cupped from moisture damage or thinned past safe sanding depth, we'll explain why replacement makes more sense.
Do Long Island flooring companies handle permits?
Licensed flooring companies in Nassau and Suffolk County can and should pull permits for qualifying jobs. Most Long Island towns require a building permit for flooring work exceeding $3,000 in project value. We include permit coordination in our contracts. If a contractor tells you "don't worry about the permit" or quotes you without mentioning it, that's a warning sign — unpermitted work shows up at the worst possible time during home sales and refinances.
