10 Questions That Separate Good Flooring Contractors from Guys with a Van

If a flooring contractor cannot answer ten basic questions in a 20-minute conversation, do not hire them. The questions below cover licensing, materials, subfloor prep, timeline, and warranty — the five areas where every bad flooring job we get called to rescue went wrong. Use this as your interview script.

We get the rescue calls. A homeowner in Middleton hires the lowest bidder; the floor cups within six months; the original installer stops returning calls; and we walk through to assess. Almost every time, the homeowner says the same thing: "I didn't know what to ask." Here's the real talk about how to hire a flooring contractor in Massachusetts — what to ask, what answer to expect, and what to do when the answer is wrong.

This guide is written for the homeowner doing their first hiring and for the builder qualifying a flooring subcontractor for a new project. Skip the generic "ask for references" checklists; this is the actual interview CabStone would expect to face. If your contractor cannot pass it, they should not pass for you either.

Key Takeaways

• Massachusetts requires a Home Improvement Contractor (HIC) registration for any residential job over $1,000.
• A reputable contractor names their material brands and grades by spec, not by marketing words.
• Subfloor moisture testing should happen before quoting, not on install day.
• Written warranties cover both materials and labor, with separate term lengths.
• A real flooring contractor carries general liability and workers' comp; insurance certificates are pre-issued.
• The cheapest bid usually skips subfloor prep, acclimation, or transitions — three of the most failure-prone steps.

Question 1: Are you HIC-registered in Massachusetts, and Can You Show Me Your Number?

Every residential contractor working on a home improvement project over $1,000 in Massachusetts must register with the Massachusetts Home Improvement Contractor (HIC) Program at the Office of Consumer Affairs. The HIC number is public and can be verified in 30 seconds on the state website.

The right answer: they give you a five- to six-digit number, and the company names it's registered under, and they're comfortable with you looking it up. The wrong answer is any version of "we work under our general contractor's license" or "we don't need one for flooring." Flooring is a home improvement covered by the HIC statute. A contractor who doesn't carry HIC has limited recourse for you under the Massachusetts Home Improvement Contractor Guaranty Fund, which is the whole point of the registration.

Question 2: How Long Have You Been Installing the Specific Material I'm Considering?

A crew with 15 years of carpet experience and one season of hardwood is not a hardwood crew. Material-specific experience matters because the failure modes differ.

Solid hardwood needs acclimation, nail spacing, and finish protocols. Engineered hardwood needs different acclimation and is either glue-down or floating. LVP (luxury vinyl plank, a multi-layer synthetic plank flooring) needs flatness tolerance and underlayment selection. SPC (stone polymer composite, a rigid-core, waterproof plank) requires expansion-gap discipline. Tile needs membrane and mortar selection. None of these skills transfers cleanly. Ask for specific years installing the specific material, then ask for two recent local references for that material.

Question 3: How Do You Test the Subfloor Before Quoting?

This is the question that filters out the bottom 60 percent of bids.

The right answer includes: a moisture meter reading on wood subfloor or a calcium chloride / in-situ RH test on concrete, a flatness check with a 6- or 10-foot straightedge, and a fastener inspection for loose or popped subfloor nails. The contractor should report these numbers in writing as part of the quote. This is where material selection actually matters — a subfloor reading too wet for hardwood may be fine for SPC, and only the test tells you which path is real.

The wrong answer is "we'll check on install day." Subfloor surprises on day one are the number-one source of change orders, and they happen because the contractor never tested.

Question 4: What Specific Brand, Grade, and Wear Layer Are You Installing?

A flooring quote that lists "luxury vinyl plank" with no brand is not a quote. Vinyl ranges from $1.50 per square foot of disposable rental-grade to $7+ of residential SPC with 22-mil wear layer. The difference is enormous and the price often doesn't tell you.

Ask for the brand, the collection name, the wear layer in mils, the core type, and the warranty terms in writing. For hardwood, ask species, grade (clear, select, common), thickness, and finish system. For engineered hardwood, add wear layer thickness and core construction. A contractor who can't spec their own material on paper is a contractor who will substitute a cheaper product if their supplier swaps stock.

Question 5: Who Is Actually On My Job, and Is the Estimator the Installer?

In many small flooring outfits, the person who quotes is not the person who installs. That isn't always a problem, but it should be disclosed.

Ask: will the estimator be on site, will the lead installer be the same person across the whole project, will any work be subcontracted to a separate crew. Get names and roles. Crews change between bid and install all the time, and you have the right to know who is touching your floors. A reputable contractor will introduce the lead installer before day one and stand behind their crew's work even when subcontracted.

Question 6: What Is Your Acclimation Protocol for This Specific Material?

Acclimation is where the line between contractor and "guy with a van" gets very clear.

Solid hardwood in New England usually needs 7 to 14 days of acclimation in the install space, per published NWFA installation guidance — the technical reference that flooring manufacturers cite in their own warranty terms. Engineered hardwood typically needs 48 to 72 hours. LVP and SPC often need 48 hours to reach room temperature, though many manufacturers waive this for short windows. A contractor who waves all of this away — "this product doesn't need to acclimate" — is either guessing or hiding a schedule conflict. Skipped acclimation is the single most common warranty denial in the regional hardwood market.

Question 7: Who Handles Transitions, Trim, and Door Adjustments?

These are the small details that always blow up a job and a budget.

Ask whether the quote includes:

• Transitions between floor types (T-molding, reducers, thresholds) at every doorway.
• Shoe molding or quarter round at the baseboard.
• Door undercut if the new floor is taller than the old.
• Toilet pull-and-reset for bathroom installs.
• Appliance disconnect and reconnect.

A complete quote names a price for each. An incomplete quote uses words like "as needed" and "included," then changes-orders you later. Builders, you want this same breakdown for clean coordination with paint, plumbing, and HVAC.

Question 8: What Is Your Insurance, and Can I See the Certificate?

Two coverages matter for flooring work: general liability ($1 million per occurrence is standard) and workers compensation for any employees on site. The Massachusetts Department of Industrial Accidents requires workers' comp for any employee on a job site — independent investigators do verify coverage in the field.

A reputable contractor has a current Certificate of Insurance (COI) and can email it to you within an hour. They don't get defensive about the question, because every commercial client asks the same thing. If the answer is "I don't need workers comp because I'm a sole proprietor," that's a flag — sole proprietors with helpers still need it, and a 1099 subcontractor on your job is your liability if uninsured.

Question 9: How Long Will the Job Actually Take, and What Slows It Down?

The right answer is a range, not a single number, and it includes contingencies.

A 1,000-square-foot LVP install typically runs 3 to 5 days. A 1,500-square-foot hardwood installation with sanding and finishing takes 7 to 12 days. The contractor should tell you what stretches it: subfloor remediation, weather (humidity affects finish cure), trade coordination, and material delivery delays. A blanket "two days" answer means the contractor is either lying or planning a sloppy job. This is a decision point worth taking time on.

Question 10: What Does Your Warranty Cover, and Who Honors It?

Warranties have two parts: manufacturer (covers material defects) and installer (covers labor and installation errors).

Ask for both in writing. Material warranties range from 5 years (entry-level LVP) to 50 years (high-end hardwood), but they only apply if installation followed the manufacturer's spec — which is why your installer's documentation matters. Labor warranties from local contractors range from 1 year (most common) to lifetime (rare). A contractor who refuses to put labor warranty terms in writing is a contractor who plans to disappear after final payment. We cover warranty parsing in detail in our guide to flooring warranties: what's actually covered, and the upstream piece on decoding flooring quotes — both worth reading alongside this list.

Massachusetts licensing requirements are a separate filter most homeowners skim past. The honest read on what Massachusetts actually requires for license, insurance, and bond is shorter than you'd think — and worth confirming line by line before signing.

Frequently Asked Questions

Should I get more than three bids?

Three is usually enough. The middle bid often wins. Going beyond five bids costs you more time than the savings buy. We tell North Shore clients to interview two contractors thoroughly and add a third only if the first two are very different.

Is it rude to ask for the HIC number directly?

Not at all. The number is public, the registration costs $150, and every legitimate Massachusetts contractor expects this question on the first call.

What if a contractor refuses to test subfloor before bidding?

Get a different bid. Bidding without subfloor knowledge means the contractor is either pricing high to cover unknowns or low to win the job and change-order you. Both outcomes are bad.

Can I trust a contractor who works out of a van?

A truck and a van are equipment, not credentials. We've seen sloppy jobs from companies with showrooms and clean work from one-person crews with a Sprinter. HIC, insurance, references, and material spec are the credentials.

How important are online reviews?

Useful as a signal, not a substitute. Look for reviews that mention specific details — subfloor work, communication, schedule adherence — instead of generic "they did a great job." Reviews from neighborhoods near yours carry the most weight.

Should the cheapest bid always lose?

No, but it should be questioned. If the cheapest bid is more than 25 percent below the middle bid, ask what scope difference explains the gap. Usually it's subfloor work, transitions, or material grade.

Conclusion

Ten questions take 20 minutes. They will save you weeks of rework and tens of thousands of dollars. The contractors worth hiring will welcome the questions. The contractors who duck them are the ones who later become rescue calls for someone else.
