Before You Sign a Contract: The 15 Technical Questions to Ask a Hardwood Flooring Specialist

Hardwood floors fail for boring reasons: moisture readings not taken, flatness ignored, wrong adhesive, or vague warranty language. The best time to prevent that is before the first plank shows up.

1) What moisture tests will you run, and what numbers are acceptable?

A pro should name the tools and the thresholds: subfloor moisture testing method, wood moisture content checks, and acceptable variance between subfloor and flooring. If the answer is “we’ll eyeball it,” that’s a red flag.

2) How will you verify subfloor flatness, and to what tolerance?

Ask how they measure flatness (long straightedge, laser) and how they will correct it. Pattern floors and wide planks need tighter prep than basic straight lay.

3) What’s the installation method and why is it right for my subfloor?

Nail-down, glue-down, glue-assist, or floating are not interchangeable. The correct method depends on subfloor type (plywood, OSB, concrete), movement expectations, and sound requirements.

4) If glue-down is used, what adhesive chemistry and moisture rating?

You want specifics: silane/MS polymer vs urethane, trowel notch size, spread rate, and moisture mitigation limits. The adhesive choice is often a make-or-break detail over concrete.

5) How will you handle expansion gaps at walls and fixed objects?

Hardwood moves. A good answer includes expansion spacing, transitions at long runs, and how they’ll treat cabinets, islands, and fireplaces so the floor can breathe.

6) What acclimation plan are you using for this home?

“Acclimate 3 days” is not a plan. A plan references site conditions, HVAC operation, indoor RH targets, and what readings must stabilize before installation.

7) What indoor humidity range do you recommend long-term?

In Midwest homes, seasonal swing is real. A specialist should provide a target range and explain how it reduces gapping and cupping over the year.

8) How will you control squeaks and movement?

This is subfloor fastening, adhesive strategy (if used), fastener schedule, and proper underlayment selection. Squeaks come from movement, not “bad luck.”

9) What board selection and grading are you recommending, and why?

Ask how grade affects appearance, knot content, mineral streaking, and how consistent the look will be. Also ask how they’ll blend boxes to avoid color blocking.

10) What milling tolerances are you using, especially for patterns?

Pattern floors need consistent widths and square tongues and grooves. If you’re doing chevron, ask about angle accuracy and matching.

11) How do you plan transitions to tile, stairs, and exterior doors?

Details matter: reducer vs flush transition, stair nosing profile, and how they’ll maintain proper height at doors to avoid binding.

12) What finish system are you specifying, and what does it mean for repairs?

Ask about water-based vs oil-based polyurethane, hardwax oil, or UV-cured factory finish. The “best” finish depends on how you live and how you want to maintain and repair.

13) How will you protect the floor during and after installation?

A professional plan includes breathable floor protection, when furniture can return, and when rugs can be placed without trapping moisture.

14) What is included and excluded in the warranty?

You want to hear specifics: finish wear, installation defects, moisture-related movement, and what homeowner maintenance is required to keep coverage valid.

15) Who is responsible for correcting issues, and what is the process?

Ask about the punch list, the timeline for callbacks, and how disputes are handled. A good contractor has a clear, written path.

If a quote or contract can’t answer these questions in plain language with measurable standards, you’re taking on risk you don’t need. Ridgefield Industries believes hardwood projects should be engineered, not guessed, so you know exactly what you’re paying for and why it works.
