Flooring failures — gapping hardwood, cracking tile grout, LVP that separates at joints, a floor that squeaks throughout — are among the most disruptive home improvement problems because they affect the entire living space and are expensive to remediate. Here’s what to do when you discover the work wasn’t done correctly.

“The homeowners who have the best outcomes after a failed flooring installation are the ones who documented the installation conditions at the time — moisture readings, subfloor flatness measurements, photos of the subfloor before it was covered. Without that documentation, the contractor can always claim the subfloor was the problem, not the installation. With it, you have a clear record of what conditions were present when the floor went down.”

— Finlay Morrison, certified flooring specialist and product consultant with 13 years of experience in residential flooring sales and installation across the Toronto and Hamilton areas

Step 1: Document the Problem Thoroughly

Before contacting anyone, document the failure comprehensively:

  • Photograph the problem from multiple angles — gaps in hardwood, cracked grout lines, lifted LVP edges, squeaking locations mapped on a floor plan
  • Note when the problem appeared and what conditions may have preceded it (a particularly dry winter, a wet basement event, the first summer after installation)
  • Gather all records from the installation — the original quote, contract, invoice, any warranty documentation, and any notes you made about installation conditions
  • If you have moisture or flatness readings from the installation, locate them — this documentation is invaluable

Step 2: Identify Whether This Is a Product Failure or an Installation Failure

This distinction matters for who you pursue for remedy:

Product failure (e.g., a manufacturing defect in the wear layer, premature delamination of the core) → Manufacturer warranty claim

Installation failure (e.g., gapping from inadequate moisture management, cracked grout from insufficient backer board, squeaking from inadequate fastening) → Contractor warranty claim

In practice, the line between these is sometimes disputed. An independent assessment by a flooring consultant or inspector can objectively establish the cause.

Step 3: Contact the Flooring Contractor in Writing

Notify the contractor by email, describing:

  • The specific failure (be precise — “hardwood gapping up to 4mm at joints throughout the living room”)
  • When you first noticed it
  • Your belief that it falls within the installation warranty
  • Your request for an inspection and remediation

Give them 5–10 business days to respond. Keep all records of communications.

Step 4: Get an Independent Assessment

For any significant flooring failure, hire an independent flooring inspector or building consultant. Their written assessment identifying the cause of failure — whether it was an installation error, a product defect, or a pre-existing condition — is the objective evidence that makes every subsequent step possible.

Independent flooring consultants are available through the World Floor Covering Association and similar industry bodies. The cost of an independent inspection ($200–$500) is almost always worth it on a floor that cost $10,000–$30,000 to install.

Step 5: Manufacturer Warranty Claim (for Product Failures)

If the independent assessment identifies a product defect, contact the manufacturer directly with:
– Proof of purchase
– The installation date and contractor information
– Documentation of the failure (photos)
– The independent assessment report

Most manufacturers have a warranty claims process on their website.

Step 6: File Complaints

Your local consumer protection office (consumerprotectionontario.Ca): For unfair business practices or failure to honor warranty obligations.

Better Business Bureau: Creates a public record of your complaint.

World Floor Covering Association: If the contractor is a member, a complaint can be filed through the association.

Step 7: Small Claims Court

For unresolved financial disputes within the regional limit (up to $35,000 in many regions), small claims court is an option. You’ll need the original contract, the warranty document, the independent assessment report, and evidence of the remediation cost. The cost of a professional installation to correct the failed floor is typically the damages claimed.
