How to Vet a Flooring Installer
Manufacturer certifications, insurance, and the warranty terms that actually matter when something goes wrong.
Flooring installation is one of the trades where the quality of the install matters more than the quality of the product. A premium hardwood installed poorly will fail faster than a midrange floor installed correctly. Vetting the installer matters more than vetting the material.
Credentials worth verifying
NWFA (National Wood Flooring Association) certified installers complete formal training and follow industry standards. Brand-specific certifications (Bona, Coretec, Mohawk Pro) signal the installer can warranty manufacturer-specific issues — not just labor.
Confirm general liability insurance ($1M minimum) and ask whether they carry installer-error coverage specifically. Many cheaper installers only carry property damage, leaving you exposed if their work fails.
Contract terms that matter
Get a written scope including: subfloor moisture test, acclimation period (3-7 days for solid hardwood), specific underlayment product, transition strip handling, and quarter-round/baseboard plan.
Demand a 1-year labor warranty in writing on top of the manufacturer's product warranty. A contractor unwilling to warranty their install for a year doesn't believe in their own work.
