Subfloor Preparation for Hardwood Flooring in Rochester Hills, MI
A perfect hardwood floor starts with a perfect subfloor. We advise on subfloor requirements for every product we carry and connect you with experienced Michigan contractors who level, repair, and prep subfloors to manufacturer specifications.
Why Subfloor Prep Is the Most Important Step in Installation
Hardwood flooring requires a subfloor that is flat to within 3/16 inch over 10 feet, structurally sound, dry, and free of squeaks. Skipping proper subfloor preparation leads to squeaky floors, hollow spots, cupping, and installation failures. Quality Hardwoods of Michigan knows the subfloor requirements for every product we carry — and we refer you to vetted Michigan contractors who assess and prepare subfloors correctly before a single plank goes down.
Product-Specific Requirements
Every flooring product we carry has specific subfloor requirements. We advise you on exactly what your chosen floor needs — flatness tolerance, moisture limits, and approved subfloor types — before installation begins.
Moisture Testing Expertise
Subfloor moisture is the most common cause of hardwood installation failures in Michigan. We explain what moisture levels are acceptable and what remediation is needed before the contractor proceeds.
Vetted Installation Contractors
We connect you with Michigan contractors who check subfloor flatness, test moisture, and make structural repairs before installing — not contractors who skip these steps to save time.
Our Process
Subfloor Requirements Review
We review the subfloor requirements for your chosen flooring product and advise on what the contractor needs to check and correct before installation.
Contractor Referral
We connect you with a vetted Michigan installation contractor who performs thorough subfloor assessment before any flooring goes down.
Flatness & Moisture Testing
The contractor measures subfloor flatness with a 10-foot straightedge and tests moisture content with a calibrated meter. Both must meet manufacturer specifications.
Leveling & Structural Repairs
High spots are ground down. Low spots are filled with leveling compound. Loose panels are secured and squeaky areas are addressed.
Final Approval
The contractor re-checks flatness and moisture before proceeding. No reputable installer puts hardwood over a subfloor that doesn't meet spec — and neither do the contractors we refer.
Frequently Asked Questions
What subfloor is best for hardwood flooring?
3/4-inch plywood is the gold standard subfloor for nail-down hardwood installation. OSB is acceptable if properly fastened. Concrete subfloors require glue-down or floating installation methods and must be tested for moisture.
How flat does a subfloor need to be for hardwood?
Most hardwood manufacturers require the subfloor to be flat within 3/16 inch over a 10-foot span. Some engineered products allow 1/4 inch over 10 feet. We always follow the specific manufacturer's requirements for the product being installed.
Can hardwood be installed over concrete?
Yes — engineered hardwood can be glued or floated over concrete. Solid hardwood can be glued to concrete in some cases. The concrete must be tested for moisture and be at or below grade level. We assess each situation individually.
How do you fix a squeaky subfloor?
Squeaks are caused by movement between the subfloor and joists. We fix them by driving screws through the subfloor into the joists, injecting construction adhesive, or adding blocking between joists where accessible from below.
What is the moisture limit for hardwood flooring installation?
Most solid hardwood manufacturers require subfloor moisture content below 12% and a maximum differential of 4% between the subfloor and the hardwood. Engineered hardwood is more tolerant but still has moisture limits. We test before every installation.
