Subfloor Preparation for Hardwood Flooring in Rochester Hills, MI
A perfect hardwood floor starts with a perfect subfloor. Our Rochester Hills team levels, repairs, and prepares your subfloor to meet the strict tolerances required for a flawless hardwood installation.
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 assesses and prepares every subfloor before recommending a flooring product, ensuring your investment is protected from day one.
Flatness Assessment
We use a 10-foot straightedge to measure subfloor flatness and identify high and low spots that must be corrected before installation.
Moisture Testing
We test subfloor moisture content with a calibrated meter. Excessive moisture must be addressed before hardwood installation to prevent cupping and warping.
Structural Repairs
Squeaky, bouncy, or damaged subfloor sections are repaired or replaced before new flooring is installed, ensuring a solid, quiet foundation.
Our Process
Subfloor Inspection
We inspect the subfloor for flatness, moisture, structural integrity, squeaks, and any existing damage that could affect the new floor.
Moisture Testing
Subfloor moisture is measured with a calibrated meter. We also test the wood flooring to ensure the moisture differential is within acceptable limits.
Leveling
High spots are ground down with a belt sander. Low spots are filled with floor leveling compound. The goal is flatness within 3/16 inch over 10 feet.
Structural Repairs
Loose subfloor panels are secured with screws. Squeaky areas are addressed. Damaged sections are replaced as needed.
Final Inspection
We re-check flatness and moisture before approving the subfloor for flooring installation. We do not install over a subfloor that does not meet manufacturer specifications.
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.
