Compatible Flooring Types After Subfloor Service
Hardwood and Engineered Wood
Hardwood floors need a strong, flat subfloor because they can expand and contract with changes in temperature and humidity. We ensure your subfloor is solid and level to prevent gaps or buckling later.
Engineered wood is more stable than hardwood. It works well over our repaired subfloors because it handles moisture better. This makes it a smart choice if your subfloor had minor moisture issues before repair.
Both types require proper installation, so we prepare the subfloor by leveling and securing it tightly. This helps your wood flooring stay even and reduces squeaks or movement over time.
Tile and Stone Installation
Tiles and stone are rigid and heavy. Even small subfloor movement can cause cracks. That is why we pay close attention to reinforcing and leveling the subfloor before installation.
We use strong materials for repair that support weight and prevent flexing. A solid subfloor reduces the risk of tile popping or grout cracking after installation.
Water resistance is key, especially in kitchens or bathrooms. We prepare your subfloor with moisture sealing so your tile or stone stays secure and damage-free for years.
More Details About Subfloor Repair
What Is Subfloor Repair and Replacement?
The subfloor is the layer beneath your finished flooring. It supports the surface you walk on, such as hardwood, carpet, or tile. Usually, it’s made of plywood or oriented strand board (OSB).
Its job is to provide a smooth, solid base. It also adds strength to the entire floor system and helps with sound and heat insulation. If the subfloor is damaged, the upper floors can warp, creak, or become unsafe. That’s why a strong subfloor is vital to your home’s structure and your floor’s performance.
Subfloor Repair vs. Replacement
Deciding to repair or replace a subfloor depends on the damage extent. Small areas of rot or cracks can often be fixed by patching or replacing just those sections.
When damage covers a large area or the subfloor is severely weakened, full replacement is usually necessary. Replacement ensures a sturdy, even foundation for new flooring. We inspect your subfloor carefully to recommend the best option. Our goal is to restore your floor’s strength while keeping the process efficient and cost-effective.
Subfloor Maintenance Recommendations
Keeping your subfloor in good shape takes attention to key details. Proper care helps avoid costly repairs and keeps your floors solid and safe.
Regular Inspections
We recommend checking your subfloor at least twice a year. Look for signs like soft spots, sagging, or unusual noises when you walk. These usually mean the wood is damaged or weakened. You should also inspect after any water leaks or flooding. Even small amounts of moisture can cause mold or rot under the floor. Using a flashlight and a probe tool can help find hidden damage. If you spot problems early, we can fix them before they get worse.
Moisture Prevention Strategies
Moisture is the biggest enemy of a subfloor. We advise using a moisture barrier when installing flooring, especially in basements or bathrooms. Make sure your home’s humidity stays between 30% and 50%. Use dehumidifiers or proper ventilation if needed.
Check for plumbing leaks and fix them quickly. Standing water near or under your floors must be removed as soon as possible to prevent damage. Proper drainage around the foundation also helps keep moisture levels down under your home.
