Types of Subfloor Materials

Plywood remains one of the most common subfloor materials, offering excellent strength and durability. We use 3/4-inch tongue-and-groove plywood for residential applications.

Oriented Strand Board (OSB) provides a cost-effective alternative to plywood. This engineered wood product delivers reliable performance and moisture resistance.

Concrete subfloors are standard in basements and ground-level installations. These solid surfaces need proper moisture barriers and leveling before installing finished flooring.

Subfloor Components and Structure

Floor joists form the skeleton of your subfloor system. These horizontal beams typically space 16 or 24 inches apart to support the subflooring material.

The main subfloor layer attaches directly to the joists. Proper fastening prevents movement and squeaking.



Underlayment sits between the subfloor and finished flooring. This layer helps smooth imperfections and provides additional support for your final floor covering.

Importance of Having the Right Subfloor Condition

A damaged subfloor can lead to uneven floors, gaps in your flooring, and squeaky spots when walking. These issues won't resolve themselves without proper repair.

Water damage poses a serious threat to wood-based subfloors. Signs include soft spots, warping, and visible staining.

Regular inspection helps catch problems early. We look for loose fasteners, gaps between panels, and signs of moisture damage during our assessments.

Proper subfloor maintenance extends the life of your finished flooring. Small repairs now can prevent costly replacements later.

Common Subfloor Issues

Professional carpet installation offers many advantages for homeowners. It ensures a perfect fit, extends the life of your carpet, and provides a smoother, more comfortable surface to walk on.

Squeaky Floors

The best way to check for squeaking is to have someone walk on the floor while you listen from below, if possible. Wood-on-wood friction makes distinct squeaking sounds, while loose nails create a popping noise. If you hear a grinding sound, it might mean the subfloor has separated from the joists. We can pinpoint these exact spots and fix them before they get worse.

Before we begin repairs, we test the floor's movement by applying pressure in different spots. Soft or spongy areas need immediate attention. Watch for visible gaps between your baseboards and flooring - this can point to subfloor problems.

A simple test involves placing a marble on your floor. If it rolls on its own, your floor isn't level, which could mean subfloor damage. We use special tools to measure floor slope and identify problem areas that need fixing.

Moisture and Water Damage Impact

Detection and Remediation of Mold

Regular inspections of your subfloor can prevent serious mold problems from developing. You should watch for dark spots, dampness, or unusual smells coming from your floors. If you spot any of these warning signs, call us right away.

We follow a proven six-step process to remove mold from subflooring. First, we contain the affected area to prevent spores from spreading. Then we remove damaged materials and treat the remaining surfaces with EPA-approved products.

Your safety is our top priority during mold remediation. We use professional-grade air filtration equipment and proper protective gear. All affected materials are sealed and disposed of according to local regulations.

Preventative Measures and Maintenance

Regular subfloor maintenance helps prevent costly repairs and extends the life of your flooring system. Good maintenance practices protect against moisture damage, squeaking, and structural issues.
