What Causes Subfloor Damage in Florida?

The #1 Culprit: Moisture.

Most mobile home subfloors are made of oriented strand board (OSB) or particleboard, which are extremely susceptible to moisture damage. Any breach in your vapor barrier allows moisture to be absorbed by the subfloor, causing it to swell, rot, and weaken from the bottom up.

Other Causes

Damage can also result from slow plumbing leaks, spills, or termite damage.

The Connection Between Your Vapor Barrier and Subfloor

You cannot properly fix a subfloor problem without addressing the vapor barrier. A soft subfloor is almost always the symptom; a damaged vapor barrier is the disease.

Replacing a section of rotted subfloor without fixing the underlying moisture source is a temporary fix that is likely to fail. The new wood will absorb the same moisture, and the problem will return. For a lasting repair, we highly recommend a two-part approach: first, we eliminate the moisture source by repairing or replacing the vapor barrier. Only then do we replace the damaged subfloor.

Our Subfloor Repair & Replacement Process

In-Depth Inspection: We perform a thorough inspection from underneath the home to identify the extent of the damage and the source of the moisture.

Precise Removal: We remove the finished flooring and cut out all sections of the damaged subfloor, exposing the floor joists.

Joist Repair: We inspect the underlying floor joists for rot. If any are compromised, we repair or replace them to ensure a solid base.

Installation of High-Quality Subfloor: We install new, high-grade, moisture-resistant subfloor panels designed to perform better in Florida's high-humidity environment.

Foundation Check: During the repair, we ensure the home is properly supported and level to prevent stress on the new materials.

Subfloor Repair Frequently Asked Questions

Can you install new flooring over a damaged subfloor?
No. Laying new flooring over a weak subfloor will fail. The new flooring will not sit correctly and will quickly show signs of damage. The subfloor must be solid first.
What materials do you use for subfloor replacement?
We use high-quality, moisture-resistant products, which are far superior to the original particleboard in many older homes.
How long does subfloor replacement take?
The timeline depends on the size of the area being replaced. We will provide a clear project timeline with your free estimate.
