How to repair your subfloor yourself

8 November 2023 | Written by Arc Floor

Uneven and damaged subfloors can be a homeowner's nightmare, leading to unstable and unsafe flooring. While DIY subfloor repairs can be rewarding, it's important to understand the potential risks involved. In this blog post, we'll guide you through the steps to repair your subfloor and highlight the dangers of undertaking this task on your own.

Step 1: Assessment

The first step in repairing your subfloor is to assess the extent of the damage. Inspecting your subfloor can be more than a casual walk-through; it's a detailed examination that may reveal hidden hazards. Look for signs of water damage, mold, or structural issues. Keep in mind that uncovering these issues can lead to costly and complex repairs.

Step 2: Gather Your Tools and Materials

To embark on a DIY subfloor repair, you'll need a variety of tools and materials, including:

Safety gear, such as gloves, safety glasses, and a dust mask.

A circular saw or reciprocating saw, which can be extremely dangerous if not used correctly.

A hammer and pry bar, both of which can cause injuries if mishandled.

Screws and a screw gun, which require precision and can lead to accidents.

Replacement subfloor material (plywood or oriented strand board), which can be heavy and challenging to work with.

Construction adhesive, which can be hazardous if it comes into contact with your skin or eyes.

A level and straight edge, which can be sharp and pose a cutting risk.

A chalk line, which can cause eye injuries if used improperly.

Subfloor adhesive, which must be handled with care.

Nails or screws for securing the new subfloor, posing potential injury risks during installation.

This step alone emphasizes the array of tools and materials that carry risks, and it's crucial to exercise caution throughout the process.

Step 3: Remove the Damaged Subfloor

Removing damaged subfloor sections involves using a circular saw or reciprocating saw. These power tools can be extremely dangerous if not handled with care. Mishandling them can result in serious injuries.

Step 4: Inspect and Reinforce the Joists

Inspecting and reinforcing floor joists can be a physically demanding task. Lifting heavy materials and working in tight spaces can lead to strain or injury if not done cautiously.

Step 5: Install Replacement Subfloor Material

Cutting and installing replacement subfloor material can be challenging. Precision is essential, and any errors in cutting or handling the material can lead to uneven surfaces or further damage.

Step 6: Apply Subfloor Adhesive

Applying subfloor adhesive may seem straightforward, but if it comes into contact with your skin or eyes, it can cause harm. Proper protective gear and handling are crucial.

Step 7: Secure the Subfloor

Securing the subfloor with screws or nails can lead to injuries if not done with care. These fasteners must be driven accurately to prevent accidents.

Step 8: Check for Levelness

Checking for levelness might seem harmless, but using a level or straight edge can result in cuts or other injuries if not handled correctly.

Step 9: Prepare for New Flooring

Preparing for new flooring may involve additional hazards, especially when using adhesives and tools for installation.

While DIY subfloor repairs can be a fulfilling project, it's essential to recognize the potential dangers involved and the importance of taking necessary precautions. Additionally, it's important to understand that what may seem like a cost-saving endeavor can actually be more expensive in the long run.

Why Hiring Professionals Can Be More Cost-Effective

Expertise and Efficiency: Professionals have the experience and expertise to complete subfloor repairs efficiently. They can identify issues quickly and execute necessary repairs without delays or errors, ultimately saving you time and money.

Prevention of Costly Mistakes: DIY attempts can lead to mistakes that require further repairs, increasing the overall cost. Professionals are less likely to make such errors.

Access to Tools and Materials: Professionals have access to the right tools and materials at competitive prices, often resulting in cost savings compared to purchasing tools and materials for a one-time DIY project.

Reduced Risk: By hiring professionals, you eliminate the risk of accidents, injuries, or property damage during a DIY subfloor repair, which could result in unexpected expenses.

Warranty and Guarantees: Many professional flooring companies offer warranties and guarantees on their work, providing additional cost protection.

While DIY projects can be rewarding, it's important to weigh the potential dangers and expenses against the cost-effectiveness of hiring professionals.
