Common Subfloor Issues

Spotting typical subfloor problems early is important to fix them quickly, which can save a lot on repairs and stop major harm.

Water Damage

Water damage can be insidious, often presenting as mold growth and structural weakness, affecting both plywood and concrete subfloors alike.

To assess potential water damage, start by checking for dark spots or warped flooring.

Use a moisture meter, such as the Wagner MMC220 ($129), to check moisture levels in both types of subfloors. If readings go above 18%, you should look into it more.

Preventive measures include:

• Installing a sump pump in vulnerable areas
• Applying waterproofing sealants
• Ensuring proper drainage around your home

Regular inspections, especially after heavy rains or snow melt, can help catch issues before they escalate.

Pest Infestation

Issues with pests, such as termites or beetles that damage wood, can badly affect subfloors. Regular inspections and treatments are necessary.

To identify a pest infestation, look for specific signs like mud tubes on walls, discarded wings, or hollow-sounding wood.

Regular check-ups every six months can catch issues early. If you see these signs or think you have a pest problem, it’s important to get in touch with a company like Terminix.

Their initial treatment averages around $250 and includes a thorough inspection, extermination strategies, and preventative measures to safeguard your home.

Being proactive in pest management can save you costly repairs down the line.

Rotting Wood

Rotting wood in subfloors typically results from prolonged moisture exposure, leading to compromised structural integrity and potential safety hazards.

To identify rotting wood, look for discoloration, soft spots, or a musty odor. Common causes include leaky plumbing, inadequate ventilation, or external water sources.

Once you’ve determined the extent of the damage, you can choose between patching or replacing the wood.

1. For a DIY patch using plywood, expect to spend around $25 per sheet; cut out the rotted area, fit the new piece, and secure it with screws.
2. Sometimes, you may need to completely replace the floorboards, and this can lead to extra expenses for both the work needed and the supplies.

Uneven Flooring

Uneven flooring is often a sign of underlying subfloor issues, which can stem from improper installation or damage over time.

To assess the problem, begin by using a long level or straight edge, measuring across various sections of the floor. Identify areas that deviate significantly from a level plane.

For leveling, consider using self-leveling compound, which costs about $30 for a 50lb bag. Begin by ensuring the subfloor is both clean and dry. Next, prepare the compound as directed by the manufacturer.

Pour it into the low spots and let it spread naturally, creating a smooth surface. This method effectively resolves minor height differences, restoring your floor’s evenness.

Creaking or Squeaking Sounds

Noises like creaks or squeaks in your house usually mean there are loose or broken joists in the subfloor that need immediate repair.

To address these issues, begin by reinforcing loose joists with 3-inch deck screws, which can be found in most hardware stores for about $10 for a box.

Applying a lubricant solution, such as silicone spray, to the affected areas can reduce friction and noise.

If you need to replace any damaged sections, plywood sheets typically cost around $20 for a 4×8 sheet.

Using these methods can make the floor quieter, more stable, and help your flooring last longer.
