Say Goodbye to Sagging Floors: How to Fix Hardwood Floor Lifting in Simple Steps!

Hardwood floors are a beautiful and durable addition to any home, but they can sometimes be prone to lifting. This can be a frustrating problem, as it can make your floors look uneven and can even be a safety hazard. If you’re wondering how to fix hardwood floor lifting, you’ve come to the right place. This blog post will cover the causes, solutions, and tips for preventing this common flooring issue.

Understanding Hardwood Floor Lifting

Hardwood floor lifting occurs when the boards separate from the subfloor, creating gaps and unevenness. This can be caused by a variety of factors, including:

• Moisture: Moisture is a primary culprit. Water can seep into the subfloor from leaks, spills, or even high humidity. This moisture can cause the subfloor to expand, putting pressure on the hardwood floorboards and causing them to lift.
• Insufficient Subfloor Support: A weak or improperly installed subfloor can also contribute to lifting. If the subfloor is not strong enough to support the weight of the hardwood floor, it can sag, leading to gaps and unevenness.
• Improper Installation: If the hardwood floor was not installed correctly, it can lead to lifting. This could include using the wrong type of nails, failing to acclimate the wood to the humidity levels in your home, or not securing the boards properly.
• Expansion and Contraction: Wood naturally expands and contracts with changes in temperature and humidity. If the floorboards are not given enough space to move, they can buckle and lift.
• Shifting Foundation: In some cases, a shifting foundation can cause the subfloor to move, leading to hardwood floor lifting.

Diagnosing the Problem

Before you start fixing the issue, it’s important to understand why your hardwood floor is lifting. This will help you choose the right solution. Here are some steps to diagnose the problem:

• Inspect the Subfloor: Look for signs of moisture damage, such as warping, buckling, or soft spots.
• Check for Gaps: Examine the gaps between the floorboards and the subfloor. Are they consistent or are they concentrated in specific areas?
• Look for Signs of Unevenness: Is the lifting concentrated in one area or is it spread throughout the floor?
• Consider Environmental Factors: Have there been recent changes in humidity levels or temperature in your home?

How to Fix Hardwood Floor Lifting

Once you’ve diagnosed the problem, you can choose the best solution. Here are some common fixes for hardwood floor lifting:
1. Addressing Moisture Issues:

• Identify and Repair Leaks: If you suspect a leak is the culprit, find the source and repair it immediately.
• Reduce Humidity: Use a dehumidifier to lower the humidity levels in your home, especially during humid seasons.
• Improve Ventilation: Ensure proper ventilation in your home to allow for air circulation.

2. Strengthening the Subfloor:

• Add Additional Joists: If the subfloor is weak, you may need to add additional joists to provide more support.
• Replace Damaged Subfloor: If the subfloor is damaged beyond repair, it needs to be replaced.

3. Re-Securing the Floorboards:

• Use Floor Screws: You can use floor screws to re-secure loose floorboards. Make sure to use screws that are long enough to reach the subfloor.
• Use Wood Glue: Apply wood glue to the underside of the floorboard and re-secure it to the subfloor.

4. Addressing Expansion and Contraction:

• Leave Expansion Gaps: Ensure that there are expansion gaps around the perimeter of the floor and between the floorboards.
• Use a Moisture Barrier: Install a moisture barrier under the subfloor to prevent moisture from seeping up.

5. Foundation Issues:

• Consult a Professional: If you suspect foundation issues are causing the lifting, consult a structural engineer or contractor.

Preventing Hardwood Floor Lifting

Here are some tips to prevent hardwood floor lifting in the first place:

• Acclimate the Wood: Before installing hardwood floors, acclimate the wood to the humidity levels in your home for at least 72 hours.
• Proper Installation: Ensure that the hardwood floor is installed correctly by a qualified professional.
• Maintain Proper Humidity Levels: Keep the humidity levels in your home between 30% and 50% to prevent expansion and contraction of the wood.
• Regular Inspections: Regularly inspect your hardwood floors for signs of lifting or other damage.

When to Call a Professional

While some repairs can be done DIY, it’s important to know when to call a professional. If you’re dealing with:

• Extensive Lifting: If the lifting is widespread or severe, it’s best to call a professional.
• Moisture Damage: If you suspect moisture damage is the cause of the lifting, a professional can help identify the source and repair it.
• Foundation Issues: If you suspect foundation issues are causing the lifting, a professional can diagnose the problem and recommend the appropriate solution.
