If you’ve ever noticed gaps, lifting, or separating in your flooring, you’re not alone. At Flooring Services, we’ve seen this issue repeatedly, especially in rental properties or homes where the installation wasn’t handled properly. A recent online post sparked quite a debate about whether flooring separation is due to tenant misuse or poor installation. The reality? The answer usually lies in how the flooring was installed and maintained.
In this post, we’ll discuss the most common reasons flooring separates, the role of installation and maintenance, and how to prevent it from happening in your home.
1. Poor Installation Practices
One of the most common culprits of separating floors is improper installation. Even the best flooring products can fail if the installer cuts corners or skips critical steps. Some common mistakes we see include:
- Skipping a vapor barrier: A vapor barrier prevents moisture from seeping up through the subfloor and warping the planks. Without it, you risk swelling, buckling, and separation.
- No proper floor prep: Planks won’t lock tightly if the subfloor isn’t level or properly cleaned. Over time, they can shift and create gaps.
- Improper staggering: Manufacturers provide guidelines on how planks should be staggered. When installers ignore these rules, weak points develop in the floor, leading to separation.
- Not leaving expansion gaps: Flooring expands and contracts with temperature and humidity. The pressure can force boards to lift or pull apart without proper expansion gaps along the walls.
In the Reddit case, several commenters noted visible signs of poor installation—uneven surfaces, improper plank staggering, and missing barriers. These mistakes put tenants in a tough spot, but they’re unfortunately common in low-budget installs.
2. Subfloor Issues
The condition of your subfloor is just as important as the flooring itself. If your subfloor isn’t level or has leftover trowel marks from tile removal, the flooring on top won’t sit evenly. As weight shifts across the surface, boards can separate. This is why professional installers always inspect and prepare the subfloor before starting a project.
Another issue is moisture. Concrete subfloors in basements, for example, naturally release moisture. Without proper barriers, that moisture will wreak havoc on laminate or vinyl planks.
3. Furniture and Everyday Use
While installation is often to blame, everyday use can contribute to flooring damage too. Rolling desk chairs, for example, can cause wear and tear on floating floors like laminate or LVP (luxury vinyl plank). If chair mats aren’t used, the constant rolling pressure can stress the seams and eventually break them down. In the Reddit post, one commenter pointed out that while the separating planks were due to poor installation, the damage under the office chairs was more likely from misuse.
The lesson here? Use protection under heavy furniture or rolling chairs. Small preventative measures, like chair mats or rugs, can make a big difference in extending the life of your floors.
4. Temperature and Humidity Changes
Floors naturally expand and contract with changes in temperature and humidity. This is why installers leave expansion gaps around the perimeter of the room. Planks can shift and separate if those gaps are missing or if climate conditions fluctuate drastically.
Humidity is a year-round challenge in Charleston and the Lowcountry, where Flooring Services is based. Proper installation techniques and the right underlayment materials are critical to protect against these environmental changes.
5. Low-Quality Materials
Not all flooring is created equal. Cheaper materials are often less durable, more prone to swelling, and harder to lock in place. As one Reddit commenter noted, tenants usually pay the price when landlords cut costs with budget flooring and unlicensed installers.
That doesn’t mean you need the most expensive flooring on the market. But investing in quality materials, installed by licensed professionals, will save you headaches (and money) down the road.
6. Who’s Really Responsible?
One of the big debates in the Reddit thread was whether the tenants were responsible for the flooring damage. Here’s the truth: separating floors almost always points to an installation issue, not tenant misuse. Yes, office chair wheels without mats can cause localized damage, but widespread gaps and lifting are signs of poor workmanship.
If you’re in a rental situation and being held responsible for flooring separation, you may have grounds to dispute it. Take photos, document past repairs, and note any comments made by maintenance professionals about the flooring’s quality.
7. How to Prevent Flooring Separation in Your Home
If you’re installing new flooring or already dealing with separation, here are a few tips:
- Hire licensed professionals. A quality install is your first line of defense.
- Ask about vapor barriers and underlayment. Don’t let installers skip these steps.
- Check the subfloor. Make sure it’s clean, dry, and level before installation.
- Use mats under rolling furniture. Protect your investment from everyday stress.
- Control indoor climate. Use dehumidifiers or humidifiers as needed to keep your home balanced.
