7 Ways to Stop Bouncy Floors

Picture this: You’re walking across your living room, coffee in hand, when you feel it—an unexpected bounce underfoot. No, your home hasn’t turned into a funhouse. You’re experiencing a common but often overlooked issue: bouncy floors. The good news? Bouncy floor repair is possible.

We’ve created this guide to help you understand why your floors feel unstable and how to restore them. Here are seven proven solutions on how to fix bouncy floors in your house.

Bouncy floors aren’t a problem; they’re a symptom most likely caused by excessive moisture beneath your home. Crawl space moisture is the leading cause of mold growth, wood rot, and pest infestations. As these problems persist, they deteriorate the floor joists supporting your home. This deterioration causes sagging bouncy floors. 

Every problem has a solution, and we’re here to help you stand on solid ground again.

When floor joists fail, crawl space support jacks provide a solid foundation by evenly distributing your home’s weight. Support jacks eliminate unwanted bounce by stabilizing damaged beams and floor joists with their adjustable feature. Groundworks installs the SettleStop IntelliJack™ system, providing reliable support with over 24,000 pounds per jack capacity.

Crawl space jacks are tested and certified to the highest industry standards, upholding your home’s weight with incredible strength.

Crawl spaces are uncontrolled and often damp environments, with nothing separating your indoor floors from the moisture below—that’s where our 20-mil polyethylene CrawlSeal™ vapor barrier comes in. The waterproof protective shield blocks groundwater and humidity, preventing moisture while improving the area’s aesthetics.

By preventing the upward movement of moisture (known as the stack effect), the vapor barrier prevents warm, humid air from reaching your indoor floors and supporting structures, ensuring they remain bounce-free.

Bouncy floors in your house often signal crawl space moisture, meaning high humidity beneath your home and floors. We install our AquaStop crawl space dehumidifier to handle this moisture.  

According to the US Environmental Protection Agency (EPA), maintaining a relative humidity level under 60 percent is ideal. This lower moisture also helps prevent mold growth, pest infestations, and damaged floor joists.

The AquaStop Air System removes up to 100 pints of moisture daily, and its self-draining design means you never have to venture beneath your home to empty it. Moisture removal is often the most effective way to fix bouncy floors in house spaces.

Regulating airflow is vital for keeping your crawl space and floors dry and sturdy. It was once believed that crawl space vents promoted adequate airflow, creating a cool and controlled environment. However, the opposite proved true. These vents actually allowed humid air inside the crawl space, increasing moisture problems. 

Now, sealing crawl space vents is one of the best ways to reduce moisture, and our crawl space vent doors are designed for this purpose.

By limiting outdoor humidity, these doors prevent moisture buildup that can lead to bouncy floors in your house. When combined with other crawl space solutions, they help maintain a well-controlled environment beneath your home, making bouncy floor repair more effective.

Our crawl space insulation does double duty by keeping your floors firm and your feet warm. Unlike traditional fiberglass insulation, we use our patented ExtremeBloc™ insulation, which is better suited for crawl spaces.

Our insulation reflects heat from conduction, convection, and radiation thanks to its low thermal conductivity. In other words, it keeps heat where it belongs. With an impressive R-value of 11, it provides superior resistance to heat flow.

Beyond energy efficiency, ExtremeBloc™ also has built-in protection against termites and pests. By preventing energy loss and moisture intrusion it helps prevent bouncy floors in your house.

Our drainage systems and sump pumps protect your floors by preventing excess water damage. Groundworks installs crawl space drains with a specialized filtering exterior to keep out rocks, dirt, and debris, reducing the risk of clogs.

Meanwhile, a sump pump detects water in a designated sump pit and automatically pumps it away from your home. Optional backup batteries help by keeping them operational during power outages.

Together, these systems divert groundwater from the crawl space area, preventing moisture and making bouncy floor repair possible.

When in doubt, call Groundworks. Our crawl space professionals offer free inspections to diagnose the cause of your home’s bouncy floors and recommend the best solution.
