Are Bouncy Floors Dangerous: 7 Ways To Fix Them

You’ve likely dealt with this before – the sensation of walking on a floor that bounces like a trampoline can be unsettling. Are bouncy floors dangerous? This thought can indeed be unsettling, and you’re right to wonder about their safety.

Bouncy floors can be very dangerous. This usually happens when the floor joists, which are the sturdy beams supporting the floor, become damaged or rotten. Usually, the ends of the joists are weakened where they meet the wall, causing bounciness in the floor.

In many cases, this occurs when moisture from the outside enters the building and saturates the ends of the joists. Over time, this leads to rot, which causes the joist ends to weaken.

Initially, the joists may shrink due to the rot, causing them to move and bounce within their housing in the wall or hanger. As the rot progresses, the joist end will deteriorate, leaving the joist unsupported.

This problem is commonly seen in joists within external masonry walls, where water seeps via the masonry into the joists ends.

It can also happen with first-floor timber joists above damp crawl spaces, where water can rise from the ground and soak into the joists, often accompanied by water vapor and condensation.

No matter how it occurs, this issue needs attention. Rot tends to affect multiple joists, and if the dampness continues, it’s likely to spread. Essentially, these affected joists rely solely on the floorboards connecting them to the stronger neighboring joists for support.

As a DIY enthusiast, I’ve fixed many bouncy floor issues myself, and based on my experience, I’m here to share seven effective ways to fix bouncy floors.

So, stay connected to learn how to address this common problem and make your floors safe and stable again.

While a crawl space dehumidifier can further control moisture levels, reported by civil engineer Jarek Kurnitski, (2).

Indeed, these fixes can ensure safety and stability in your floors. But there’s more to it as I have also wrote a whole guide on fixing nail pops in hardwood floors, and in the following sections, I’ll dive into seven DIY methods to fix bouncy floors in detail.

So, continue reading to discover comprehensive solutions to make your floors safe and sturdy again. Your home’s comfort and safety depend on it.

1. Crawl Space Vapor Barrier

The soil near a building can contain moisture in liquid and vapor forms. Liquid water from surface runoff or the water table can enter through cracks and openings, seeping into the soil and porous building materials like concrete, stone, and wood, researched by John F. Straube, Ph.D. Associate Member ASHRAE (3).

It is clear from the above research that the reason for house shaking but no earthquake is the moisture in floors that weakens them and that makes you feel like earthquakes or vibrations and even sometimes furniture starts moving when you walk on spongy floors.

Installing a crawl space vapor barrier is an effective way to prevent moisture issues under hardwood floors, which can, in turn, help stabilize your floors and reduce their bounciness.

Crawl spaces are typically damp and hard to control. There’s not much separating your floor from the messy crawl space below. This is where our vapor barrier comes into play.

Our vapor barrier acts like a powerful shield against moisture. It keeps water away, whether it’s from the ground or humid air.

Groundworks uses a 20-mil vapor barrier made from a tough material called polyethylene, which also has antibacterial properties. It doesn’t only keep water out, but it also improves the look of the crawl space.

When you install this vapor barrier in your crawl space, it stops moisture from moving upwards, a process known as the Stack Effect.

This prevents warm, humid air from reaching your floors and the structures underneath them. The result is that your floors stay stable and don’t bounce.

Beyond its moisture-controlling prowess, a crawl space vapor barrier plays a pivotal role in enhancing indoor air quality.

By preventing moisture-related problems like mold and mildew under hardwood floors, it helps maintain a cleaner and healthier living environment for you and your family.

Furthermore, the stability it brings to your floors not only ensures a more solid footing but also contributes to the longevity of your home’s structural elements.

So, in addition to addressing immediate concerns, a crawl space vapor barrier is a smart investment in the long-term durability and overall well-being of your home.

How Do Crawl Space Vapor Barriers Work?

Crawl space vapor barriers are like strong shields made of thick plastic. They’re put on the ground to stop water vapor from getting into your crawl space, the area under your home.

These barriers work really well to keep ground moisture out, but they can’t stop other types of moisture, like water from heavy rain or leaky pipes.

To be super safe, it’s smart to use a vapor barrier along with a waterproofing system to keep your crawl space really dry.

You might think you don’t need a vapor barrier if you live in a dry place like Arizona, but even there, the ground can have more moisture than you’d expect.

A study in Flagstaff, Arizona, found that sealing crawl spaces saved a lot of energy because it kept moisture out and made it easier to control the temperature inside homes.

Why Thickness Matters for Vapor Barriers?

When selecting a crawl space vapor barrier, its thickness matters because it directly influences its effectiveness and longevity.

By doing so, it keeps ground moisture at bay, effectively combating one of the leading causes of floor instability.

What sets this plastic sheeting apart is its versatility and durability. It’s thick and sturdy, so it can withstand the rigors of being exposed in the crawl space without getting damaged easily.

This was significantly super amazing for me because my crawl space lacked the protection of a concrete floor.

2. French Drain In Crawl Space (Perimeter drain)

During the summer, the relative humidity in the crawl space tends to stay quite high, typically ranging from 85% to 95%. This means that for several weeks, the conditions have been just right for water to condense, as reported by Samuelsson in 1994 (4).

Installing a French drain in your crawl space can be highly effective to fix these moisture related problems in wooden structures causing floors to bounce.

This drain, usually installed around the perimeter of your crawl space, helps manage excess water and moisture.

When it rains heavily or there’s groundwater seepage, a French drain collects this water and directs it away from your foundation, preventing it from saturating the soil and damaging your floor’s supporting structure.

This drainage system is particularly useful in areas prone to heavy rainfall or where the water table is high.

How Do French Drains In Crawl Space Work?

A French drain in your crawl space helps move standing water either directly to a sump pump or channel it outside via the main foundation wall.

After heavy rains, when your crawl space has water intrusion, a waterproof drainage system is also needed.

French drains work best when used alongside other drainage methods to fix water flow issues with sloping floors in a 100 year old house.

As an example, if your house is on a slope and water is flowing toward it, an exterior French drain uphill from your house can redirect the water away, keeping your basement or crawl space dry.

On a low-lying property, you’ll likely need a drainage system that encircles your house completely. Installing an exterior system during construction is easy and cost-effective.

But for existing homes, it’s tough and costly. You have to dig down to your crawl space or basement level, even if there are driveways, walkways, or plants in the way. Plus, fixing it if it gets clogged is tricky.

For fixing a wet crawl space or wet basement in an existing home, an interior French drain is more popular.

You’ll have to cut into the concrete or dig inside the foundation wall to create a trench. In this trench, you’ll need to place a gravel and perforated pipe that directs any water seepage to a sump pump pit.

Depending on your house’s layout, you might slope parts of the trench towards multiple sump pumps.

Why Durability Matters For French Drain?

Durability is an important factor to consider when installing a French drain in your crawl space or basement.

This is because the drain system is responsible for managing excess water and moisture, which can be highly damaging to the structural integrity of your home over time.

3. Sump Pump Drainage System

As per the report conducted by Thomas Scherer, Extension Agricultural Engineer, in the case of water seepage, the initial step is diverting it towards a floor drain. However, if the floor drain experiences obstruction or exhibits slow drainage, the recommended course of action is the installation of a pump (5).

When you install a sump pump in crawl space, it plays an important role in maintaining the integrity of your floor’s foundation by moving the water out from beneath your house.

It proactively removes water before it could cause damage to your crawl space. Without a sump pump, you’d either have to endure the drawbacks of a damp crawl space or manual water removal, often with uncertain results.

Mold growth in crawl spaces can pose health risks and threaten a home’s structural integrity.

Mold spores, carried by the stack effect, can lead to health problems, especially for those with allergies or weakened immune systems.

Additionally, mold can cause wood rot in crawl space components, resulting in uneven floors and weakened support.

Wet crawl spaces in North Carolina can experience freeze-thaw cycles and frost heave, which damage concrete surfaces and pillars.

This cumulative damage can lead to serious structural issues over time, including warped window frames, uneven floors, and wall cracks.

Maintaining a dry crawl space is crucial for a healthy home environment and a strong foundation.

How Do Sump Pumps Work?

A sump pump works by safeguarding the lowest section of your basement. In this area, a hole measuring about 2 feet in depth and 18 inches in width is excavated into your concrete floor, creating what is called a sump pit or sump basin.

When water gets into the basement, it flows into this pit. Imagine a float, like the one in your toilet tank, inside the pit. When the water level rises enough, it makes this float rise, and that’s the signal for the sump pump to start working.

The sump pump’s job is to take all that extra water and pump it out of the basement through pipes.

It sends the water far away from your house so it can’t cause any damage, resolving the issue of house shaking when walking.

Sump pumps are especially helpful when there’s heavy rain, big storms, or melting snow. Instead of your basement getting flooded, the sump pump keeps it dry by moving the water away.
