Crawl Space Repairs in Alabama + Tennessee

The crawl space beneath your home plays a bigger role in your family’s comfort, health, and safety than most homeowners realize. The air in your crawl space circulates into your living areas, the structural timbers in your crawl space support your floors, and the moisture level in your crawl space determines whether mold, wood rot, and pest problems take hold. When something goes wrong in the crawl space, the effects are felt throughout the entire home.

When you need a team with the experience and skills to diagnose and repair crawl space problems correctly, homeowners throughout Alabama and Tennessee trust The Crack Guys. With over 20 years of combined experience, our highly-skilled technicians deliver lasting solutions that protect your home from the ground up.

Crawl Space Waterproofing

Water in the crawl space is one of the most damaging problems a homeowner can face. Whether it enters through plumbing leaks, groundwater seepage, or poor drainage, moisture in the crawl space raises humidity levels, promotes mold growth, accelerates wood rot, and attracts pests. The Crack Guys address crawl space water problems with a comprehensive range of waterproofing solutions. Our CrawlGuard™ interior drainage system channels water away from the foundation and directs it to a sump pump basin. We offer three reliable sump pump models to fit any home’s needs. To fight excessive moisture in your crawl space, we install heavy-duty encapsulation across the floor and walls of the crawl space to block moisture intrusion from the ground up. And our Liquidator 120C™ dehumidifier removes up to 120 pints of water per day to keep humidity consistently below the 50% threshold at which mold and wood rot thrive.

Crawl Space Mold Remediation

The dark, damp conditions of an unprotected crawl space make it a natural environment for mold growth. Because over 50% of the air in your living quarters originates from the crawl space below, mold beneath your home is never truly contained. It travels upward into the rooms your family occupies every day, affecting indoor air quality and posing real health risks. The Crack Guys use our proven MoldGuard™ System to eliminate existing mold through professional antimicrobial treatment. In cases of extensive mold growth, our highly-skilled technicians also perform soda blasting to remove mold colonies from all affected wood surfaces before applying the antimicrobial solution. Once remediation is complete, we recommend pairing it with crawl space waterproofing and humidity control to help prevent mold from returning.

Floor Joist, Subfloor, and Beam Repair

The floor joists, subfloor boards, and support beams in your crawl space are the structural foundation of every floor in your home. Moisture exposure, wood rot, termite damage, and age can all weaken these components over time, leading to bouncy, sagging, squeaking, or uneven floors. The Crack Guys address damaged floor joists by installing sister boards alongside compromised joists to restore strength and stability. For sagging or sinking floors, we install our custom-built Samson Floor Supports™, which rest on a concrete base with adjustable steel columns capable of supporting up to 80,000 pounds. Whether your floor system needs spot repairs or more extensive work, our highly-skilled technicians have the experience to restore it correctly.

How To Identify Crawl Space Damage

Because most homeowners rarely visit their crawl space, problems can develop undetected for months or years before becoming serious. Fortunately, crawl space damage often reveals itself through signs that are visible inside the home. Watch for any of the following:

• Musty or moldy odors inside the home
• Sagging, bouncy, squeaking, or uneven floors
• Gaps between the floor and baseboards
• Unexplained moisture or water on the crawl space floor
• Cracks in walls, ceilings, or floors
• Higher than normal energy bills
• Evidence of pest activity such as termites or rodents

If you notice any of these signs, do not wait. Crawl space problems worsen over time and become more costly the longer they go unaddressed.

How do I know if my crawl space has a problem?

Crawl space problems often reveal themselves through signs that are visible inside the home. Watch for musty or moldy odors, sagging or uneven floors, gaps between the floor and baseboards, unexplained moisture or water in the crawl space, cracks in walls or ceilings, higher than normal energy bills, and evidence of pest activity such as termites or rodents. If you notice any of these signs, contact The Crack Guys for a free inspection. Our experienced consultants serve homeowners throughout Alabama and Tennessee and will assess your crawl space at no cost or obligation.

Why is water in my crawl space such a serious problem?

Water in the crawl space raises humidity levels, promotes mold growth, accelerates wood rot in floor joists and support beams, and attracts pests like termites and rodents. Because the crawl space sits directly beneath your living areas, the damage it sustains affects the structural integrity of your floors and the quality of the air your family breathes. Left unaddressed, water intrusion in the crawl space leads to increasingly costly repairs over time. The Crack Guys recommend addressing crawl space moisture problems as soon as they are discovered.

What is crawl space encapsulation and do I need it?

This method of crawl space protection involves installing heavy-duty encapsulation across the floor and walls of the crawl space to create a sealed, controlled environment that blocks moisture intrusion from the ground up. It is one of the most effective long-term solutions for controlling crawl space humidity, preventing mold growth, and protecting the structural components of your home. The Crack Guys offer crawl space encapsulation options ranging from a 12 mil extra-tough woven polyethylene liner to a 250 mil radiant cord-reinforced liner depending on the needs of your home. Whether encapsulation is right for your crawl space depends on its current condition, and our experienced consultants can assess that for you at no charge.

How does crawl space mold affect the air inside my home?

Over 50% of the air circulating in your living quarters originates from the crawl space below. Because air naturally moves upward through a home, mold spores and contaminants present in the crawl space travel up through the floors and into the rooms your family occupies every day. Exposure to mold spores can cause nasal stuffiness, eye irritation, wheezing, and skin irritation, and those with respiratory conditions or compromised immune systems are especially vulnerable. The Crack Guys’ MoldGuard™ System eliminates existing mold and pairs with waterproofing and humidity control to help prevent it from returning.

What are the signs of damaged floor joists or support beams in my crawl space?

Common signs of damaged floor joists or support beams include bouncy, sagging, squeaking, or uneven floors, gaps between the floor and baseboards, and visible wood rot or rust on components in the crawl space. Moisture exposure, termite damage, and age are the most frequent causes of floor system deterioration. The Crack Guys repair damaged joists by installing sister boards alongside compromised ones and install our custom-built Samson Floor Supports™ to lift and stabilize sagging or sinking floors. If you notice any of these signs, contact The Crack Guys for a free inspection.
