Crawl Space Repair

You may hardly, if ever, go into this area of your home, so it’s probably “out of sight and out of mind.” But it actually should be top of mind if you are concerned with the wellbeing of your loved ones.

Schedule Free Inspection


If you notice any of the following signs and symptoms around your home, you’ve got a crawl space problem on your hands. 

  • Musty odors and poor indoor air quality 
  • Feeling of dampness in the living area 
  • Buckled hardwood floors and sagging floors 
  • Mold growth 
  • Allergic reactions and worsened asthma symptoms 
  • Wood rot 
  • Increased energy usage and bills 
  • Pest infestations 

What’s under your house? The ground is, of course, but there could be something else beneath your living space.

You may hardly, if ever, go into this area of your home, so it’s probably “out of sight and out of mind.” But it actually should be top of mind if you are concerned with the wellbeing of your loved ones. A crawl space moisture or water problem can cause health, safety, and comfort issues in your home, such as mold, rotted floor joists, or a pest infestation.

There could be a host of reasons why your home is experiencing crawl space problems, but what it really comes down to is the construction of your house. Building practice traditionally has called for crawl spaces to be equipped with open vents for air drying purposes. 

But it is coming to light that this is an outdated and harmful practice. Open vents invite outside air, water, pests, and rodents inside to cause a myriad of additional problems.  

More than half of the air you are breathing in your home comes from the crawl space. So, whatever is in your crawl space, such as high humidity and mold, is circulating in the air throughout the rest of the home. This is because of the stack effect.  

The stack effect refers to the pattern of airflow in your house from bottom to top. Air pressure also comes into play with air movement. Air flows from areas of high pressure to areas of low pressure. When there is a greater difference between indoor and outdoor temperatures, the more significant this airflow becomes.

Even though you can’t see airflow, it might help to see this in action to get a better idea of how the stack effect works. No, Florida does not have a cold climate and it is not in the northern part of the country, but the Cold Climate Housing Research Center has a great YouTube video, “Your Nothern Home: Stack Effect,” that illustrates the stack effect. 

Here are other ways a vented crawl space and the stack effect impact your home: 

  • Water Intrusion — Any kind of water in the crawl space is bad news. Leaking and standing water is attractive to insects and rodents seeking shelter and a food source. As long as these pests have this kind of access, they will make your home their own and turn it into their breeding ground.

    When water comes into contact with anything in your crawl space – soft fiberglass insulation, wooden or metal supports, and even the dirt floor – it‘s going to eventually cause damage and failure of these items. It’s also one of the essential ingredients for mold growth.
  • High Humidity — Coupled with water, high humidity creates a recipe for disaster. By now, you’re well aware of Florida’s seemingly eternal humid air. When that air is vented into your crawl space and it meets water and other materials, it only creates more problems. High humidity – any level above 50% – contributes to mold growth, unpleasant odors, failing support systems, and more.

    It’s common for crawl spaces to have high relative humidity and moisture, but it is in no way healthy for you or your home. These conditions promote mold growth, especially on organic materials like wood and insulation. Moisture in the crawl space also can enter other areas of the home through wall, ceiling and floor cracks, and contribute to mold growth there. (Source: EPA)
  • Structural Issues and Sagging Floors — When warm and humid air is vented into the crawl space, your structural supports can take a hit. This can cause wood to rot and metal to rust and corrode. The results you could be experiencing in your home include sagging, soft, buckling floors, as well as warped and uneven hardwood floors.
  • Energy Loss — You seek relief from oppressive outdoor heat and humidity by retreating to your cool, air-conditioned home. But if that nasty air you’re trying to escape actually is underneath and inside your home, you could be overtaxing your AC unit. The air conditioner is going to have to work harder and longer to reach the comfortable temperature you want. This leads to wasted energy and high utility bills. 

Even after learning more about your crawl space, you might still be wondering what all the fuss is about. “Ok, so I need to repair my crawl space. What’s in it for me?” you might be asking. The answer: a lot. There are so many ways you, your family, and your home can benefit from conquering your crawl space with needed repairs. Here are just some of the perks: 

  • Improved Health and Quality of Life — Mold loves nothing more than your damp, humid, and wet crawl space. These nasty conditions can lead to and worsen respiratory conditions. But once you have properly waterproofed, encapsulated, and dehumidified your crawl space, you’ll be able to breathe easier, literally. The air quality will be better throughout your entire home, and your loved ones may not get sick or suffer asthma or allergy symptoms as much. 
  • Protected Safety and Structural Integrity — Any wooden or metal supports can easily fail when exposed to constant, excessive moisture and humidity, which leads to their compromised structural integrity. This puts your safety in danger, as a thoroughly saturated support or floor joist could fail completely and collapse. But a sturdier support system in a clean and dry crawl space is able to better protect your home and your family.
  • More Functional Space — You might feel like you’re running out of places to store items like holiday decorations or mementos. But if you have a crawl space that has been waterproofed and encapsulated, you can use this as extra storage space without the worry of any damage or loss.
  • Better Energy Efficiency — You could be wasting energy and throwing money down the drain with high electric and cooling bills. But once you encapsulate and insulate your crawl space, you could reduce your energy costs by 20%.
  • Improved Real Estate Value — Whether you plan to live in your house for the foreseeable future or want to sell it soon, your home will be on the market at some point. Is it ready and has it retained its value? A lot can affect the value of a home and its resale value, but it can take a hit due to damage of any kind. For example, foundational problems can reduce your home’s resale value by 10-30%, and homebuyers could have problems getting a mortgage. When selling your home, you must fill out a residential disclosure form and note any known past or current issues including with mold, water intrusion, flooding, and wood-destroying organisms. Show homebuyers you care about your house by having any problems fixed ahead of time. 

Now that you’re armed with more crawl space information, do you feel motivated and ready to take back your home with needed repairs? 

Before you start devising a plan of attack, first consider who will be completing this work. You have a wealth of resources at your fingertips with the internet and hardware stores, and you’re probably thinking about how you could save money by just doing it yourself. 

But crawl space repair is quite a commitment. And, as handy as you may be, it is best that you leave the fine details of it to professionals. This type of repair is a big deal, and a lot can happen if you try to DIY your way through it. Oftentimes, these DIY repairs don’t stand up to code or the test of time, and you’d have to spend more time and money to bring in a contractor to fix them. Have them fixed the right way the first time with a trusted company. 

Undoubtedly, you’ve probably heard about others’ terrible experiences of dealing with contractor mistakes and those who fail to follow through with promises and projects. But don’t let these troublesome tales completely influence your decision. There are companies out there who care about their work and want to help you. 

The best thing you can do is arm yourself with research and knowledge. Do your homework and find out as much about a company as you can before deciding who to hire. It’s important for you to feel comfortable with who you bring into your home, and to have confidence in the company’s ability. Read reviews, ask for references, and check out third-party resources like the Better Business Bureau. Make sure you ask for contractor must-haves like licenses, insurance, certifications, warranties, and other pertinent documentation. 

As you prepare to have your crawl space repaired, you should get quotes from at least three different companies. During your research journey, we at Florida Foundation Authority would be honored to have the opportunity to assist you. Let us prove to you that we are different from other contractors

When you choose to work with us, you become part of our family. From the initial inspection through the completion of beneficial repair projects, we’ll be with you every step of the way. 

After you contact us, we’ll schedule an appointment for one of our certified field inspectors to visit your home for a free inspection and estimate. During this consultation, the inspector will complete a thorough assessment of your crawl space, including looking for any signs of water intrusion, and structural and other damage.  

As the inspector shares his findings with you, he also will discuss your goals with a repair project and your budget. Then, he will put together an estimate that includes a plan with customized solutions that will meet your specific repair needs. The inspector also will go over financing options and answer any questions you may have. Take your time to sit with and review this estimate, and don’t be afraid to reach back out to your inspector with any follow-up questions or concerns. 

When you are ready to proceed with the work and sign a contract with your inspector, we will schedule the job with one of our highly trained crews. The crew will treat your home as their own, with the utmost care and respect, as they install the best solutions to protect your home. And their work is not done until you are completely satisfied with the job. So, if something comes up or the work isn’t living up to expectations, don’t hesitate to speak up. Plus, we offer service and maintenance opportunities to make sure our work continues to hold up and that your home is being properly protected. 

Because we are committed to you and the safety of your family and home, we use only quality crawl space repair solutions. Manufactured right here in the United States, each product is carefully designed and tested by a team of structural and geotechnical engineers. They are designed to work together, as well as with our other waterproofing and foundation repair solutions to give your home the complete protection it deserves. All our systems also come with a written warranty, giving you peace of mind. 

Here are different ways we address crawl space issues and their repairs: 

  • Waterproofing — If you’ve got a wet and leaking crawl space, we’ll attack this water at its source. Instead of ending up on your crawl space floor, our CrawlDrain™ perimeter drainage system will intercept water from the crawl space walls and floor. This water is then directed to a sump pump system to be pumped out of the crawl space and away from the home. We have a variety of SafeDri™ sump pump systems to meet your needs, including the SafeDri™ Pro Crawl Space Sump Pump System that is specifically designed to be compatible with our other crawl space waterproofing and encapsulation solutions.
  • Encapsulation — To prevent any further problems from excessive moisture in an unsealed crawl space, we will encapsulate the area to completely isolate it from the earth. Our CrawlSeal™ is a thick and durable 20-mil vapor and moisture barrier. It is waterproof and has been treated to resist mold and mildew. Even before placing this liner on the walls and floor, we can lay thick drainage matting on the floor to add to the strength of CrawlSeal™, as well as help direct water to the perimeter CrawlDrain™ system.

    Another essential piece in sealing the crawl space is to close off any vents. We can place durable, airtight vent covers on the home’s exterior to prevent infiltration from outside air, water, and pests.
  • Insulation — Soft fiberglass insulation can easily droop and harbor mold, but our rigid ExTremeBloc™ insulation panels that are placed on the crawl space walls will better insulate the area. These panels are mold and moisture resistant, and an integrated termiticide is added to deter termites below grade. CrawlSeal™ also helps insulate the crawl space, and spray foam can be added to rim joists to seal gaps around the perimeter of your foundation. These insulation methods help prevent wood rot and enable termite treatments.
  • Dehumidification — When sealing off the crawl space, it is important to condition the air inside, so it does not get stagnant. Our powerful, yet energy-efficient dehumidifier is the way to go. This low-profile unit cleans and filters the air, controls moisture and humidity, and reduces odors and the potential for mold growth. This is a self-draining unit that can be directed to drain into the perimeter drainage system or sump pump, so there are no buckets or reservoirs that you have to worry about emptying. 
  • Structural Supports — Uneven, bouncy floors are not only nuisances, but they also are signs that something is wrong with your home’s support system. Our galvanized steel IntelliJacks™ are more reliable supports that can stabilize and lift floors and floor joists back to level. They are designed to help stop settling, but they can easily be adjusted if any settlement occurs.
  • Access Points — Typical crawl space doors and exterior access points are wooden or metal and they can easily rot and rust when exposed to outdoor elements. But our durable plastic crawl space doors and access wells are safe, sturdy, and airtight.

We’ve saved the best for last, so to speak. The cost of repair is by far the most common crawl space concern we hear from homeowners. And that’s natural. Money matters, and so does your house. You want to make sure you’re protecting your home with the best solutions that also are cost-effective. 

To give you a general idea, crawl space repairs can range from $5,000 on the low end to $15,000 or more. Be aware, these are rough estimates, and the cost greatly depends on a variety of factors. There’s a lot to consider with crawl space repair including square footage, materials that will need to be used, the extent of any damage, labor, etc. All of these vary from company to company, so be sure to have a thorough conversation with your contractor about pricing specifics and payment options. 

If you are concerned with repairs being covered by home insurance, check into that with your insurance provider as all policies are different. 

And no two crawl space problems are the same. There is no magical “one size fits all” crawl space fix. We use customized solutions because every home is different and requires its own unique set of repairs. That’s why it’s so important for an inspector to visit your home and actually see what is going on.  

All this being said, when you decide to fix your crawl space, you are making an investment in your home. Can you really put a price on the health and safety of your family? 

You don’t have to live with the stress of crawl space problems. Fix these issues the right way the first time around with your trusted team at Florida Foundation Authority! We look forward to working with you!
