Our durable and waterproof 20-mil thick vapor barriers, combined with our state-of-the-art sump pump systems and superior dehumidifiers ensure your crawl space stays dry and clean for years to come. Additionally, our crawl space support posts ensure lasting structural stability.


CAUSES OF CRAWL SPACE DAMAGE

The biggest culprit of crawl space issues has to do with the way your home was constructed.

As warm air rises in a home, it leaks out of the upper levels. New air must enter your home to replace the air that has escaped. In fact, in a tight home, about half of the air escapes each hour out of the upper levels. This creates suction at the lower levels to draw in replacement air. In older homes, the air exchange rate can be as high as two exchanges per hour.

What this stack effect does is create airflow in your home from bottom to top. So air from the crawl space is drawn upwards into the first floor living area and then into the second floor. Of course, it dilutes with other air in your home, but building scientists say that up to 50% of the air you breathe on the first floor is air that came from your crawl space.

Therefore, whatever is in your nasty crawl space air (mold spores and humidity) is in the living area of your home and can negatively affect your family. If there is mold or mildew in the crawl space, mold spores are floating around upstairs that your family is breathing in.

So this idea that we put in crawl space vents and expect that air will flow in through vents on one side of the house and out through the vents on the other side, does not happen. What actually happens is air enters the vents in the front, enters the vents in the back, and enters the vents on the sides of the home and then it goes UP!

READ MORE ABOUT THE STACK EFFECT>

As cold air enters your crawl space, the stack effect carries that cold air throughout your home. What does this mean for your home?

The stack effect also allows dust mites, mold growth, and nasty odors to travel through your home into the air you and your family breathe. It also will create cold floors and a cold environment within your home, which causes you to use your home’s heating system more heavily, causing high utility costs. To keep your home warm, and the air you and your family breathe clean, it is important to keep your crawl space healthy and dry.

Many factors cause a damp and cold crawl space, like open vents, condensation, and water vapors. Rumors have it that insulation to your floors or roof of your home’s crawl space will help keep your home warm during the colder months, and is partially true; however, insulation ignores the real problem of moisture in your crawl space and will only be ruined by the moisture.

READ MORE ABOUT OPEN CRAWL SPACE VENTS>

Crawl space humidity has plagued homes in North Carolina since the first day they were built.

As the humidity levels rise in crawl spaces, moisture condenses on the surfaces, leading to serious problems in your home. These problems can lead to health issues and the need for expensive crawl space repair.

Most of the problems traditionally associated with damaged, rotting crawl spaces are due to basic flaws in the ways that crawl spaces were designed. When the frame of your home was first built, it was a large wooden box, with few, if any, holes in it.

Then came the other contractors. As plumbers, electricians, HVAC workers, and other professionals worked in your home, they began to cut channels in the walls and floors. Pipes, wires, cables, ducts, and other components were passed through, and your home’s construction was completed.

Then, over time, your home began to expand and contract. The once-tight seams began to warp slightly, and more crevices and openings appeared. There are a lot of openings that can develop between your first floor and your crawl space!

In your home, warm air rises, leaving through your attic and upper floors. As this happens, a vacuum is created on the lower floors. Air from the outside — and from your crawl space — is pulled upwards to fill the space.

If you have crawl space vents, they will also become part of the air movement in your home. As air is pulled out of the crawl space and up into the home, new air will be pulled in through these vents.

Here’s the key point: If the air outside is wet or humid, then your crawl space vents are bringing in moisture.

He is a very knowledgeable person and knows what he is doing. I enjoyed talking with him he is a very good people person. If I were to need any more service from this company I would definitely ask for Jr. He made sure that my doors would all latch due to jacking up the floors and made all the necessary adjustments to see that they did so. He did what it took to get the job done right. I wish he had it have been here the first time! Thank you John for a job well done! Ray Johnson

So beyond pleased with Tarheel Basement Systems! I'm a 2-year customer as of this week. A complete encapsulation, french drains, sump pump and dehumidifier. I receive an inspection each year around this time, my representative was John Snow, was amazing, so polite, punctual, kept me up to date on his arrival via text and phone, it was so pleasant seeing someone who "gets" customer service , and John does! He informed me my dehumidifier was not working, and would be replaced under warranty, and like clockwork as John said, he replaced it today! The easiest replacement ever, he arrived worked diligently, above and beyond! Again, beyond pleased!

I went into this basement project a little nervous, it seemed like a big commitment to put this amount of trust into Tar Heel Basement Systems. We had a long term problem with water ponding in the crawl space underneath our home anytime it rained. We had multiple people come out to try and diagnose the source of the leak, but none of them were 100% certain. Tar Heel Basement Systems blew me away immediately. The inspector, Dave Brereton, came out and within 15 minutes had identified the root cause as well as a plan to fix it. A few weeks later, the crew came out and completed the job in under two days. The difference is unbelievable. From Dave to the install crew, this company knows their stuff and conducts themselves professionally. A great experience, and I encourage anyone with similar problems to give them a chance. Thank you Dave and crew!

Tar Heel basement systems goes over and beyond their obligations to satisfy their customers even several years past. They came out and retaped some of the seams in the vapor barrier and cleaned the barrier where some water had pooled. I highly recommend them and their service technician (Jacob ) went over and beyond his duties to satisfy me as a customer. He readjusted my dehumidifier to the proper settings. Get them to help you! You won’t regret it! Superior service!

My Service Tech Matthew K did an awesome job identifying the problem (water seepage) and finding a way to address it without breaking the bank (a sump pump system). The foreman Grace H and her team were able to come out just a week or two after I scheduled the work, and they were fantastic to work with — on time, professional, friendly, and very patient even though I had a lot of questions. I would definitely recommend Tar Heel — I feel like this is one of the best investments I've made in my home.

Jeffrey Traub came out the day after I called the company. I had a large tree root that appeared to be going under my house and I was concerned it could cause cracks in my slab. He was on time and very thorough in examining my house. While he didn't find any problems he did spot a couple of issues for me to keep my eye on. He also explained I probably had lots of tree roots going under my house and that I just couldn't see them. My neighborhood had been built on land that was heavily wooded. He also explained HOW they fix a SLAB house that has foundation problems. I had envisioned all sorts of nightmare scenarios such as having to move all my belongings out and having my new floors ripped up. Luckily that is NOT how they repair it. Just knowing if that horrible day ever came where I would need their services, that it wouldn't be the nightmare I had thought, put my mind at ease. Jeffrey's explanation of the care they take to preserve my flooring while making repairs was very reassuring. The person who set up the appointment was also very thorough in asking questions to determine what the issue might be and which serviceman to send. Since I don't have a basement or crawl space I never thought I could have foundation problems. I was wrong but luckily I do not have any at this time and thanks to Jeffrey I am knowledgeable about what to look for in order to catch problems in their early stage when it is easiest and cheapest to fix. I would definitely recommend this company and suggest you ask for Jeffrey Traub to come to your house.

This review applies only to the person, Lisa, that helped complete our project. Our encapsulation project took over a year and a half to complete. It was a long process of phone calls not returned, emails not answered, and follow up not done. But, once Lisa became my contact, she made sure that everything was done when it was supposed to be done. That included multiple trips to fix problems found in inspections, multiple county inspections, and a refund for electrical work that I paid for twice. When Lisa said it would happen, it did. What a refreshing change from the previous 16 months. Great job, Lisa!

Best company ever. So conscientious. They understand your home is your biggest asset and any problems with it can induce great anxiety. Tyler was my technician at my annual inspection last week. He was on time (on the dot!) and very, very thorough. I appreciate this company that saw me through an extremely trying process in the best of times. At the time of the original basement restoration (2021), I was in the midst of terrible person trouble and they stuck with me until the end of the project. KUDOS to THBS and Tyler! Cannot recommend them enough and frequently do recommend them to anyone who needs this type of work.

If you need foundation work done, do yourself a favor and request Jay Yount at Tar Heel Basements. I had several companies come out, and Jay was the only one who approached my sagging floor issues with real expertise and a no-nonsense attitude. He spent hours carefully analyzing the problem and provided an honest, straightforward assessment with zero pressure. It's clear he takes pride in his work and values doing things the right way. More companies need people like Jay, and if his management is smart, they'll make sure he's moving up.

Why Crawl Space Repair and Encapsulation Are Important

The underside of your home may not seem important as it is a place that is rarely ever considered or visited, but this is not the case. Your crawl space is responsible for approximately 50% of the air that is in your home. This means that any mold or mildew, musty odors, or pest droppings in your crawl space are being circulated up through the air into the areas your family spends time together.

When it is exposed to the elements, your crawl space is susceptible to mold and mildew growth, excessive moisture from groundwater or floods, and unwanted pests. All these cause problems for your home’s structural integrity and indoor air quality. If visit your crawl space and notice pooling water or other damage, cleaning up any water is a good start, but encapsulating it is key. When you encapsulate your crawl space with a high-quality vapor barrier, you’re also improving your home’s energy efficiency and air quality.

Crawl Space Repair FAQs

The ideal humidity level for a crawl space is between 40 and 50%. Maintaining humidity within this range is crucial for preventing mold growth, wood rot, and poor air quality. To help achieve and maintain these optimal levels, we offer a range of solutions, including professional-grade dehumidifiers and comprehensive waterproofing systems. If you’re unsure about the humidity level in your crawl space or need help managing it, we encourage you to contact us for a free inspection.

We strongly discourage attempting to waterproof your crawl space without professional assistance. The complexity and potential hazards of the task require expert handling. Tar Heel Basement Systems offers specialized inspections and waterproofing solutions. Contact us for more information and to arrange a free inspection

Costs vary depending on the extent of damage, crawl space size, and required repairs. During your free inspection, a Tar Heel Basement Systems expert will recommend custom solutions and give a precise cost estimate without any obligation. We also take your budget into account and offer various financing options

Yes, in many cases, it’s possible to fix sagging floor crawl space with the right reinforcement, like our IntelliJack™ Crawl Space Jacks, without a complete floor overhaul. Our experts will provide a detailed evaluation during a free inspection and recommend the most effective sagging crawl space repair strategy. 

Addressing a crawl space foundation involves replacing the existing support piers or installing crawl space jacks to elevate the floor. Additional repair methods may also be recommended. Contact a local crawl space professional to ensure the repair is executed correctly from the onset.

Reasons For Crawl Space Repair and Encapsulation

If your home is old or newly built, it is important to make sure that there is some degree of waterproofing measures in place to protect it. Here are some of the most common reasons why waterproofing solutions and encapsulation is vital to the health of your home.

Water Damage

If you bought your home with waterproofing measures in place and still notice signs of damage throughout your home, it may be time for an inspection. As these solutions are not always a “catch-all” for problems, they are still prone to damage as time goes on. Clogged or broken sump pumps, open crawl space vents, plumbing leaks, and foundation damage can cause your dry and clean crawl space to become damp, humid, and unhealthy. If any of these are the case, you will need to address the underlying damage before repairing or installing additional waterproofing measures.

Exposure

In some older homes, open crawl space vents may still be in place. If this is the case and no other waterproofing measures have been installed, it’s important to encapsulate and waterproof your crawl space to prevent future water damage. It’s essential for an expert to inspect the underside of your home for any signs of damage that require crawl space repair or crawl space foundation repair before encapsulation. If solutions are placed over the damage, these problems could worsen over time and cause further destruction to your home and its structural integrity.

Deterioration

As with most home repair products, there is a time that they become less effective due to their relative installation date and any outside damage they are exposed to. The deterioration process is natural, but it comes with dangerous effects as it progresses. Therefore, it’s important to have your home regularly inspected with routine maintenance in place to ensure it stays in good condition.

If you’re researching the benefits of crawl space encapsulation or want to upgrade your current waterproofing systems, it’s important to repair any damage beforehand. At Tar Heel Basement Systems, our specialists are well-trained in inspecting crawl spaces and advising homeowners on the best steps to protect their home.

Crawl Space Repair and Encapsulation Tips for Your Home: The Good and The Bad

The Good

  • By encapsulating your crawl space, you’ll save money in the long run by improving energy efficiency. Your home’s heating and air conditioning systems can become overworked when dealing with an exposed crawl space. In the summertime when the weather is warm, your air conditioner will work harder to cool the air, and, in the winter, it’s the opposite. But when your crawl space isn’t encapsulated, these systems are constantly combatting the air temperature in your crawl space which, in turn, increases your energy bills.
  • When your crawl space is encapsulated with a vapor barrier, drainage matting, a sump pump system, and sealed crawl space vents, it’s able to reduce the amount of water vapor in the area. When you combine all these systems with a dehumidifier, you can be sure that your crawl space is fully protected from the effects of water vapor and the air quality in your home is clean and free of toxins and mold spores.
  • If you don’t have the time or money to encapsulate your crawl space but have open crawl space vents, it is imperative to seal them off to prevent more damage in the future. By sealing these vents, you ensure that any humid air in your crawl space doesn’t cause more mold and mildew issues. Sealed crawl space vents can also discourge unwanted pests from entering and making the underside of your home, theirs.

The Bad

  • If you have a sump pump in place but no backup installed, you may still run the risk of damage from a flood. If the power goes out or the lines clog, a battery-powered backup ensures that any leftover water gets efficiently pumped out and away from your home. You’ll have restored peace of mind whenever a storm comes your way.
  • Some homeowners believe that their crawl space only needs a few waterproofing measures in place to prevent damage. Unfortunately, this isn’t always the case. Although encapsulation and waterproofing go together, a drainage system or sump pump are just a few of the components needed to ensure a water-free crawl space. Without also installing a high-quality vapor barrier on the walls and floors, your home’s mold and mildew problems and wood rot are sure to continue.
  • Although you’re able to DIY many of your home’s repair projects, we recommend encapsulating your crawl space to not be one of them. As this is a complex process, missing any steps or failing to not address the root of the problem can cause even more damage in the future and more money for repairs. This also can lead to the current problems persisting and causing structural failure and the need for complete crawl space foundation repair.
