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.

We are very satisfied with our decision to have Tarheel basement systems encapsulate our crawl space. From the sales rep(Daniel Pike) to the installation by Robert Hacker,Austin Moody and Kenny we received in our opinion very professional services. The 3 gentlemen that performed the installation kept us informed and communicated exactly what they were doing from the time they were in route to the time they finished each day. They were very efficient, productive and the quality of their work was excellent! They were polite and respectful! I doubt that there is another company out there that can match the excellence of Tarheel basement systems!

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.

I went with Tarheel Basement Systems to have my crawlspace encapsulated. I liked the Sean Madden gave but I have to admit the follow up was spotty. I was given dates work would be done but I had to call to find out exact times. I expected a little more communication but, in the end, Tarheel showed up when they said they would, and they did the work they promised. Macai and Fred did a great job encapsulating the crawlspace. I'm pretty picky and I went down and inspected things myself. There is no way I could have done a good a job as they did. The work these guys do is grueling in unsavory conditions. I had a small issue with the crawlspace door and dehumidifier pump, but both were fixed in short order. In the end I'm happy with how things turned out and I would recommend Tarheel to anyone looking to get their crawlspace encapsulated.

After an annual maintenance service of our crawl space encapsulation and at the suggestion of Grant we decided to move forward with a plan to stabilize an area of our foundation that was weakened for some time. Tyree and Christian came out two days later to install beams and jacks to secure that part of the foundation. Tyree explained everything that was going to happen, what it would do to stabilize the foundation, and how long it would take. Everything went very smoothly and I went into the crawlspace to inspect the work and learn how the system would add support to the foundation. Tyree explained in terms I could understand. Both men were professional and finished in the time they laid out. This is my second experience with Tar Heel and both went well.

I had an excellent experience with Tarheel Basement Systems. They installed three permanent jacks to provide supplemental support, and the entire project was handled with care, professionalism, and clear communication. Nick Perfetti, the foreman, was outstanding from the very beginning. He took the time to thoroughly explain the scope of the project, what to expect during installation, and answered all of my questions before work began. After the job was completed, he walked me through the finished work in detail, ensuring everything was done correctly and that I was fully comfortable with the results. His knowledge and attention to detail truly stood out. Jordan Bumpers, the co-foreman, played a key role in keeping the project running smoothly. He was professional, organized, and clearly experienced, making sure the installation was done properly and efficiently. His leadership on-site was evident and contributed greatly to the quality of the work. Hunter Okonsky did an excellent job with the installation of the support system. He worked diligently, paid close attention to detail, and took pride in doing the job right. His professionalism and strong work ethic were very apparent throughout the process. Overall, the entire team was professional, respectful of my home, and committed to quality workmanship. I am very pleased with the results and would highly recommend Tarheel Basement Systems to anyone needing foundation or structural support work.

Tae. S, Edwin. C, and James. T handled my encapsulation, dehumidifier install, and sump pump install and they did an excellent job everything looks clean and well done these men definitely take pride in their work. Tarheel was willing to work with me in order to make things a little more affordable, with me doing some of the work up to the date of my install since I like to DIY to save money. and I’m very happy with the finished result. They are a little bit on the pricier side but with the quality of work and the quality of material they use I think its more then reasonable. There are multiple instances I’ve heard of other contractors / companies that would “provide” a similar service but would do it with cheap material and also do the bare minimum if even that in order to just take your money. You can’t go wrong with Tarheel. Cant recommend them enough. Almost forgot it was also a pleasure to work with Jason, when he came to give me the estimate. He also was the one to make suggestions on things I could do myself in order for me to try and keep the price a little lower and was very helpful throughout the entire process as I had a lot of questions for him.

On our one year follow-up inspection, items were identified and promptly corrected. Our front porch had settled about a 1/2 inch since it was raised. Jess W and Zach B came out and FULLY explained everything they were going to do. They went about their job immediately and completed it in short order, with NO shortcuts. They explained to me why it had settled in a year's time and what it would take to fix it. They quoted me the price and it was extremely reasonable compared to me having to acquire the materials and tools to do it. It LOOKS GREAT! We could not be more pleased. Thanks so much Jess and Zach!

I was extremely satisfied with the professionalism and hard work that Adam Canter (lead), Tim Witherspoon and Ryan Oldman displayed. They worked well together to complete the job on time and above expectations. I was impressed with the systems but even more impressed with the way it was installed, the efforts to control the dust and the cleanup that occurred throughout the job. I would suggest you ask for this crew by name. I had the work quoted by others but there was no warranty included. I think the extra money spent was well worth the quality, warranty and included follow-up inspections. The lifting peer systems installed closed the cracks in the brick veneer on the length of 3 sides of the house as planned. I observed the installation of the wall braces and could see the immediate reduction in bowing of wall. Very happy with results.

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.
