In our customers' own words:

CNT was the most professional company we have dealt with in years. They did what they said they would do in the timeframe they laid out. All of the worker's were very professional, polite , knowledgeable and friendly. The whole experience was a pleasure. Having been in business myself for 20+ years, I have to say CNT is a breath of fresh air to deal with. I wish more companies were this professional. From Sales thru all the work performed, everything went flawless and without any headaches for us. Once again, we are very pleased with CNT. Thank you to everybody who worked on our house.

Happy Customer

I have an issue with cracked concrete flooring on my side porch. Setting up an appointment for an estimate was very easy and the scheduler (Nicole) was pleasant, thorough, and professional. Todd was on time for the appointment, and texted me when he was on his way in advance. He looked under the house, and shared photos of what was going on down there. He advised that the foundation/support was solid underneath and therefore not an issue. He described options for solutions I could pursue, and recommended the least expensive / do it yourself one. Since I don't know anything about construction I'd asked a friend of mine who does to be here.

Another Happy Customer

We were extremely impressed with the service we received from CNT. Craig was diligent, knowledgeable, informative and friendly. He and Victor worked for hours to raise the side of our foundation that had sunk. They were successful! Craig explained every step of the procedure and advised us on how to repair the brick work once the raising and realignment was completed. We are new to South Carolina and are not familiar with “crawl space” foundations. Craig gave us some excellent advice on how to best maintain the crawl space in the home we just purchased.

FAQ

We’ve saved the most pressing concern for last, as it's one of the most frequently asked questions by homeowners. We understand the importance of getting clear answers and the frustration of not receiving them promptly.

On average, homeowners can expect to spend around $4,000 on crawl space waterproofing, with project costs typically ranging from $2,000 to $10,000. The return on investment for crawl space waterproofing is estimated to be about 30 percent.

The cost of wet crawl space repairs can vary significantly because each home has unique needs and repair requirements. What worked for your next-door neighbor’s home may not be the right solution for yours.

This is why it’s crucial to be present during an appointment with one of our certified inspectors. The inspector needs to assess the problems in your home firsthand to develop customized repair solutions tailored to your specific needs. They will consider factors such as your budget, repair goals, the severity of damage, square footage, and the amount of material required.

While the cost can vary greatly depending on the specific issues and needs of your basement, can you really put a price on your peace of mind and your family’s health? Think of crawl space waterproofing as an investment with invaluable benefits.

 

We are 100% committed to you and the health and safety of your family and home. That’s why we only install the best, proven, warrantied products that will effectively keep your crawl space dry. Our products are made right here in the United States and have been tested to withstand harsh leaking water conditions. This is our promise to you, your family, and your home.

Here are the solutions we use to fix your wet crawl space and how they work:

Drainage Systems – Interior drainage is the most effective way to tackle seeping water. First, we intercept the leaking water by excavating the perimeter of your crawl space floor and installing the BasementGutter™ interior drainage system in your sub-floor. This system captures seeping water from the walls and floor and directs it to a sump pump system. We also offer grated drainage pipe systems that can be placed in front of stairs and access points, which can be integrated into the rest of the perimeter drainage system.

Sump Pumps – After the leaking water is intercepted by interior drainage channels, it needs to be redirected away from your crawl space floor. Our systems discreetly collect and drain this water into a sump pump system, which then pumps the water out of the crawl space and away from your home. We offer several sump pump systems to meet your waterproofing needs.

Frozen Discharge Line Solutions – Water from the sump pump is pumped out through a discharge line, which can sometimes freeze or become blocked. Our FreezeGuard™ outlet can be attached to the exterior line just outside your foundation wall, preventing water from backing up and leaking into your crawl space.

Dehumidification – Keeping your crawl space and home safe and healthy also involves conditioning the air. Our powerful yet energy-efficient dehumidifiers clean and filter the air, control moisture and humidity, and reduce odors and the potential for mold growth. Unlike conventional dehumidifiers, our units are self-draining and can be directed to drain into sump pumps or perimeter drainage systems, so you don’t have to worry about emptying buckets or reservoirs.

As you explore potential waterproofing companies, we encourage you to strongly consider working with us. While you may think we're just like any other contractor, we assure you that we stand out with our world-class team and exceptional solutions.

First, we offer a free, no-obligation inspection and estimate. Once you contact us, our office team will schedule an inspection with one of our highly trained, certified inspectors. During this appointment, the inspector will conduct a thorough evaluation of your home's interior and exterior, identifying sources of water seepage. The inspector will discuss their findings with you and understand your goals for the repair project. As they prepare your repair estimate, they will tailor solutions to your specific needs, considering your budget and discussing payment and financing options.

Next is the work itself. When you decide to proceed with a repair project, our office will schedule the job with one of our experienced installation crews. The crew will treat your home with the utmost care and respect as they install tested and proven waterproofing solutions. If any issues arise during the process, don't worry. Your satisfaction is our top priority, and we will work diligently until you are completely satisfied with the job. We also offer service and maintenance opportunities to protect our work and your home.

After learning about the potential issues lurking beneath your home, you might be eager to visit your local home improvement store and gather supplies. While there are countless resources like video tutorials and blogs available, it's important to remember that wet basement repair is not a quick weekend project, even for the most capable DIY enthusiasts. Crawl space waterproofing is serious work best left to professional contractors.

DIY repairs like sealants or paints may offer temporary relief, but they won't address the underlying water and moisture problems. These solutions often fail, leading to peeling and flaking as water finds new ways to enter your basement.

Don’t waste time and money on quick fixes that won’t solve the problem. Trust a reputable company to fix the issues right the first time.

It's understandable to be cautious if you've heard horror stories about working with contractors. However, don't let a few bad experiences deter you from seeking professional help.

Before hiring a contractor, do your homework. Make sure you're comfortable with who you bring into your home. Request information about the company, including reviews, references, proof of insurance, licenses, certifications, a written contract, and examples of completed work.

And don't hesitate to reach out to us at CNT Foundation Services! We're here to help.

Now that you’re aware of common crawl space issues and their causes, don’t you feel motivated to tackle these problems and eliminate them for good? Why expose your loved ones to such conditions? Investing in reliable crawl space repair solutions offers countless benefits. Here are just a few:

Better Health and Quality of Life — Mold thrives in dark, damp areas like crawl spaces. Since more than half the air you breathe in your home comes from below-grade spaces, mold and dust mites in your crawl space can impact your respiratory health. Conditions such as asthma, allergies, and other respiratory issues can worsen or develop due to mold exposure. Keeping your crawl space dry can prevent these health problems. Additionally, running a dehumidifier will improve air quality and regulate moisture and humidity levels, contributing to a healthier home.

Protected Structural Integrity — Leaking water and failing walls often go hand-in-hand. Oversaturated soil next to your foundation walls can create hydrostatic pressure, leading to cracks, wall movement, and crawl space leaks. This is especially common in homes with block foundation walls, where water can seep through porous materials and accumulate inside the walls, compromising their stability. Proper crawl space waterproofing protects the foundation and the rest of your house.

Improved Energy Efficiency — Crawl spaces are naturally cooler because they are below ground. However, water leaks can cause even more significant temperature drops, making the floors above feel cooler and increasing the need for heating. High humidity levels also strain your air conditioner in warmer months, causing it to run constantly and driving up utility bills. Investing in reliable waterproofing solutions can improve your home’s energy efficiency and save money on heating and cooling costs.

Increased Real Estate Value — Your home’s resale value is influenced by various factors, including its condition. South Carolina homeowners are legally required to disclose any known past or current defects, such as crawl space leaks and pest infestations, when selling their homes. Addressing these issues beforehand shows potential buyers that you care about your home’s condition and value.

Don’t hesitate to invest in professional waterproofing solutions that ensure the safety, health, and value of your home.

Waterproofing your crawl space is crucial for protecting your entire home. While unfinished crawl spaces may seem to require less care or maintenance than rooms like your bedroom or living room, this is not the case.

Domino Effects

Water seeping into your crawl space can affect other areas of your home. The extra humidity from a leaking crawl space can spread throughout the house, even reaching the attic. This can make the air uncomfortably damp, warp wooden doorways and windowsills, fill your home with a musty odor, and promote the growth of mold and mildew. Keeping your crawl space dry prevents water damage from spreading throughout your home.

Crawl Space Waterproofing Is Easy

Waterproofing your crawl space is essential, and fortunately, it’s a straightforward process. Investing in waterproofing now is more cost-effective than paying for water-related damage repairs in the future.

Crawl space waterproofing, foundation drainage, and good yard drainage can also help prevent other foundation problems, such as soil washout. This reduces the risk of needing concrete slab repairs. Installing waterproofing systems like sump pumps and interior drains acts as built-in insurance for your home.
