Trevor,alec and noel were so polite and efficient. They did a fabulous job and fixed my foundation problem so quickly.I am very pleased with the work. I will certainly recommend you to my neighbors and family. Thank you for a job well done.
I had an inspection done in 2024, but was not ready to move forward with repair (my own anxieties) and there was no pressure from CNT staff. They encouraged me to take some time and follow up when I was ready. Fast forward to 2025, I decided to bite the bullet and get some home repairs knocked out including repairing the foundation (half side of the house had settled more than normal). Olivia quickly got me scheduled with Bill who re-inspected my home, confirmed with Kevin their findings and recommendations and got me scheduled for the project. Communication from the entire CNT team from start to finish was easy and seamless. Jeremy and his crew were also very communicative on their arrival, the process, and cleaning up. Aside from cost (quote still beat competitors), I'm happy with their work and feel a sense of relief from having the repairs done.
Wow amazing and professional services 💯
Dan Hinson came out to investigate the slab foundation issue. He was clear, and very insightful about what the issue was and what was likely the cause. This was a second estimate, and Dan was far and away more helpful in diagnosing the problem, In fact, he recommended taking about 6 months and see if the issue changed, as he thought it likely would not. Anyway, I was way impressed with his knowledge and competence and clarity of explanation. CNT Foundations is a winner because of people like Dan. Well done. Stephen Burnette, Aiken SC
Trevor did a great job leading his team of Noel & Rajim fixing my crawlspace and installing a dehumidifier and sump pump in 2 hoursPlus, they came early and really took care of business. Thanks guys!
CNT is awesome!! They went above and beyond for my family. They were efficient and so very kind to us. I would definitely recommend them to anyone!!
The entire process was seamless from start to finish. Trevor was very professional and communicated throughout the process. They arrived early and got to work immediately. Trevor, Alex, and Escamilla were top notch professionals, I highly recommend.
People were very professional from beginning to end. Very pleased with the outcome. Trevor, Sergio and Rejim did a great job on the install.
Dan Hinson was super helpful and honest!
Not just the best foundation company in the business, one of the best, most honest home repair companies I have worked with. I worked with Kevin. He was a pros pro. Honest, great communication and prompt service. Totally recommend them.

Problem signs to look out for when evaluating your home for foundation damage

If you’re searching for “foundation repair near me,” it’s likely because you’ve noticed some of the symptoms of foundation problems occurring inside and outside of your Charleston home, like foundation cracks or bowing walls. Your foundation provides support to your home’s floors, walls, and ceilings, so even small amounts of settlement can leave its mark on the rest of your home. Here are the top symptoms problems to look out for when evaluating your home for foundation damage:

EXTERIOR WARNING SIGNS

  • Sinking outdoor concrete
  • Collapsing retaining walls
  • Tilting & cracked chimney
  • Cracked bricks
  • Foundation cracks
  • Bowing walls
  • Sticking windows and doors
  • Settlement sinking
  • Foundation heave

INTERIOR WARNING SIGNS

  • Cracked sheetrock (wall crack)
  • Floor creaking
  • Sloped floors
  • Interior sticking windows & doors
  • Uneven floors
  • Floor and wall gaps
  • Separation in trim and molding
  • Spongy floors
  • Separations in cabinets

Foundation Repair Solutions

Because there is a number of unique causes of foundation failure, we offer a variety of foundation repair services and solutions:

found crawl space

Crawl Space Support Piers

Your foundation is probably built above a crawl space rather than above a basement. Therefore, your home may start to experience the ill effects of bouncy floors if the wooden crawl space beams start to decay or are overspanned.

While a crawl space is a cost-effective method to get your home off the ground, it can experience the ill effects of structural damage. Crawl space support piers will get your foundation back into good shape. CNT Foundations provides extraordinary foundation repair solutions to homes with crawl spaces. Call 843-577-7268 today for your free, no-commitment appraisal.

helical-piers

Helical Piers

Helical piers are used to stabilize foundations that have begun to settle because of insufficient help from the dirt beneath them. Foundation settlement can manifest in signs like:

  • Sticking doors and windows
  • Uneven floors
  • Tilting chimneys
  • Cracking walls
  • Floor and wall gaps

These issues can either be early indications of foundation failure or the underlying manifestations of structural damage. Helical piers are used to support your foundation in any areas where it may already be lacking support.

underpinning

Underpinning

If your home is experiencing foundation failure, foundation underpinning can increase your foundation depth and provide stability to a weak foundation. Underpinning works with your foundation to make it strong enough to support new or existing structures. CNT Foundations provides underpinning as a foundation repair solution you can trust. Call 843-577-7268 for your free, no-obligation estimate.

Foundation underpinning is the process of securing your home by reaching past the weakened soil your foundation is currently built on and installing helical piers. This method of foundation repair directly addresses problems caused by expansive soil or excessive moisture by transferring the weight of your foundation to soil that can support it. Underpinning methods like helical piers and slab piers transfer your home’s weight from surface soil to deeper, more stable soil.

slab-piers

Slab Piers

If you have a concrete foundation, slab piers can be utilized underneath your foundation to help balance out your home.

Foundation settlement is regularly caused by expansive soil, leaks under your foundation, or poor drainage around your foundation. These issues indicate one thing: soil that can’t hold up under the weight of your home. Gradually your foundation will begin to sink, and you’ll see the signs around your home like:

  • A cracked concrete slab
  • Cracked drywall
  • Gaps in your floors and walls
  • Stuck doors and windows around your home

These signs can end up seriously damaging your home and every one of them imply that your concrete slab foundation is sinking.

Channel Anchors

Wall Anchors

Have you seen bowing or suspicious cracking in your foundation walls? These signs could demonstrate severe foundation problems caused by hydrostatic pressure from the dirt around and under your foundation.

Wall anchors work best if you have a few feet around the sides of your home to provide room for installation. The wall anchors reach out from your foundation walls into the solid dirt beyond your home, supporting the foundation wall from the inside. Our wall anchors and foundation straightening services provide vital resistance against hydrostatic pressure and other outside forces with the goal that your foundation walls remain stable. After some time, these wall anchors can stop inward bowing and even enable your foundation to resume its original position.

Deep Soil Injection

Deep soil injection is a specialized concrete leveling technique used to address concrete surfaces that are compromised by unstable soil. This method involves injecting a stabilizing material, typically a polyurethane foam, deep into the soil. As the material expands and hardens, it binds with loose soil particles and fills the voids in the soil, increasing the soil’s load-bearing capacity. Some prominent advantages of deep soil injection are that it’s non-invasive, quick, and efficient. It doesn’t require a lot of time or space to work, and it comes at a fraction of the cost of replacing a concrete slab.

Crawl Space Wood Rot Repair/Replacement

A girder is a horizontal support structure that holds up the surrounding beams in a building. It can bear the load of the floor joists and distribute the weight evenly across the piers. Without a properly functioning girder, your home may develop issues such as sagging floors or wall cracks.

Over time, a girder can sustain damage and may need to be repaired or replaced to prevent foundation problems. Here are a few common issues that can affect your girder:

  • Wood Rot or Termite Damage: Many girders are made of wood. If your crawl space experiences termite infestations or high humidity with excessive moisture, the wood can deteriorate and need replacement. If wood rot occurs due to humidity, we recommend a moisture control solution to prevent recurring issues.
  • Sagging or Overspanned Beam: High humidity levels in your crawl space can cause the girder to sag. An overspanned beam can lead to uneven floors in your home. We will reinforce the girder with new support columns to prevent bending.
  • Sinking Columns: If your crawl space has a dirt floor, settlement may occur over time. Changes in moisture levels in the soil can either exert pressure on the piers or cause them to sink. In either case, the floor may start to sag, resulting in uneven floors in your home.
footing

Continuous Footing

A continuous footing spreads the weight of your home evenly across multiple points. If your crawl space has soil flooring, installing a continuous footing will help give additional support to the beams inside your crawl space. Typically, the balance is double the width of the foundation wall depending on how much the soil around your foundation can take. Soil can either expand or shrink depending on the moisture levels, which prompts settlement issues. Introducing a continuous footing to your structure will guarantee your home does not sink and cause foundation issues.

Our group at CNT Foundations will work with you to securely install a continuous footing to your crawl space. We have the experience and tools you expect that will help us keep your family safe during the construction process.

Garage Door Lintel Repair

A garage door lintel is a horizontal support beam above the garage door opening. Although very sturdy, factors like water damage, settling foundations, or poor construction methods can lead to cracks, sagging, or complete failure of the garage door lintel over time.
Repairing a garage door lintel is crucial for maintaining the structural integrity of your home. If your garage door lintel is damaged, you may experience difficulty opening or closing the garage door or notice a visible sag in the beam itself. These issues should be addressed promptly to prevent further deterioration and avoid potential safety hazards.
Garage door lintel repair methods can range from reinforcing the existing lintel to completely replacing it with a new, stronger beam. Our team will devise a personalized, suitable solution that restores your garage door lintel and safeguards the structural integrity of your property permanently.

Sagging or uneven floors can be caused by foundation settling, deteriorating floor joists, or insufficient support in crawl spaces. Common symptoms include noticeable dips, doors not closing properly, and gaps between baseboards and the floor.

If you hear popping, creaking, or shifting sounds, it could be due to foundation movement or settling. These noises often accompany other signs like cracking walls, sloping floors, or sticking doors.

Absolutely. Large tree roots can disturb soil and weaken foundation support, leading to cracks. Storms, such as hurricanes, can also impact foundation stability, particularly when heavy rain leads to soil erosion.
