In our customers' own words:

What a breath of fresh air! I had a great deal of concern regarding cracks around the concrete pillars of my home and the accumulation of water in my garage.

Dan was so very helpful. Though there was nothing I needed from CNT, he took the time to listen to my concerns, investigate, and provide me with potential solutions; he truly went above and beyond! Professional, courteous and HONEST…. I highly recommend CNT Foundations.

Susan Frickman

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.

C. Kathleen Donnelly

Another Happy Customer

I needed the lintel above my garage door shored up because of sagging which resulted in cracks appearing in the brick facia. I got CNT and another foundation company to give me an estimate. I went with CNT, even though they were the higher bid, because of their lifetime warranty.

I was not disappointed. Jeremy was a consummate professional. He patiently took the time to explain every step in the process and answered all my questions. His attention to detail was second to none. He went above and beyond in every aspect of the job and exceeded all my expectations. I recommend CNT because they hire people like Jeremy. I am certain I will use them again for any future projects.

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 are a number of unique causes of foundation failure, we offer a variety of foundation services to ensure your foundation and peace of mind are restored. Our residential Charleston foundation repair solutions include:

found-crawl-space

Crawl Space Support Piers

Your foundation in Charleston 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 in Charleston, 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 the areas around Charleston with 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.

wall-anchor

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.

cmu2

Concrete Masonry Units

When your foundation is sinking or settling, there are many different repair options available in Charleston. Concrete masonry units, or CMUs, are one great way to offer structural support that is both sturdy and cost-effective. These are extremely versatile and environmentally friendly, and can be used in a wide variety of applications. Because of their distinct advantages, CMUs are some of the best tools for addressing foundation settling in the Charleston area.

Here at CNT Foundations, we always use the most effective tools and techniques for the job, whether it’s to raise a home’s structure, level a pool deck, or repair a stairwell. CMUs, also known as architectural blocks, are cement blocks that come in many shapes and sizes, offering support underneath or around your property.

cmu

Remove/Replace Girder

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

Continuos 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.
