"Lowcountry Foundation Repair came highly recommended by our contractor and they did not disappoint. The team was AMAZING! Super responsive, professional, very hard working and diligent. The team worked clean and did a gorgeous job on our crawlspace encapsulation. Alex and his team (Francis & Dedric) were THE BEST. We really had a great experience and are so grateful for their expert work. They're really an impressive team."

"On time. On budget. We had an interesting conversation over their contract but the owner worked with me to come to an equitable modification we could both live with. There was a part of the work bracing joist that was cut out for the toilet drainpipe that was not done correctly. Once I reported it, I was told I was correct and that they would have someone back to fix it correctly. All that happened as they said it would. No big job ever goes perfectly. These folks stood by their sales pitch and took care of everything very professionally"

"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

"Life Savers!! We live in an older house with a very small bathroom. We had a home inspection recently and were altered to some major subfloor, sill and joist damage. We knew it was in rough shape but the inspector used terms like “100% moisture and “previous repairs poorly completed”. I called a few other contractors and remodel companies that started to throw around some huge numbers and timelines to make the repairs. The consensus from them was the tub would have to be removed before they could do any subfloor repairs. In a house with one shower that wasn’t really an option for us. I saw the reviews for the Crawlspace Medic and decided to give them a call. It was the best decision I could have made. Sharon, Paul and Stanley were great; they made the process very easy and efficient from the initial phone call to the installation. Paul came out to do the initial visit (11/14) and assured me he had seen much worse and his company had developed methods to do all the necessary repairs from underneath the house leaving the current bathroom intact. The quote arrived the same day and was extremely reasonable. They got us on the schedule right away (11/20) and on the day of the repairs Nick and his crew arrived on time and were very professional. The job was scheduled for two days but they completed it in one and did a great job. We no longer have to worry about falling through the floor. They also provide a follow up inspection in 90 days and informed us of a couple other minor leaks that were noticed while completing the repairs. Crawlspace medic is a great company and I would 100% recommend them to anyone needing their services."

"I have a construction background but was unfamiliar with encapsulation as I just moved to Georgia. After extensive review of the encapsulation systems that were available in the area, and the price difference, I concluded the Crawl Space Doctor was a good fit. The main reason I chose the Crawl Space Doctor was because of their system. The other system was double the cost of the Crawl Space Doctor, so I carefully reviewed the difference and felt I would be getting equal benefits. I selected a 90 mil film for my project. Greg was very prompt and articulate in explaining his system and how his team would complete the work. Greg and his team did excellent work. They took out all of the debris under the house, informed me of a few problems they detected and repaired, then went to work putting the encapsulation system in place. They were very efficient. The crawlspace is doing exactly what I expected. The benefits of the Crawl Space Doctor's system are these: I am breathing better air quality. I am noticing a difference in the temperature of the house with reduced cooling costs, and expect the same on my heating costs. My insulation and floor joists are no longer moist and susceptible to mold. My heating and cooling ductwork will last longer with the humidity gone from the area. The dehumidifiers Greg put in do not run continuously, they will cycle off once the humidity desired point is reached. My hardwood flooring will not buckle in the future due to excessive humidity. My vents are now permanently sealed so rodents can't come into the house in the winter. I have peace of mind knowing my home is more protected with an encapsulation. It is a no brainer product in that it is a good investment all around. I would highly recommend Greg and his team at the Crawl Space Doctor. He has been doing encapsulations for years and is an expert in the field. His team does the work, but he personally oversees the project. You are in good hands with Greg McBride of the Crawl Space Doctor!! You will not regret spending less for top quality!"

"Powells concrete came out and removed our old driveway and put in a new one and poured a pad in the back for a large shed. Mr. Powells guys came out and did a phenomenal job. It was done quickly and efficiently! I couldn’t have asked for a better crew. I will definitely be using them for all my future concrete, and I highly recommend these guys at Powells concrete!!"

Foundation Repair FAQs, answered by experts

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.
