Brad K. could not imagine owning a home anywhere but Johns Island, SC. He owns his own company and works very hard but he also likes to enjoy his free time. Johns Island allows him to get outdoors on hikes and going to the beach. Between working and getting out in his free time, he is often not at home. While leaving one day, he tripped over the sidewalk leading up the front door. He had not noticed that the concrete was sinking. Knowing the risk of a tripping hazard, he wanted to find a solution. One of Brad's friends was System Design Specialist Kendall Moore who worked for Cantey Foundation Specialists. He called him to see if there was a solution to this problem. Kendall came out to his home and took a look at the concrete slabs and determined that Cantey's PolyLevel process would make a perfect solution. The PolyLevel process would begin with small holes being drilled through the concrete slab. Then the PolyLevel would be injected underneath the slab as a liquid to fill all the voids underneath. The PolyLevel would harden into a solid within 15 minutes creating lift and stabilization for the concrete slab. Brad trusted his friends' opinion and scheduled an installation date. Production Team Leader Jeremey Wilson and Production Team Member Nick Collins came out and effectively injected the PolyLevel solution. Brad is back to being worry free in the great outdoors thanks to a perfect solution from Cantey.

Experienced Foundation Repair Contractor Serving Johns Island & Nearby

Are you worried about the state of your home's foundation in Johns Island? Over time, changing soil conditions, rainfall, and other factors can impact the area around your home, resulting in a sinking, settling foundation. When that happens, your home will display a range of symptoms, such as bowing walls, sagging floors, sticking windows, and more. These common foundation problems not only make life at home uncomfortable but are potentially dangerous.

While foundation problems tend to develop slowly, you will find yourself investing in costly repairs down the line if you don't keep an eye on them and make improvements when necessary. Additionally, when it's time to sell your home, you'll either have to resolve all foundation problems or take a hit on your home's overall value.

The good news? Cantey Foundation Specialists offers a variety of affordable, proven solutions for all of your foundation repair needs. Our specialists can inspect your foundation, pinpointing all problem areas and coming up with the best plan of action.

Foundation Problems We Fix:

  • House settling and sinking

Crawl Space Encapsulation & Sump Pump Installation Contractor

Humid crawl spaces are breeding grounds for mold and rot, causing structural and air quality problems for the rest of your home. What's even worse is that traditional methods of keeping crawl spaces dry, such as venting, have been proven time and time again to create more problems than they solve.

Cantey Foundation Specialists offers complete crawl space repair and encapsulation services using the CleanSpace® system. By installing a crawl space vapor barrier and additional products like thermal insulation, dehumidifiers, drainage matting, and a crawl space sump pump, you can create a fully enclosed, arid crawl space that won't allow for any moisture to enter.

If your crawl space has rotted or has sagging support joists, we can also assist by installing our galvanized steel crawl space support jacks. Your crawl space bears the weight of the floors above, so having stable supports is crucial!

Crawl Space Problems We Fix:

  • Buckled or cold floors upstairs
  • Humidity & condensation
  • Mold or moisture damage
  • Musty odors
  • Pooling water
  • Wood rot around framing & floor registers
  • Insect & pest infestations
  • Soggy, hanging, or fallen insulation

Our Crawl Space Repair Products:

  • CleanSpace® Crawl Space Encapsulation System
  • Crawl Space Sump pump installation & repair
  • Energy-efficient dehumidifiers
  • Crawl space supports
  • Crawl space insulation
  • Drainage systems & access wells
  • Vents, doors & access wells
  • Crawl space structural repair

Professional Aluminum Gutter Installation in Johns Island

Your gutters are more important than you may think. Healthy gutters help maintain a healthy home, transporting water and debris from your roof and safely depositing it away from areas where it can cause damage. While you might think faulty or ineffective gutters limit damages to the roof, think again. Foundations can be at risk as well. Without properly-fitted, high-quality seamless gutters, you might find yourself with a wet basement, leaky roof, or other avoidable household issues. You need a gutter contractor you can trust to make sure the job gets done right.

Cantey Foundation Specialists installs durable seamless gutters constructed from single pieces of high-strength aluminum. With this construction technique, our aluminum gutters avoid the pitfalls of traditional seamed gutters, like debris clogs. Seamless gutters are just one component of our fully-customized gutter systems. We install innovative gutter guards as well, which permanently eliminate the need to clean your gutters. We can guarantee a clog-free seamless gutter experience with safe water evacuation for years to come!

We are the Johns Island area’s premier gutter contractor, specializing in aluminum gutter installation, gutter guards, downspout extensions, and more. Call us today for your no-cost, no-obligation gutter replacement estimate!

Job Stories From Johns Island, SC
SmartJacks Restore Childhood Home in Johns Island, SC

Jeremy M. has lived in his Johns Island, SC home for as long as he can remember. He inherited his childhood home from his parents and could not imagine living anywhere else. He loves living in the low country and having the ability to enjoy the beach. The only downside to the low country for him has always been the toll it takes on his home. He had noticed that his living room floor was beginning to slope and knew that soil had washed out underneath his home. He had previously had some wood replaced by Cantey Foundation Specialists so he gave them a call for a new solution. System Design Specialist Kendall Moore arrived and inspected the crawl space and found that Jeremy's home just needed some extra support. Kendall recommended Cantey's patented SmartJack system to Jeremy as a lasting solution. The installation would start by removing sections of soil where the tightly compacted crushed stone would fill to create a stable base for the footing to be placed on top. A steel beam that would be specifically cut to fit Richard's crawl space would then be placed on top of the footing and attached to the top of the crawl space. These steel beams or SmartJacks could then be adjusted to lift the kitchen floor to its proper position. Production Team Leader Juan Ramirez, Production Team Member Matthew Williams, and Production Team Member Robert Gardner came out and successfully installed the SmartJack system. Jeremy is thankful to Cantey for restoring his childhood home and recommends this company to anyone in need of foundation repair.

I am a realtor and am under contract with a buyer for this property. The inspection report just came back saying that there was substantial moisture in the crawl space and recommended a dehumidifier or to close it off etc. Would you be able to tell me what something like that would cost on a 1228 square foot home? This was one of the items on the report: Sub-floor is saturated around several of the supply boots. Especially around the boots that termite below cabinet bases. Cabinet base supply boots should be re-located or equipped with directional boots.There are elevated levels of moisture on the floor joist and subfloors under the home (20% or higher). These areas can lead to mold, wood rot, or pest infestation. There was no visible damage at this time however, moisture control is needed. Recommend treating mold growth once moisture is corrected.
