"I signed up to have a modular log home built on an existing foundation. The builder had a number of specifications that needed to be met to get the foundation ready for the new house. I contacted 8 other companies, but no one could help me with my long list of tasks. When I finally got ahold of Highlander Waterproofing, I started by telling them I was a problem child. I listed all the work that needed to be done and Mike told me that nothing on my list sounded sounded scary. I got a couple of visits from Mario, the manager, and Mike, the senior engineer, and one of their senior job bosses. They were all knowledgeable, helpful, positive, and suggested that I use steel supports instead of concrete to save space. Work started in August when Dewey and JT started knocking off the top 2 courses of block. "The Gents" - Dewey (the job boss) Devon, Jimmy, Matt, and Dave - did wonderful work. Because of Murphy's Law, we had to knock some walls down and rebuild them because of bowing, and we ended up adding an internal French Drain. They set rebar, poured tons of concrete, dug footers, put up steel support beams, installed glass block windows, put down sill plates, and rebuilt the front where the garage doors will be. I cannot even begin to say how pleased I am with the work they did. And they were a lot of fun to boot! They let me video them daily, tease them mercilessly, and they had the good grace to laugh when my dog made off with their breakfast jerky. There is still some work to do when the house actually gets here in April - insulating the outside wall, backfilling, putting the sump pumps in, rebuilding the center wall, and digging footers for the porch. I have absolute confidence in Highlander Waterproofing and "The Gents." I would recommend them highly and with no reservations to anyone who needs foundation work. I will add to this post with the final pictures in April."

"Excellent job repairing a crack in our poured concrete basement wall. Had to dig down to the bottom of the foundation, seal the crack, and back fill the hole - clean up was so good you didn't know work was even done. Very satisfied with the initial estimator, the job foreman, and the crew. The price was competitive with other estimates we received. Would recommend this company."

"We had 2 foundation cracks running from corner of basement window to the floor. Their recommendation was not to just fill in the cracks, as others suggested, but to also reinforce the structural integrity of the foundation with a solid steel plate bolted over the repaired crack. That approach made much more sense to me than the other recommendations I'd received. I hired them and they were onsite within 2 days and completed all work in a single day. We've since had excessive rain and the repairs have held up and the basement is still dry."

Their work was top notch and my basement is now completely dry. I would recommend their services to anyone with basement or foundation issues."

Foundation Repair questions, answered by experts

Not all cracks in brick indicate foundation problems. For instance, small hairline cracks can occur as a new construction settles. However, larger cracks are often a sign of a more severe issue. Indicators of a potential foundation problem include long horizontal cracks, "stair-step" cracks, vertical cracks that appear indoors, or any crack that widens at the top. Other signs of structural damage to look for are uneven floors and doors or windows that stick. These issues could be caused by problems with the soil beneath the home or an overgrown tree.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

Yes, foundation problems can cause ceilings to collapse or even your whole house to crumble. Left unaddressed, natural sinking can build up and eventually harm your home’s supporting structure, such as walls, beams, and frames. Your basement ceiling may be the first place to look for signs of a ceiling collapse caused by foundation problems.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Yes, you can fix a block foundation. It’s important to address the issue immediately and have a foundation repair professional understand the severity of the issue and determine the best course of action. If the wall collapses before the foundation is repaired, then you’ll have to reassess your entire foundation.
