"Had a Sump Pump and French Drain installed, Mold Removal and a major repair to a foundation wall. Absolute Waterproofing and Renovations were highly recommended to me by a gentleman that does business with them everyday. Lou and his guys came when he said they would, finished when they said they would. They protected my house from dust and dirt by covering everything with plastic. The price was the most reasonable in comparison. They were professional, clean and trustworthy. They actually found a gold wedding band that was missing for months and were honest enough to return it to us. I'm 100% satisfied with the the work that was done and highly recommend them!"

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"We contacted Tri Stone because parts of our home were showing signs of sinking and we were extremely worried that the foundation was the cause. They inspected everything, explained what needed to be strengthened and carried out the foundation repair work for us. This was the kind of job that can make any homeowner nervous, but they kept us informed throughout the process. We’re very thankful we got it taken care of."

"OUTSTANDING! This company is so honest and leads with great integrity that the inspector Tony identified the root cause of where our water was leaking into our basement and said we may not need to install French drains which would have cost us about $4,000. Our previous owner drilled holes into our sidewalk outside of fireplace that leads to our basement for termite treatment. The cement covering holes eroded and water was leaking into the basement. We covered the holes with cement 2 days ago and with this passing rain not one drop of water is in the basement. We've had three other basement waterproofing companies come to her house and no one noticed it except for blue umbrella waterproofing. The owner even took the time to call me to ask how the inspection went. This is the only company I would use in the future."

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

"Those of us in Jersey can attest that the rain has been super problematic this year. After ten years in my home, my basement was flooding consistently. I contacted Bob at Westher Tite as well as 2 or 3 other companies for emergency diagnosis and repair. Bob was the first to reply, very informative and had the issue fixed within the week! He and his crew were punctual and professional. Once the work was completed, my basement was spotless. No signs of moisture or dust anywhere! Bob was helpful in explaining everything. Pricing was fair not the most nor the least expensive estimate. The VALUE, however was spot on! The rainfall hasn’t let up a bit and not a drop of water in my basement."

"Pat thoroughly inspected the property inside and out and made holistic recommendations to solve the suspected water problems. He was very professional and took time to explain his recommendations and considerations. Unlike the other companies I met with, he also provided options depending upon my budget and desire to start small or big and was willing to recommend a contractor to take down and rebuild the finished part of my basement. Overall estimate was comparable to others, approximate cost was for full basement and several windows. I ended up choosing a different company but the choice was close. I'd recommend contacting Arid when considering basement waterproofing.

Foundation Repair FAQs, answered by experts

If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.
