"Excellent, Sean did a fantastic job. We have not had any water come in since he repaired the crack and we have had a lot of rain . Sean and his father in-law "Poppy" were very personable and professional. We would highly recommend Sean and would not hesitate to use him again."

"Our foundation was seriously compromised due to water intrusion. Steve responded quickly and gave us an estimate at a great price. He was knowledgeable and informative. Dan and his team repaired our foundation, installed a drainage system and pump, as well as a vapor barrier. Our basement has been dry and free of mold since. The project was completed in a matter of days. I couldn’t believe how quickly they worked. I recommend the gurus to everyone who needs basement repairs. Thank you again!!!"

The crew also repaired our front steps and added bluestone details that gave the home a luxury appearance. Vinny and Nitin stayed involved during the entire project and made sure every concern was handled properly."

"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."

"They gave me a bid for some roof repairs. The technician was quick to respond and spent time going over everything with me. A very nice, professional guy. He contacted me back to set up a time and was prompt on arrival. His crew found a few additional things during the repair which they fixed without raising the cost of the original quote. They also had to call around several other companies to find the right color match for my replacement shingles. I would definitely use AB1 construction again. The prices are reasonable, he is professional, and pays attention to detail. All of these characteristics are often hard to find with a contractor these days. Awesome job and Iâ ll be calling him again, in the future, for other repairs and a full roof replacement when the time comes!"

"Sam and his team quickly identified my water issue, and fixed the problem within 2 days. Given the quality and speed of the work to repair a rather significant water issue, i contracted them for additional preventative maintenance on our 45 year old foundation, and 22 year old roof and gutters. Will most certainly engage them in the furture for any other related work."

"Sean (Shawn?) contacted me and was very helpful. I was seeking how to get in touch with Mid-Atlantic Wateproofing who did work for us last year, and needed to return to fix their sloppy work. Mid-Atlantic apparently has closed, at least temporarily, bur Sean worked hard at trying to find more information as to their status. Even though he had nothing financially to gain from me, I was very impressed that he willingly offered to help me in any way he could."

Foundation Repair FAQs, answered by experts

In most cases, yes, homeowners insurance will cover burst pipes, even if they run through your foundation. Not only that, but most home insurance companies will also cover any foundation repair you need done that resulted from the plumbing leak because your insurer will view the leak as an unforeseen and non-preventable issue.

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.

Yes, sustainable mixes and sealants minimize environmental impact.

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.
