Do you see Cracks in your foundation walls?

If you are a homeowner, property manager, structural engineer, home inspector, or builder, you have probably experienced the problems caused by leaky basement and foundation walls. 

Leaking walls in your home or business, if left untreated, can lead to more serious and costly damage down the road. 

Water in the home can lead to mold, mildew, poor air quality, and further health issues. Structural damage may occur. And, even if water is not an issue, cracks can invite insects in to a home.

Services include:

We proudly serve our clients in: New Hampshire (NH), Massachusetts (MA), and Maine (ME).

My first experience with having foundation cracks repaired. This company couldn’t have made it any easier or more pleasant! Very efficient and knowledgeable! They fixed the cracks in a few hours! The staff were super nice, Chad,Lauren,Tom and Jacob. Thanks again! I would highly recommend!

Called and was referred to the owner directly. Was in the middle of finishing a basement and during our framing stages we quickly realized that we had a small leak through the foundation during a rainstorm. They came out immediately and rectified the situation for us allowing us to continue framing our basement. Thank you again for your kind, fast, clean, professional manner of handling your business. From one business owner to another thank you very much. Best – Pete

I had requested someone to call to discuss a leaking below-grade sump pump discharge. I received a call within 1 hour and an appointment setup for the following week. The repairman was courteous and worked quickly. The repair was successful and have had no leaks since. Great work done fast.

I had crack x come out last weekend for non-stop water coming into my basement. I called them during the night and my called was returned next morning by Doug - needless to say he was great! It was a Friday and I knew my chances of having them come out were slim with all the flooding. Needless to say they made it that night. Mica was the technician and he was amazing. As a member of the condo assocation board and I were watching him we both said it looks like he's performing surgery. He stopped the leak until they could get back on Monday morning. Mica worked for more than 5 hours on Monday to repair the problem and I haven't had a drop since. I forgot to say that we had another company come out on that Friday but they couldn't stop the leak. It was worth waiting for Crack X. They know what they are doing and are concrete experts! Thank you Doug and Mica~

Wonderful service. I called and Doug scheduled me right away. The Tech, Rob, was professional, friendly, knowledgeable, and fully explained and showed me everything he needed to do to correct the leak. We highly recommend them!

We were less than thrilled find cracks in our foundation prior to a home renovation. The contractor recommended we call Crack X and boy are we glad we did. They came out, explained the repair process and assured us it would be fine. The following day they showed up (on time!) and fixed everything for us. Everyone we dealt with was professional and willing to take them time to educate us on what they were doing and next steps. Thank you Crack X!

These guys are great! My house is basically located on a spring and my basement flooded constantly for years due to multiple faulty sump pumps and a bad sump pit set up, I finally called CrackX MV and I haven't had a problem for over 6 years! The owner personally worked to find the solution...
