Foundation Crack Repair

Our patented A-1 Method repairs foundation cracks caused by hydrostatic pressure, soil settlement, and temperature changes. Using non-invasive techniques, we inject specialized materials to seal leaks permanently, preventing water infiltration and structural damage. Ideal for poured concrete, block, and stone foundations, this solution avoids excavation, reducing mess and cost while ensuring long-term durability.

Basement Waterproofing

We specialize in basement waterproofing solutions that combat mold, radon, and humidity issues. Services include bulkhead waterproofing, sump pump installation, and seam repair. Our systems redirect groundwater away from foundations, using durable materials tested for New Englands freeze-thaw cycles. Commercial clients benefit from large-capacity dehumidifiers and elevator pit waterproofing tailored to property management needs.

Concrete Preservation

Our concrete preservation services address spalling, cracks, and deterioration in parking garages, loading docks, and commercial structures. Using epoxy injections and carbon-fiber reinforcement, we restore structural integrity without replacement. This extends the lifespan of concrete elements while maintaining compliance with safety standards for high-traffic areas like stairs and walkways.

Sump Pump Installation

We install high-capacity sump pumps to manage groundwater in basements and commercial properties. These systems automatically remove accumulated water, preventing flooding and mold growth. Paired with our waterproofing methods, sump pumps provide a comprehensive solution for properties in flood-prone or high-water-table areas across New England.

Commercial Waterproofing

Tailored for property managers, our commercial waterproofing services cover parking garages, elevator pits, and treatment tanks. We use industrial-grade sealants and membrane systems to protect against water damage, ensuring compliance with building codes. Our team addresses large-scale issues like damaged stairs and expansion joints, minimizing downtime for businesses.

Rich was incredibly knowledgeable. When I told him that an inspector had found a crack in my foundation, he just asked me what type of foundation it was. With nothing else but that, he described exactly what was going on, what the crack looked like, and how it would best be repaired. Ben came out and did the work quickly and cleanly. While he was there, he noticed something else that he wanted to ask Rich about.

Rich took the time and initiative to communicate with my inspector, and then called me to let me know what to look out for in the future. I hope I never have to call anyone about a foundation problem again. But if I do, I'll gladly call Rich and A-1.

Excellent work by A1. Very professional and helpful. Our foundation crack was kind of complicated because of where it was located, but A1 was totally willing to help us figure out what to do, and got the repair done pretty quickly. It's been two rainstorms so far and everything is looking great! Also--was blown away by the great price for the crack repair. We were SO worried that it was going to be a ton of money, and it turned out to be super reasonable.

I was referred to Rich by a colleague of mine and he was kind enough to take a look at my basement (not long after I called) and offer some crucial suggestions even before we touched on what A-1 could do to help with my cellar. He was very professional and called to follow up on next steps as I requested. Rich will be coming back after I finish running some tests. I would highly recommend them for their knowledge, professionalism and prompt call back which is rare these days!

Last year I had 3 Lally Columns added after I noticed one was failing. The service from A-1 Foundation was excellent and I had comfort in knowing that my house was supported properly. This May I noticed the remaining 3 showing signs of rust. So rather than put it off I booked for 3 more to be added. Ed just finished pouring the footings. He works clean and efficient. Once set I will have 3 more solid columns added. Honestly I never knew the importance of these metal poles in my basement. A-1 Foundation educated me on their purpose and last year showed me what to look for in my remaining columns. With their education, I decided to add the 3 this year. Since a rusting column will only get worse. I now share this with friends and family to check theirs and call A-1 if they have any concerns.

I called and spoke to Rich today regarding questions with potential repairs my block foundation may need. Rich spent a lot of time talking with me about what to do and how to do it myself if I wanted. It is a breath of fresh air to be able to work with honest hard working folks. Highly recommend them.
