"Our house was built in the 1890's. The foundation is stone with multiple generations of mortar in various states of disrepair. Our original plan of interior foam insulation was disrupted by some dramatic seepage on the north side of the foundation. Northern Basements came to provide us with a few options for repair. The diagnostic visit was very informative and the estimates reasonable. We chose the exterior drain option and sent in our deposit. The team that completed the work was amazing in what they accomplished and their very professional demeanor. We also purchased a dehumidifier system from Northern Basements. One year later all systems have worked very well. The basement is dry and we have had no other issues.

"After a poor driveway asphalt job at my mother in law's home was left incomplete by a scammer, I reached out on Angi's list for a reputable contractor. My mother in law, my wife and I were very impressed with Joey from Broman Contracting. He explained what was needed for the driveway in great detail, he was upfront about what he could do, and he answered all of our questions. Broman charged -for two driveways, half of what the scammer charged my mother in law for a partial and frankly crappy seal. We highly recommend Broman Contracting for whatever they say they will get done, because they do."

"Very responsive, highly professional, quality products and workmanship. Provided clear, comprehensive explanation of problem situation and solution options. Did not oversell; in fact, was very clear to point out what was not a significant issue needing a fix when the situation called for it. Highly recommended."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Great! Richard had a cancellation and asked if he could come in that time slot. We were delighted. He was prompt. Richard is knowledgeable, explained everything he was going to do, was very professional and friendly. He worked both inside and outside. The job looks very solid. Our realtor came over a few days later ( we are selling our house in the spring) and was very impressed with the workmanship. I would highly recommend Jackson Foundation Repair."

"We had a fairly new home that was 4 years old when we started to see cracks in the foundation. And whenever it rain heavy, water was seeping through the cracks on to the floor.  I called several people to come out and they gave me many different options as to how they would fix it. I was not happy with the advice until a contractor told me about Crack-X. It took several phone calls to finally get a call back. But I was given a quote over the phone and scheduled an appointment at the same time. The employee (Alex ) who showed up was terrific. He explained what he was going to do and proceeded to complete the job. It took several hours to finish the job. He mentioned that their work has a 10 year warranty. He also told me that I would never see water come from those cracks again. It has been almost 2 years since they completed the work, and I have to tell you that Alex was right. There has been not one drip of water that has come from those cracks and we have had many severe rainstorms over the last few years. I am totally satisfied with the results and would highly recommend Crack-X for peace of mind.

FAQs for concrete foundation repair projects in Bow, NH

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
