"Took waaaay to long. 6 months, albeit, we started in late November but it was the nicest winter in history. Promise was late February for completion. I finally conceded in June that they had finally met all contractual obligations. There were several reasons it took so long from my point of view: not showing up when they say they are, poor workmanship requiring lots of rework (all caught by me, not the so called Project Manager), no dedicated project manager, unclear instructions/requirements flowed down to the contractors sent to do the work, company too focused on the next jobs instead of completing this one, etc..I could go on and on...Damaged my driveway and blamed the driveway even though I asked upfront if there would be any harm to it. "No we do this all the time" was the response. Damaged my neighbors lawn and I'm still fixing that. Overall, a bad experience. I'd rate them a "D" but they did eventually fix most of the quality problems. The rest I have, or will take care of. Cutting the ties with this contractor. Would not recommend."

PowerBrace wall supports are installed, and the new steel reinforced concrete wall is formed around them to fully stabilize the bowing foundation wall.

"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. <br />"

"I contacted Jackson and Company to obtain <br /> a quote; Mr. Jackson contacted me within a few hours! Rick was polite and very <br /> professional during our conversations. He came out to see the cracks to ensure <br /> that my quote was accurate, especially since I had explained that someone had <br /> attempted to "repair" the cracks previously. Rick arrived promptly at <br /> my home and reviewed my situation. He answered all of my questions and <br /> addressed all of my concerns. He also explained that his work would be covered <br /> under a transferrable warrantee! I had several other quotes however no other company <br /> offered any type of warrantee. <br /> Rob arrived on time to do the job. Rob <br /> was so nice and professional; I was greeted with a smile and a handshake. I <br /> really wanted to see the process and he took the time to explain each step to <br /> me. He worked tirelessly to clean up the mess of the failed ?repair? I could <br /> not believe how much better it looked! He then proceeded to perform the repair allowing <br /> me to watch and take pictures, it?s quite the process. He left both areas that he <br /> worked on immaculate! <br /> I have such peace of mind now knowing <br /> that I will no longer have to worry about there being a huge puddle in my <br /> garage or basement or water spouting out of the cracks! I am so glad that I <br /> chose Jackson and Company to perform this work for me and I would recommend them <br /> to anyone! <br /> <br /> <br />"

"Wet Basement Solutions sealed the walls of our basement and installed a sump pump about three years ago. As of today, 5/2/23, our area has experienced a great deal of rain, which would have caused our basement to flood in previous years. Since WBS did their work for us, our basement has remained perfectly dry. My husband and I have been singing their praises for the last few days!"

"The project went very well. I was especially pleased with Paul's attention to detail -- after each day he'd turn off the lights, close the doors, put away tools, and put things back like he found them. It was hard to recognize that any work was even going on."

"The workman was very prompted and was here about 3 hours.  We had a spot in the foundation wall that would leak once in awhile with very heavy rain or a build up of snow and then a quick thaw.  He did a great job and everything around the area was cleaned up when he was finished. <br />"

FAQs for concrete foundation repair projects in Alton Bay, 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.
