"Mixed review I had spoken with other radon remediation companies and received quotes before meeting with Erickson Foundation Solutions. The salesman, Chris, seemed much more thorough in his approach and he gave a presentation explaining radon, its danger and the process to remove it. The quote was slightly higher than another quote, but I felt more confident. And with the added fan moisture guard, the system came with a 10-year warranty. So I agreed to the proposed plan and paid a deposit. Later I decided to not install concrete in the adjacent (but not connected) basement/crawl space. I asked Erickson to quote installation of plastic sheeting to seal that space. John, the sales manager’s quote doubled the total price. I already had found durable plastic sheeting for about $300. So how would that become $2000 extra? John explained that there would be a drainage mat under the plastic and it would be attached every few inches to the walls and then sealed with caulking. But besides sealing the area, the quote also included another extraction hole and piping to connect it to the fan. This seemed to me like over-kill for a 1200 square-foot house. But he said without the second extraction location, they would not warranty the job. So I accepted the “up-sell” and signed. Today the office called to tell me when the crew would arrive and they arrived on time and were very pleasant. However, they did not have the drainage mat. They called their supervisor and was told that it was not included in the quote and would be an additional charge. In fact it had been a verbal inclusion, not written. The crew was surprised that a second extraction hole was quoted, since the radon levels were not very high to start (3.8 and 5.4). So I feel that I accepted a possibly unnecessarily elaborate system, more elaborate than I probably really need, for twice the price. And didn’t receive the drainage mat that I was told would be part of it."

"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"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."

"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!"

"Very prompt, very professional, and shared a lot of information which I greatly appreciated. This is how it should be done, educate the homeowner and advise of what to know, what to learn and how to do work or why one would hire a professional to do the job. The inspector was going to follow up with some materials and contact information which I never received so that was a bit frustrating."

"Paul did an awesome job repairing my Victorian step cap chimneys. Communicated clearly, arrived when he said he would and left the job site clean. Price was very reasonable. I read the review from Mike O. and asked him about it. Apparently, there is another company with the same name in the Portland, Maine area and that review refers to that company. Will definately have him back to do more work on my stone foundation."

"In 1978 we purchased a house that was over 100 years old. The house had some settling issues, but I figured it must have finished settling after a 100 years - it wasn't. After shaving doors on a regular basis I tried jacking the house up. Despite my efforts the house continued settling and doors would stick again, especially in one corner of the house, so we hired a mason to replace that corner of the fieldstone foundation. He dug down deep removing a layer of peat and the installed a new steel re-enforced footing to put the new cinder block walls on. We did a stucco skim coat to match the existing foundation on the outside of the house and everything was good. For almost five years I didn't shave a door and I smiled every time I looked at that corner of the house. But after five years it started sinking again and it was worse than ever. This time I wanted someone that absolutely new how to handle the problem. I found Basement Systems of New Hampshire on Angie's List and had them come down to Melrose to take a look and give us an estimate. We received another estimate as well, but Basement Systems beat their price and really seemed to take an interest. <br /> I decided to hire them and actually made myself available to see the whole process. Four piers were installed over the course of two days. The first day two piers were installed on the inside of the house, down thru the basement floor and on the second day two piers were installed on the outside of the house. Jim Berube (the owner) the owner was there the second day. He took the time to explain the various steps that are required to lift the house. It was obvious that all my efforts had been a waste of time because the problem required much more technical knowledge than I ever imagined. The process is 95% prep work and when the lifting is finally done it's amazing. The foundation was lifted up slowly to where it was supposed to be and they controlled the lift by fractions of an inch. Jim had me check doors and windows and when I was satisfied he locked the piers in place. Now I know why they can guarantee their work for twenty-five years because after seeing the process I'm sure the corner of the house is not going anywhere! When they were finished lifting they patched up any spots that needed it and cleaned up the site inside and outside our house. The price of the job was very reasonable as well. <br /> Thank you Jim Berube and the folks of Basement Systems of New Hampshire for fixing that problem! <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.
