"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"Excellent work from start to finish. On time initial evaluation and on time repair. Went the "extra mile" to repair additional small crack to ensure minimal water intrusion in foundation. Highly recommended and will use them again (if, that is, I need them :)"

"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."

"Rich gave me very important critical information over the phone to allow me to make a decision. He did not want renumeration. He gave me expert advice and a method to proceed. I learned about my concrete block basement and the reasons for the leaking. I can now approach the company that originally helped with the new construction for their help."

"* Work progressed exactly as Rene said it would, including building inspection, beginning and ending at the right times * Rene and Chris did a great job. I feel confident my house is in much better shape than it was before they came * Rene is the epitome of professional skill; I was impressed with his work, especially the attention to detail and his commitment to quality * Rene and Chris went above and beyond in their work NB: I have put foundation repair and general remodeling as Angi lacks a "sill" category."

"Ben responded almost immediately after Angie's List referred him to me. He came over the same day to provide an estimate, and was able to do the job within my time frame (which was a couple of days). He and his crew arrived promptly, performed the repair very efficiently, and did a really good job of cleaning up. He took away all of the broken up concrete and left things almost cleaner than when he started."

"My front stairs were a crumbling mess. A not so amazing job done previously by a not so talented contractor. Jim was easy to work with from proposal to final sign off. I am a no nonsense kind of person and my expectations are that a provider will deliver what they say they will. Jim and his team did that and more. The end result was better than I expected. If you want quality work, at a more than fair price with A+ customer service then then American Made is definitely who you want to hire."

"Masssave advised us of a mode issue in attic, and we contacted Baystate Mold Advisors for remediation solutions. Al came and did very thorough inspection. Al was knowledgeable and also very kind in sharing his knowledge without reservations. We learned quite a few things from him and also purchased one useful tool due to his sharing. The most practical solution Al provided require a replacement of the plywood which actually doesn't require their service. We thank Al for his knowledge sharing, and recommendation for a practical solution."

"Mr. Feliciano is very clear in his communication and takes great care in his work. He plans carefully, too. He addressed a foundation issue in my house. He left with a very high quality, expertly prepared solution. He meets his commitments and is easy to work with. He charges a fair price, too. I would easily work with him again."

FAQs for concrete foundation repair projects in Nashua, 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.
