"I strongly caution anyone considering doing business with this company. I gave them a deposit of $4,428.65, and when I canceled a week later they kept almost $900 of it even though my service was not for another 6 weeks. You do sign a very simple, clearly stated document that says, “Should you cancel beyond three business days, you understand your deposit is non-refundable. Northern Basements may choose to refund depending on cancellation circumstances.” I fully acknowledge that I canceled a few days outside that window, but I hoped an honest company that cares about customers and referrals would choose to provide a full refund. I am a sucker for hoping that. They chose to risk my impression, referral and review for $885.53. If nothing else comes out of this, I hope everyone reading at least goes in knowing that this statement on their contract is a real threat and your deposit is hostage. Even Airbnb’s offer full refunds on deposits within just a few days of people’s arrival date. 3 days to cancel with service not scheduled for 6 weeks out, “C’mon man.” No materials were used. No service workers’ time was taken. The manager justified the 20% withholding as credit card fees, restocking fees, time and resources for the estimate, and administrative fees. I wholly accepted responsibility for the credit card fees and time of Paul, the gentleman who performed the assessment, and I offered to settle at 10%. I still believe any reputable company would have provided a full refund at this point in a project, or at most deduct the credit card fees, because nothing more went into this beyond what would have normally been a free estimate. The further arguments the manager made for the additional fees were the scheduling of their team and allocation of materials for my project. Complete nonsense, especially when the project was not set for 6 weeks away. Because they had my deposit hostage, they had control of how much they decided they wanted to keep, it was completely arbitrary, and they kept almost $900 of my money without providing anything. If they wanted to cover their credit card transaction fees, fine, at most 6%, but the rest is absolute robbery. The only solace I can find in this loss of almost $900 now is that I didn’t spend another $13,000 with them. I tried to call Paul after speaking with the manager to ask if he could do me a favor and try to reason with the manager on my behalf because he seemed like a nice enough guy. No answer. No call back. I will never seek out this company’s services again and I will actively discourage others from doing so but, based on my experience, I expect they really don’t care."

"The team that was sent smelled of weed, first thing I noticed. The work was done quickly, so that was good, but they didn't get an in process inspection and instead sent over an inspector more than a month after the work was done. The dirt that was displaced is just all over my yard now, and I have a bunch of big holes where they didn't pack any dirt. The company offered to fill them but I never heard back after that offer. As part of the work, they dug around the chimney, and it appears they caused it to break. They claim no damage was done, but I'm finding many pieces of concrete and brick strewn over my yard."

"They did a fantastic job! We have had driving rain since the installation and our basement is bone dry. They came on time, were very polite and I'm very happy with the fast train system they installed."

"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."

"I requested a quote by email, clearly specifying it was for 2 cracks and sending 4 pictures (2 from the inside, 2 outside) as requested. One crack was twice as long as the other one, very different and salt leftover from water infiltration. I received a quote for $500 which detailed the total cost, without any mention of additional costs. After the technician performed the work in less than 30 minutes, trouble started: he told me he was directed to work on just one, not two foundation cracks. I received a call from the same woman that set everything and she first stated I only request a quote for a crack: I went back to the email and it clearly stated "quote for 2 cracks", she claimed she got confused by the pictures and thought I sent the same crack from different angles. Honestly, they are in the crack business, I don't know how one could get confused by this. She insisted that, despite her making a mistake, I'd need to pay more. I got a call from the owner which argued with me about paying $350 more, that the quotes I got from other companies were also about a single crack, that their quote has different pricing per crack (I verified, it did not, there was just a single price). After I mentioned this seemed to me a bait and switch technique, he argued some more but in the end agreed to accept the quoted price."

"Barn Rescue – My barn was hit by a vehicle, which broke a large post and pushed section of siding out from under the roofline, plus major damage at ground level. Brad shored it up for the winter with an array of jacks and an enormous chain to ensure the thing wouldn’t fall down till they could return in the spring. Come spring, they fully replaced the damaged section’s support members and facade, and added bracing to the attic, rendering it stronger than before. Foundation support: The sagging beams and jerry-rigged support columns in the dirt basement of our 18th century house were inadequate. They dug and poured a dozen footings and lally columns, supporting a line of new 6x6 and 9x9 beams that provide solid support to the house above. They showed up promptly every day, worked fast, and left the site clean and finished. Both Brad and Chad have a deep knowledge about old houses and the techniques that were used, and I felt my historic register property was in good hands."

"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!"

FAQs for concrete foundation repair projects in Gilmanton, 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.
