We are accredited with the Better Business Bureau and maintain a consistent A+ rating. We offer quality basement & foundation work while providing outstanding service to each and every one of our customers. Basement Waterproofing Sump Pump System Crawl Space Repair Foundation Repair Concrete Leveling and Sealing Mold Problems.
"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."

"I wrote the C review. 3 years later, the windows leak every year and there is a leak in another room under the roofing that Sean "fixed." I have just learned that there are holes (where he put his scaffolding) above the leaking area. The windows were new and the only leaks are below the holes. I have spoken to other roofers who say it was a very poor job and should be redone."
