"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."

"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."

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

"Rene is the best! We reached out to Rene about structural issues on our old home. He responded promptly and scheduled a visit within a few days. He knew just what to do to address some sagging floors and areas of the house that weren't correctly supported. He did all the work himself (he sometimes has his son work with him). I have no idea how he was able to complete all the work on his own, especially pouring new concrete footings in a very small crawl space! He is a machine!!! He is meticulous in his work and really goes above and beyond. He left our basement cleaner than when he started!!! He’s a super nice man and it was a pleasure having him work on our house."

"run for your life. This guy is completely unprofessional. He pitched it towards my house and now I have major water problems. He forgot to put stairs in. He refuses to fix anything and told me he is done doing business with me. He left the job completely unfinished. do not hire this company, I don’t know how this guy is still in business"
