"Beware and be absolutely sure you ask them the right questions before the work begins. We were ignorant and trusting both big mistakes with these guys! "

"Timely and quality work"

"After meeting with Bob, and being shown and explained the project necessary to take care of our crawl space issue, I was convinced they were the guys for the job, They arrived when they said they would, and finished in the time estimated. A job well done and highly recommended !!!"

"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 a hostage. Even Air b and bs offer full refunds on deposits within just a few days of their arrival date. 3 days to cancel with service not scheduled for 6 weeks out, Come on 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 the 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 over 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 did not 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 nice enough. No answer. No callback. I will never seek out their services again and I will actively discourage others from doing so but, based on my experience, I expect they do not care."

"Kenson was very thorough and professional, and applied lots of experience to tailor their services to our exact needs."

"Thomas and Angelo (his crewman) were fantastic. (He had more crew, but Angelo was the only one whose name I knew.) They correctly diagnosed the problem (foundation cracks), sealed everything, installed a new sump pump and redid the flooring. They kept me informed every step of the way and started work within a day or two of hiring. The basement has remained dry as a bone ever since. One thing to note: They do require payment quickly (not all upfront but soon) and do not take credit cards."

"Great work, straightforward"

"Ronaldo will provide feedback which is nice. When I insisted that they leave the block edging where the new beds were added he expressed a couple times that he thought it would look better without, I eventually saw it and was glad he suggested it. His crew also added a cute little circular rock area when they extended the bed and some of the rocks weren't needed."

"We started having water leaks on a basement wall. Started slow but increased. We made the mistake of calling the big name TC H......, waited weeks to schedule first appointment. Finally showed up and proposed major excavation of basement wall, then applying new membrane. Unfortunately in our house, every external connection arrives via that wall. Talking electric, cable, septic, well water, and sprinkler. They wanted to use excavator to dig but wouldn't take responsibility for any potential damage. Price tag was very high. I was very nervous about this of course. I saw one source of water was around well pipe and other was wall itself. Contacted Marquis Well in Sanford who showed up immediately. Proposed hand digging at a lower price. They scheduled quickly, hand dug all the dirt, found Crack in water pipe casing and sealed up. But wall still had issue. Searched further and found Groundworks, lots of positive reviews. Called and they arrived quickly to assess. Beth is a true professional who knows her business extremely well. We signed proposal to inject sealant into cracks from inside of wall. Josh arrived to perform the work. He was effecient, very experienced who knew exactly what to do. During his inspection, he recommended bypassing one of the smaller Crack where water was never seen, thereby reducing our costs....unheard of! He completed the work quickly, zero mess or damage to our house. I cannot recommend both of these companies any higher. Both were outstanding in every aspect. Don't fall for the big ads from the others!"

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."
