In a 2023 Google review, a homeowner described the basement and foundation projects Dan and his team did for them. In that 2023 review, the first project was waterproofing a very old basement, which involved repointing walls and support columns, filling gaps and holes around windows, and redoing the entire floor. The same 2023 review says they next demolished a door into the basement and created a brand new bulkhead to fit under the homeowner's plans for a new deck. Finally, per that 2023 review, they repointed the entire foundation outside and put in underground drainage piping all around the house to pull water away to dry wells. The 2023 reviewer called the work high quality, said Dan and his team were efficient and finished ahead of the estimated timeline, and said they answered every question and checked in at every step. That 2023 reviewer also wrote that their quote was the best of multiple quotes on price, timeline and attention to detail, and that when they weren't the experts for a job, they came with recommendations for other contractors.
Dan and his team were fantastic in every way! High quality work, very friendly people, efficient, and even finished ahead of estimated timeline. They answered all of my questions and checked in with me at every step of the process. We are extremely happy with the end result of each project they did for us. First project was waterproofing our (very old) basement, which involved repointing walls and support columns, filling in all gaps/holes around windows, and redoing the entire floor. Next, they demolished a door into the basement and created a brand new bulkhead that will fit under our plans for a new deck. Finally, they repointed the entire foundation outside and put in underground drainage piping (akin to French drains but without the pump) all around our house to pull water away to dry wells, ensuring the basement will really stay dry. If I could give these guys more than 5 stars, I absolutely would! We had multiple quotes for this work, and theirs was the best in terms of price, timeline, and attention to detail. We are already planning another project with them because we are so happy with their work. 10/10 recommended Dan and his team for any job you throw at them. If they aren’t the experts for the job, they come with recommendations for other contractors, too!
