"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"I can’t recommend Tuck’s Waterproofing highly enough. They repaired two foundation wall cracks externally and put in a second sump pit with a battery backup for us. Throughout the process Tucker was extremely professional, very knowledgeable, patient in answering all of my questions, responsive (he came out twice to assess to assess, answer my questions, and provide a quote before beginning work), clean, and truly went beyond the scope of work to proactively address any other issues he saw. That is such a differentiator in my mind: he saw the primary sump pump line was cracked on the exterior pointed it out and and fixed it for no additional cost; when putting the dirt back for the external crack repair, he noticed the initial grading wasn’t great so he proactively graded for us; he also cut out a partially clogged pop-up line and replaced it with a new one rather than simply tying the new sump line into a poor one. His price was also very competitive relative to two other providers. I feel confident that if any issues were to arise going forward that Tucker would partner to address because his integrity is so apparent. It’s been a month and several rains since and our basement issues are clearly completely remediated. Ultimately we were so pleased with the entire experience and would highly recommend Tucker for water remediation issues. His crew left our basement cleaner than they found it, and we have literally nothing but positives so say about the entire experience."

"A Waterproofing Solution did an over the top job. The workers arrived on time, did the job and cleaned up af the end of each day. The men who came out in the beginning of this project were very prepared, explained the process and offered Veteran’s discount. They also explained how to get financing if needed. There were several heavy rains since the drain and pump were installed and the basement remained dry. Such a relief. Highly recommend this company. We had 5 estimates and chose A Waterproofing Solutions. We made the fight choice."
