CustomPro LLC is a basement waterproofing and drainage business. In its Better Business Bureau profile, the company describes its work as gravity drain footing systems, landscape grading, concrete steps, crawl space insulation, structural repairs, foundation crack repair, septic and sump pump installation. A recent customer said George and his team installed a basement drainage system and stayed within the budget they quoted. A recent customer said the company installed a moat drainage system with a sump pump and battery backup, that the crew put up plastic sheeting throughout the basement to keep dust from spreading into the rest of the home, and that excavation, installation and finishing took about a week for a 2,200-square-foot home. A recent customer said George made quick work of a septic tank replacement and left the property with new grass growing. A recent customer who spoke with 5-6 companies said George spent considerable time educating them and gave them options and scenarios. A recent customer said this was the second project CustomPro did for them. A 2025 customer described needing an interior French drain installed in an 1800s farmhouse and said the crew cleaned up well when the job was done. A 2025 customer said that after a basement water leak, CustomPro came the very next morning and installed a drain beneath the front wall of the house, and that they never had that issue again. A 2025 customer said George drew up a plan for them to see before they committed, and that after three years of problems the basement had been dry since he completed his work. A 2025 customer said that when a bit of subsidence appeared under the driveway next to their new septic tank after excess rainfall, George was there within hours to fix the spot. A 2024 customer with a 5 ft crawl space said George came a number of times to work out a solution and completed the job as scheduled. A 2024 customer who is a landlord said the company did a crawlspace, sump pump install and drainage system without the landlord having to be present. A 2024 customer said that when water later appeared in another area of the basement, George arrived in less than an hour to take a look. Connecticut lists its home improvement contractor registration, HIC.0648908, as active, held by CustomPro LLC.
George and his team did an excellent job Installing a basement drainage system. They were prompt, always responsive, very professional, knowledgeable, and within budget of what they quoted. I highly recommend them as they were a pleasure to work with!
This is the second project CustomPro did for me and it came out great. They are very professional and always do high quality work. I highly recommend them.
My husband and I are extremely pleased with the work CustomPro Basements did in our basement. They installed a moat drainage system along with a sump pump and battery backup, and the quality of their work was excellent. The crew also put up plastic sheeting throughout the basement to protect our belongings and keep dust from spreading into the rest of our home, which we really appreciated. The entire project—including excavation, installation, and finishing—was completed in about a week for our 2,200-square-foot home. The team was professional, efficient, and respectful of our property throughout the process. We highly recommend CustomPro Basements to anyone dealing with water infiltration or moisture problems in their basement.
We had our septic tank replaced and George was fantastic. He made quick work of the extensive job and left my property in the best condition possible (new grass growing nicely). His price was more than fair and he answered the million questions I had, no sweat. Would highly recommend CustomPro.
We dreaded the thought of needing a system and spoke with 5-6 companies. George came out, spent considerable time educating us and between our own research and what we heard from multiple companies we knew he was knowledgeable. He gave us options and scenarios, and was very fair on price. Really happy with the quality of work done.
