Trustindex verifies that the original source of the review is Google. John Lapan, his son and the entire crew did an amazing job installing a full perimeter drainage system and sump pump inside our basement. They are a very hard working, professional and talented crew. Johns communication skills are excellent and kept us updated with the progress, and any obstacles they had to overcome, which they did each time. I’m confident our basement water problems are a thing of the past. I highly recommend Lapans Basement Waterproofing.Kevin Tanguay2025-06-09Trustindex verifies that the original source of the review is Google. John and his son went above and beyond!

Th This remarkable business also offers and unbeatable 25 year warranty. Their prices are fair, and they will work hard to make sure your basement stays free of water!!Amoria Brown2025-03-28Trustindex verifies that the original source of the review is Google. John Lapan and his family business are amazing. Years ago we had a major water problem in our basement. They came in and put a drain system in just a week. They were neat and professional. They cleaned up every night so u could barely tell they were there. They also did a few other things to solve the problem as well and we have never had an issue since. Last year I needed a bulkhead put on my house. I never had basement access from the outside. John and his son were fantastic and the system they used to install and build it was amazing. We have them come every year to clean the drains and the pumps and it is so worth it. They actually pull the pumps and scrub them clean and make sure they work correctly. I 100% recommend them to anyone.

Him and his son were professional and courteous, they took their time making sure they did it right and were thorough to make sure my aunt and uncle knew what was going on every step of the way. 100% recommend for anyone with basement water issues”Shannon Luna2025-03-20Trustindex verifies that the original source of the review is Google. Had a stressful flooding situation where water was coming through a basement window during heavy rain — John was able to come out quickly to assess the issue, offered a very reasonably priced, simple solution, and was able to complete the job before we went out of town on vacation. His son did a great job installing the window well and is super nice and friendly! My husband and I are always happy to find an honest, trustworthy contractor and Lapans definitely fits the bill. Hopefully we don’t have more water issues but if we do, we’ll be calling Lapans.Katherine Mirani2024-09-18Trustindex verifies that the original source of the review is Google.
