Matt PicardJohn, Jimmy, and their team installed a French drain and new well/pump/discharge line in my basement. They were a pleasure to work with, going above and beyond to explain the work while being transparent about pricing and any hurdles encountered during the job. The system is rock solid and I no longer will have any anxiety when we get ample groundwater and/or rain. I cannot recommend them enough.Trustindex verifies that the original source of the review is Google.

Joseph StearnsJohn 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. Joe Stearns, very satisfied customer.Trustindex verifies that the original source of the review is Google. Shannon Luna“This company was great, John Lapan clearly knew what he was talking about and solved my aunts problems for thousands of dollars less than the other companies we had give us quotes. 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”Trustindex verifies that the original source of the review is Google.
