Drainage Pro of CT puts in French drains, downspout extensions, drywells and catch basins for yards and basements that take on water. The company lists 14 towns in its service area, among them Clinton, Madison, Guilford, Branford and New Haven. A customer said the company installed a French drain along the back of their Madison home after years of basement seepage, and that in the first spring with the new system the basement is dry. A customer in Clinton said water pooled near the back patio in heavy rain until the company assessed the slope and installed underground downspout extensions; the yard stayed dry through the last storm. A customer with lawn erosion on a sloped part of the property said the company re-graded the area and put in a catch basin system. A customer said a puddle where they parked their cars was solved by underground downspout pipes and a drywell. A customer said the crew backfilled, graded and seeded so neatly that you barely knew they dug up a trench. A customer said the crew showed up at 8:00 AM as scheduled, finished the installation on time and walked them through the system before leaving. A customer said the on-site assessment was free and the work was backed with a 5-year warranty. A customer said the company installed trench drains in a commercial parking lot with no disruption to the business.
