“Impeccable craftsmanship, excellent communication, quickly handled unexpected issues, inspections, weather, and my own design changes with spectacular results. Willingness to provide advice and services beyond the scope of the original proposal. The whole crew was professional and friendly. I got several equivalent quotes, but can’t imagine anyone else providing such a relaxed, responsive and overall excellent experience.” – Greg, Apex, NCĀ  2/24/14

“COMPLETELY SOLVED OUR DRAINAGE PROBLEM and occasional basement leaks!
The Drain Designs team built two French drains, one catch basin, and tied all gutters into their superior commerical- grade PVC piping system such that all rainwater is carried away from our house … We no longer have any issues! I contacted several drainage services, but was most impressed with Drain Designs. Furthermore, I was so impressed with the solution and team, that I had them connect all downspouts to their system!” – Michael, Cary, NC 10/21/14

“From the initial contact… to the very end of this huge project, we could not have been more pleased.

As a licensed Professional Engineer, I provide consulting services for Kevin when he and/or his clients want an engineering perspective in reviewing problems and identifying alternative solutions. It has been my experience that Drain Designs LLC and Kevin Kondas provide a high level of client service backed by quality workmanship. I have no reservations about recommending Drain Designs for the analysis and repair of drainage related problems associated with residential and commercial properties.
