I had a sump pump in a window well that was not discharging far enough from the window well. Design Exteriors tied the sump pump discharge and two downspouts into an underground drainage system that drains in a better location. Sonny walked me through his recommendation and provided a very detailed quote. I was very excited that Design Exteriors did this type of work (I couldn't find any other non-plumbing contractors who did this) and that Design Exteriors (and Sonny) appeared to have a lot of experience and to know what they were doing. Sonny's team was very professional and did a great job. I am very pleased with the finished product.
