Awesome Service
Charles - Duluth, GA
Today Gavin Torres of TE Certified replaced my leaking InSinkARator. He was super friendly, provided me several options, had the replacements on the truck and was done very quickly. When he left, everything was cleaner than when he arrived. Gavin was able to have an enjoyable conversation with me about baseball while he worked. Also, the estimate and outdoor the price was very reasonable. I will continue to call TE for my needs.
