"Very professional, friendly, clean and fast. He even fixed some bad plumbing the original installer had put in, without charging or complaining. Price was what he quoted plus a few hoses and valves that had to be replaced. Would definitely hire again."

"This was the first time I used D-Tech Systems. I needed an electrician to reinstall a chandelier. Daniel Malachowski (with D-Tech Systems) was polite, extremely efficient, very conscientious about keeping the work area clean, and did a professional job in a short timeframe. During that same visit, he was able to resolve a couple of other electrical items and showed me how I could fix a simple item myself. I will use D-Tech Systems in the future and would definitely recommend them and, in particular, Daniel M."
