"I had Tim provide me with an estimate for tank and tankless water heater. Got the estimate and picked a tankless option only for the company to get mixed up and install the wrong device. After I informed Tim of the mixup, he was gracious enough to offer various options including removing the wrong device and installing the correct one. I didn’t think that was such a great idea. In the end, we reconciled and moved on. Mistakes happen but Tim rose to the occasion and fixed it. I would choose them to install a tankless water heater on my house again."

"Streamline Services is my go to place for plumbing and hvac repairs. I always have fantastic and speedy service. My last service call was truly exceptional and worth taking the time to review. I knew I needed my water heater replaced, and also a repair to my air conditioning system. I didn't feel pressured, and the technician answered every question I had, and I did not feel rushed into any decision. From the first phone call, to the time of install, I received nothing but great customer service. I won't call anyone else."

"Called ODP to come and give me an estimate for a repair of a main water line leak. Zach came out and priced out a couple of options from repair to replacement of the old line along with the risks of choosing one option over another. I went with the repair option. Zach and Eric came out quickly and had the repair completed in a few hours. I was very impressed with the quality of the repair, and they left the yard clean and with my wife's approval (not easy to get). The repair utilized really good quality materials so I have no doubt this leak is fixed! I will have no reservations in using these guys again."

"I called in the morning and Chris came out in the afternoon, when I was available. He explained and showed me what the problem was. He didn't have a new water heater on his truck so Tim came about 45 mins. to bring one. Installation was fast and Chris was very professional. They will be the first ones I call if I have any other issues."
