The Technician was a man with a plan and followed through to completion most efficiently! Thank you for awesome service. 9/1/26 The technician replaced bathroom drain fixture, overflow component and pop up. In addition, the faucet pop-up component was replaced with high-grade material.

We had an issue with what looked like a tiny drip in the basement, but Nathan who was amazing (friendly, caring and very professional) spent the necessary time checking out all the area. He found a bird had built a nest in the dryer outside vent causing this crazy scenario. He found it and fixed it that same day. 100% satisfied from this service. We recently had Jason come out and look at our flickering light in the basement staircase. Jason was just as professional, friendly and knowledgeable as Nathan. Haller hires some great technicians. He replaced the fixture with one we provided and did a great job. Very satisfied.
