I had to replace my rented water heater and I opted to buy it this time. After sending pictures, Mike responded quickly with a quote and detailed explanation of the process. On the day of installation, he called to confirm the technician’s name and confirmed the drop off of my old unit. After the installation, he followed up. This type of professionalism is hard to find these days and I sincerely appreciated the straightforward approach. The technician Ehsan was amazing as well, kept everything safe and tidy. I highly recommend DeMarkHome, Mike and Ehsan. Now I have someone reliable to call in case of need.

I’d like to say thank to Mike and his team on their amazing job. I just requested a quote for the tankless water heater in the morning and the installation was done same day. Verry satisfied with new machine. Best service ever

Mike was extremely patient with me as I considered my options for a combi boiler. He explained things in a way I could understand. Ehsan and his co-worker were professional, competent, hardworking and respectful. They went above and beyond to make sure my in-floor heating was working and took the old tank away. I’ve only had the system for a day but so far so good.
