Our tankless water heater installation had some hiccups, but our plumber Armando was very professional. I rated the price lower because the estimator was very far off on the total price from what it ended up costing us (the budget was blown by about 40%). We had to do a lot of digging in our yard as well, which we did not anticipate. However, Armando stayed at our house every night until 8 PM or 9 PM, and did his best to get the job completed timely. We still have outstanding work to complete, but I am confident Baker Brothers will get everything wrapped up. Thankfully, I had someone that could be at my house while I was at work, so the extra timeline did not hurt too much. We do have exposed piping in our garage that we are not thrilled with, but this was an error with the estimator that came to do the initial projection of the hot water heater install. I ranked the quality slightly lower because we were not told in advance of this, so we were a little disappointed. Overall, I thought the plumber doing the install did a great job, and I would hire Baker Brothers again. However, I hope in the future our estimates are closer to our final costs and that the final work product is more in line with projections.
