"I would thank them for the work and services. Max was very prompt and polite. We were definitely taken aback with the bill. We were not informed about any of the charges around: 1. Time taken for pulling the permit(1hour@$180) 2. Time for inspector coming in(1hour@$180) 3. Price for permit These 3 costs total to $425. The material cost of $263 definitely seemed marked up. * I wish they had mentioned about expecting these costs so that we could make an informed decision. * We have had several permits pulled in last year ( had frozen pipe burst situation so had renovations going on for multiple months) and never were charged for the time taken to pull permit or for inspectors time at the time of inspection. * Max mentioned it was going to be $180 an hour and you were here for 2 hours from start to end.. The father(Peter) kept mentioning about the emergency charges that there are plumbers that charge $300 an hour, I was clear that we were okay with waiting for a couple of days so there was no question of those charges being applied. He kept giving an explanation of the bill being high enough but it seemed very vague. We were charge $1100 for 2 hours of work to fix a slow gas leak that National grid had identified and pointed to us so they shut of our gas supply. National grid guys had told us that it would be only 1-2 hours of plumbing work. I would not recommend them for sure for the sour taste it has left for us. I wish we went with presidential plumbing or 128 plumbing that we have gone in the past. They are expensive but you know the quote before hand."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."

"What I thought would be a simple snaking turned out to be a month long adventure working alongside James (owner) and John at Mac Home Services. Mac Home was excellent. Immediately addressed any issues, worked steadily (even through the holidays!) to resolve pressing plumbing issues, kept me well up to date, were very reasonably priced all things considered. I would absolutely use them again for any plumbing issues. I can't say enough good things about the experience overall. My house was built in the late 1800s and ad-hoc added on to over the years with varying degrees of professional work and Mac work well to fix it all. I never felt like they were having me on (as a young-ish woman owner) or upselling me on anything."
