At MillTown Plumbing, Heating, AC, Drain Cleaning & Electrical, we know the value of prompt, professional and reliable services and look forward to serving your needs in the Merrimack Valley. We're a same day/next day service company offering quality work and unbeatable service.

"I used to like them. Use them for my big install of backup basement sump pump. This time, I was out of the country, my rental property in MA needs a toilet fix. It was a standard water tank leak and we need to replace the inside mechanism. Milltown came and said 'rebulid the toilet', my wife authorize them to do it as I was not reachable at the time their plumber was at the rental property. They were in and out according to my tenant for at most 45 min, rebuilding two toilet tank and fixed the leak. The bill came to be 1200, $600 a toilet. One line item on the receipt is $470 for the kit they use to replace the plastic mechanism inside the water tank. I casually google the kit, I can get a universal sup kit for the toilet to replace that for $20. I called them, manager came on gave me that talk - we did hundreds of toilet leak and we average all of them to come up with the cost for that line item, which includes (a) parts (b) labor (c) our service guarantee for a prompt and reliable service Say they charge $200 /hr labor, 1 hr for two toilet is $100 labor for 1 toilet (remember, the plumber was there like 30-45 min rebuilding the two toilet). Say total parts are $100 (with markup), we are talking about $200 for fixing the leak of 1 toilet. They charged almost $600 for one toilet. You can do that math. I expect some up charge, but I am not paying $300 just for getting prompt reliable service. I turned around and asked for a few reliable plumber quote from Thumbstack with great reviews, most can do the job for $200 labor and I can get them the universal kit they will be able to come on the same day. So maybe if you want Milltown to do bigger job, that is ok. For smaller job, it does not worth it. Replacing the toilet flush mechanism is really not rocket science in plumbing. If I am not thousands of miles away, I would have done it myself after watching some Youtube video. I am willing to pay up charge for the service, but this is really above and beyond the normal up charge range, $1200 for a 30 min job replacing the toilet flushing mechanism in the water tank!!"
