"Found this company from someone's recommendation, now really bad recommendation! Anyway, had sinks backing up - something plugged some place. I was actually out of town, so wife dealing with this situation. Date was August 15, 2018. 1st guy came out, looked good, but next day same situation. A very GOOD tech came out who fixed it, we thought. No issue with them coming back out - which was good. Then on 11/5 had new town water meter installed. After install, need to run water from upstairs tub/shower. After a few minutes while I was down in the cellar, water starts coming through the celling! Run upstairs and sinks on 1st floor were overflowing. Shutoff tub, call Mill Town. So for 3rd time they came right out (again good) - asked for same good tech, got him. He fixed, best he could but (this time) put blame on some drain pipe in cellar being too small? They did not charge extra, but said this was last free time for this issue. For this service original date was 8/15/18 and 8/16/18 and wife was charged $287.50. Not sure fair or bad price. So now we are going to have both gas range and dishwasher replaced. Call Mill Town to assist, and also asked for insinkerator (garbage disposal) install, as we had recently changed from septic to in-town sewer. Date was scheduled for afternoon of Wed 11/14, as that was the window Home Depot stated for delivery. Monday AM find that HD will delivery around 11/noon and Mill Town could not come earlier, so had to reschedule. 11/23 was Mill Town first open date. This time scheduled them for AM. Of course this time HD schedules the appliance delivery for 11-3, which I only find out about the night before. Mill Town arrived on-time around 9, un-hooked old range and dishwasher, added new connector for gas, and then installed 1/2 HP garbage disposal, Badger 5. Finished this around Noon, and we are still waiting for HD delivery with no real good info from them. Tech took lunch, and then had to leave, which I understand. Said they would come back to finish. Paid them $1602.60 for install of Garbage Disposal, with new unit (electric already there) and un-hook dishwasher and range, Here maybe 4 hours, even at $200 for equipment, that is $300+/hr??? HD was delayed with appliances (trunk broke down) and actually did not arrive until 5:30 PM. In 15 minutes appliances in house and old removed. Call Mill Town around 5 PM (Friday night) to say appliances would be delivered in next 30 minutes, for which they said if they came out then would be after hour rate. Told to call them back tomorrow. Called them on Sat AM, they said they would try and would contact me back. Never heard from them. Called them back Sat afternoon, told me to call them back Monday AM. Said I wanted to talk to Service Manager, was told they would tell him to call me. Called again Monday AM, said they would put me on stand-by. Why I was not there already after Friday evening and multiple calls on Sat, who knows?? They would call me if they had any openings. Now this is for job I already [over?] paid for. Also on Sunday evening wife was using sink, and with new garbage disposal install, sink was leaking. Turns out no plug in the hook-up for dishwasher, which was not yet installed! Told them this on Sat, still on standby. During day on Monday called them multiple times, same story on standby. Was told later in afternoon (too late) that they had called me 4 times, had tech available, but since no answer they sent him elsewhere. My iPhone showed no messages or no incoming calls, nor did my home phone which has Verizon Fios call screening and mailbox, which sends me an email for any left messages. Again request call from Service Manager - said he would call me Tuesday AM. Now Tuesday evening and no call from either Mill Town or Service Manager. I have at this point in time contact another plumber to try and get some one out. Hopefully someone from another company will be here on Thursday. By then almost a week with no range, no dishwasher and a leaking sink. I have placed a hold on check payment to Mill Town. This is the only thing that I am 100% sure I will get a call back from them about. DO NOT USE THIS COMPANY!! Follow-on - now Tuesday 11/28. I got a friend to help me get a plumber today - Powderly from Billerica (978-663-0164). They came out this AM and finished all to PERFECTION. At least now I have a plumber to call and trust. Cost to me was $275. They said for what I had previously done, probably no more than $200. So total should have been no higher than $600 (on high side), not $1602.60!!! Then perfect timing. No more than 15 minutes after Powderly finishes and leaves, guess who calls? Yes Mill Town, and they think Service Manager had already called and spoken to me, which of course never happened. I am sure the only call I'll receive from Mill Town will be about payment, and maybe this review!"

"torn between 2 &4 stars but went with 2 only because I feel the cost exceeded in my opinion a reasonable cost to replace with a basic 40-gallon electric hot water heater based on the cost I paid two months ago to have a new eclectic 70-gallon high efficiency heat pump water heater and expansion tank installed. We had no time to shop around.... 4 stars for the prompt repair and 2 stars on the pricing."

Septic tank services FAQs
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
