He just pulled out the old pipe and slid in the new one with disturbing the lawn or walkway, they fixed the sidewalk and swept up. Very efficient."

We are a locally owned and operated company. We value honesty and integrity in all aspects of our business. We offer a variety of home improvement services that are customized to each individual project. We pride ourselves on the quality of our work, as well as our commitment to outstanding results. We look forward to building lasting relationships with our clients and guarantee your satisfaction!

"My house is on a little bit of a hill. Over the years, the retaining wall and brick columns lean out. I had just asked Franky to push it all back and repair the brick columns. This was incredibly difficult because of a concrete slab in one section and a large chunk of concrete attached to the bottom of the wall in another section. He had to repeatedly pushed and pushed on this wall until it was in the original position. After that, he drilled holes in the walls, the brick columns and the slabs, then inserted rebar and poured concrete to tie it all together. This was not part of what I asked him to do, but now, thanks to his hard work, this wall is probably 10 times stronger than it's ever been. In addition to that, in our sweeping up the area each day, I had pointed out a section of the sidewalk where one section was sticking up about an inch higher than the other, creating a big trip hazard. This was the city's responsibility, yet he took the time to do a very professional repair that I'm sure the city would be very impressed by. As I mentioned, this is one of the hardest working guys I've seen. You won't be disappointed by his work."

"I was massively overcharged. I called about low water pressure. I have well water and figured it was sediment or mineral buildup. Told them that on the phone. They installed a $44.00 part form Home Depo in less than 30 min and charged $645.00! When I asked how much it was for the part and how much for labor, he refused to itemize the bill. He asked me questions about where I worked before writing the bill. He said I was paying for his truck being filled with parts. I am not paying for him to be in business. I am disputing the charges."

FAQs for septic tank service projects in Watertown, MA

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.
