"We're so glad that we went with Hancock for the job! It's been wonderful to be able to stretch out into the new space. Bedtime for the kids has been going so much better now that they have their own rooms and we love how the rest of the spaces turned out. We've very much appreciated the consideration that Darrell, Kevin, and the team have had with helping to accommodate the family living in half of the house while the project was going on. That was really the only way that we could have afforded the project. I'm definitely still amazed that it was able to be done in the short span of time. Even our dog is in love with her expanded domain. Throughout our addition process, we've been really pleased with the progress, the flexibility, and the quality of work that the whole Hancock team provided in working with us, with our architect, and with our structural engineer. We would not hesitate to recommend Darrell and Hancock to anyone else who is considering a project in the area. We've had several folks in the neighborhood on their daily walks stop by with positive comments and admiring the progress or let us know that they were also going to embark on a project with Darrell given how great it's turned out at our house and how quickly the project was able to get completed. We love the results and have been using all of the new space already! Thank you to Hancock Building Associates for making everything work out!"

FAQs for sewer main install, replace or repair projects in Cambridge, MA

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
