"After 2 1/2 years of not being able to secure a contractor willing to excavate or property we found Joe who told us, "No problem when do you want to start?" After receiving Joes quote we asked if he could build us a wall also. Joe stuck with us even after we were satisfied with the excavation. He encouraged to order gravel late on a Friday to finish up the site."

SSG, or South Shore Gunite Pools, is New England's largest pool builder. We offer building, renovation and maintenance services to residential and commercial clients throughout New England. Headquartered in North Billerica MA, we have been setting the standard for gunite construction and quality swimming pools since 1975. We are shockingly unique in the way that we build, eliminating the uncertainty of relying upon subcontractors and operating with fully in-house employees. This strategy allows us to take full responsibility for our client's projects.

"Hired this company for summer 2019 to open/close and clean weekly. In the month we used SSG, the pool was not cleaned properly once. 25 tiles were damaged mysteriously upon open, there were leaves and dirt left in the pool the entire time and we have not been able to use the pool yet. We expressed our disappointment and gave them more than enough chances to rectify things. They didn't. Pictures attached are from our pool and spa today - after the tech "cleaned" and left a bill for over $200. Absolutely horrible. Terminated contract."

Earthquake Retrofitting questions, answered by experts

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.

Projects will vary based on size and scope, but an average earthquake retrofit takes between two weeks and two months. This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.

Some cities or states may require you to have an earthquake gas shut-off valve. Your insurance provider may also have requirements for installing this valve. Even if you don’t have to have one by law, it’s wise to have a natural gas plumber install one anyway. These devices can be lifesaving and prevent fires or explosions in the event of a gas leak.

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Costs vary as much as timelines. The average earthquake retrofit costs between $3,500 and $8,700. However, homes on hillsides, large homes, and those with rooms over garages can cost up to $12,000 or more. Make sure to get a few estimates to compare the cost and services.
