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.

An earthquake retrofit is essential for safety in an earthquake-prone area. Without proper retrofitting, your home is at risk of sliding off the foundation, shifting, or collapsing.

You may also require a retrofit if your home was built before 1980 when building codes began requiring reinforcing, bracing, and bolting for new construction. You may not be eligible for insurance to help pay for earthquake-related damages without a retrofit.

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.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.
