"I have had the best experience with Gibraltar, and I cannot say enough about the people who work there and the product itself; we love our pool!! Itâ s given us a lot of joy this summer with friends and family. But foremost for my review is the people who I have interacted with since we purchased the pool in the summer of 2020- they are awesome. Really the best. I have not seen customer service like this at another company in a long time. We put in our new pool last November for a deeply meaningful reason for our family and I ended up talking with the CEO and shared with him the reason. He was so awesome and wrote me such a sincere, kind, and genuine note. From the CEO to the college kid on the floor and everyone in between- I have been so impressed with their patience, knowledge, friendliness, and professionalism. Iâ m so appreciative to Peter, Ellen, Grace, Ana, Jason, Keith, Jim, Ryan, Wayne and Jim. They have all been so incredibly awesome to deal with, and I feel like I am working more with a family than a huge company. Itâ s amazing they employee so many people who are each individually so helpful. You can tell the owners really care about how their store is represented and that they care about the quality of their work. We (like several other families) decided to build our pool during quarantine in 2020. There were delays that no one could have foreseen because the supplies were impossible to get for months- but that was no oneâ s fault, no one could have guessed we would be in a pandemic, and that the demand for pools would go up so much. So, even though there were delays, we understood, and Gibraltar did everything the could to get our pool built as quickly as possible and to make sure it was open for the summer season of 2021- and it was. I was sad to see reviews that said they took too long- I honestly just donâ t think it was fair. Who could have foreseen the impacts of a pandemic? So, for us, the delays were what they were, and we appreciated that they did all they could, with what they had to work with, and kept up updated along the way. I would highly recommend Gibraltar to anyone who wanted to put in an awesome above ground pool and have superior customer service."

"Lou, Andrew and Lordes were amazing people to work with. We would highly recommend Ranieri Construction to anyone needing pool or decking work. We feel our pool is all set now...better than new!!!! Everyone remarks how nice it looks. Ranieri Construction went above board to meet our needs. They were prompt, always here when they said they would be and continually kept us in the loop of what they were doing and why they were doing it."

*******20 YEARS EXPERIENCE******* \nBeginning in 1987 when I built my first swimming pool as a laborer, I fell in love with the job, I was so proud how it made the customers so happy and the children glowing with anticipation. I worked on a few different crews with different companies through the years and I really wasn't happy with the way things where going. I was losing my pride, we where pushed to build as many pools as we could and the quality of the work wasn't as important to the big guy, as hurrying to the next job. I was not satisfied with the way things where done. \n \n After working on a few thousand pools I decided to change things in order to bring pride back to pool installing. I got together with a friend that felt the same as I and we went out on our own. We may have only built 1 pool a day, instead of 3, but we where proud. The pools are installed the way they should be, like it was our own. In the next two years we only built around 300 pools, but every one made us proud and not once have we had a complaint. \n \n 19 years from my first pool, April 2006 starts the best year ever; our first year as Poolinstallers.net a family owned and operated business. We do carry a $3,000,000 insurance policy but most of all we carry the pride that every pool we install will add to our outstanding record of quality workmanship, within an inch isn't good enough for us, its got to be perfect . \n \n If you're looking for a top quality, professional pool installation at an affordable price, Poolinstallers.net is the company for you! \n

Install Above Ground Pools FAQs, answered by experts

The local climate creates a short window for pool construction and installation. The ground in MA stays frozen through early spring, restricting excavation to warmer months. Deep frost lines require special plumbing and footing designs to prevent structural damage. Additionally, average annual snowfall exceeds 70 inches, meaning you must install heavy-duty covers rated for significant snow loads to protect the structure during the long winter.

Helpful?

When hiring local professionals for pool construction and installation, verify they hold active state registrations and carry liability insurance. Choose contractors with specific experience navigating Williamstown's rocky, clay-heavy glacial soils and deep frost requirements. Ensure they understand local zoning bylaws, especially setback rules near wetlands, and confirm they will build fencing that complies with strict state safety codes to keep your property secure.

Helpful?

Following pool construction and installation, schedule final structural and electrical safety inspections with local officials. Update your homeowner's insurance policy to include the new structure. Because the MA swimming season is short, establish a strict winterization plan before mid-October to prevent freeze damage to new equipment. After the first spring thaw, inspect the surrounding deck and drainage channels for any shifting caused by frost heave.

Helpful?

After completing pool construction and installation, prepare for Williamstown's heavy snowfall and deep freezes. You must fully drain water below the skimmer lines, blow out plumbing, and plug the pipes before winter. In the fall, skim the heavy leaf drop frequently. When spring arrives, inspect the pool shell and decking for any cracking caused by freeze-thaw cycles, and test the water chemistry to balance out snowmelt dilution.

Helpful?

To protect your investment after pool construction and installation, keep tools suited for Williamstown's cold climate. You need an air compressor to blow out plumbing lines and expansion plugs for deep freezes. Keep snow removal tools nearby to clear heavy accumulation off your cover. Additionally, stock fine-mesh leaf nets for autumn debris and a digital water testing kit calibrated to measure local mineral profiles.
