Don’t waste you Money with Mancini. They do terrible work and not helpful at all once they are paid. The pool deck is supposed to be gray, it’s pink! The lines are crooked, they promised to fix it and never showed back up. They charged me over $40,000 to do this job and could care less that...

He worked hard to do the job successfully - installed a new filter and cleaned the pool - the pool is finally sparkling clean and the system is working. We were very pleased with his work. Enjoyed the pool for the first time this summer.

Jeff and his team replaced the liner on our pool. Jeff is very friendly and really knowledgeable. The job was done in a day and Jeff retuned the next day to do the final installation on our above ground pool. I would definitely recommend Blue Sea Pools and Spa.

Bruce and his team are very professionals, found the leaks for the pool, repaired them, resurfaced pool and did new pavers on the lanai. I would highly recommend this company for any pool projects. Trust worthy and always take your calls and fix any issues that I had. Very satisfied with...

The owners of the business did the install and were the consummate professionals. They did a great job and went over the care instructions patiently after a long day of work. My basement was left clean and the heat is working great!

"I typically do not deal with contractors as I do the majority of my home construction projects myself. Main reason for this is that I do not trust contractors and I feel there is the element of not getting the value for the money paid. Here's where Braz Masonry impressed me the most. Pool replastering is not something I would/could take on myself and therefore needed to get bids from different companies. Braz Masonry offered the best price and I decided to go with them, not only for the price but because I just got a good vibe from Roberto the owner. I was a little worried because I thought that, because of the lower quote, I would get hit with hidden extras to make up for the underbid estimate. The opposite actually happened. There was an unforeseen issue with my coping and there was an opportunity for him to make some extra money as I was already well into the project. Instead, I believed I got an extremely reasonable quote for this extra where I don’t think Roberto made any "

"Working with Raul at Diamond Pools was truly a five-star experience. We were away on vacation during much of the renovation, and Raul went above and beyond to send us detailed daily updates with photos and videos so we always knew exactly what was happening. He even added thoughtful touches we hadn’t requested, all as a courtesy, and still managed to finish the project in record time to meet the aggressive timeline I gave him. His professionalism, communication, and dedication to quality set him apart from anyone else in this industry. The results speak for themselves: our pool looks brand new, and our backyard has been completely transformed. Raul and his team didn’t just renovate—they left everything spotless, even washing every piece of patio furniture and the floor with soap so the area looked “newer than new.” The craftsmanship, care, and pride in their work exceeded every expectation. Don't look elsewhere, call Raul. "

FAQs for pool construction and installation projects in Mountainside, NJ
The average cost of an above-ground pool is between $1,100 and $5,700. Costs will vary depending on the type of pool you install. The low end of the price range includes a DIY kit for around $800 and goes up to about $15,000 for a custom pool with extra features like a deck and water features. Building an above-ground pool is much faster than installing an inground one. The cost tends to be much lower for an above-ground pool than for an inground pool because there’s less labor involved, especially when it comes to excavation and running plumbing and electrical lines.
Installing an inground pool costs around $55,000, on average. The typical price range is between $39,000 and $70,000, depending on the size and type of pool and accessibility of the site. This project requires an experienced pool installation contractor as the project usually involves extensive excavation, plumbing, electrical, concrete, and careful grading of the concrete or pavers around the pool.
Adding a spa to a pool is worth it if you use it enough. Adding a built-in spa to an inground pool can cost between $15,000 and $20,000, on top of installing the pool. A separate hot tub costs between $5,000 and $8,000. These prices will vary depending on the hot tub's size, type, and features. Additional costs include maintenance, electricity, and plumbing.
From start to finish, building an inground pool takes anywhere from two to four months. Factors that impact time to completion include any weather delays, material delays or shortages, scheduling conflicts, and any unforeseen challenges. The project may take most of the pool season, depending on where you live. Because of this, it’s a good idea to start getting estimates and finding a qualified pool company at least a year before your anticipated installation. Spring and summer is the busy season for pool contractors, which impacts their availability as projects are typically booked for several weeks if not months.
