FAQs for pool construction and installation projects in Marathon, NY
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.
