Pool Builders in Durham Region

The pool price is rarely the project price. Decking, fencing, landscaping repair, electrical, gas for a heater, and water are frequently quoted separately or omitted entirely. Ask for a total installed cost including everything required to legally use the pool, then compare.

Questions to ask before you hire

What is the total installed cost including electrical, gas, decking, fencing and landscape restoration?

Who pulls the enclosure permit, and when must the fence be up relative to excavation?

Which licensed electrical contractor are you using, and will I receive the ESA Certificate of Acceptance?

What is the realistic installation window, and what happens if it slips past the season?

How is my deposit protected, and what is refundable if you cannot start?

What is the warranty on the shell, the liner and the workmanship - separately?

What restoration of the yard is included after excavation equipment leaves?

What will this cost me annually to run - chemicals, heating, electricity, opening and closing?
