Fiberglass pools arrive as a finished shell, which can shorten installation, but the site must accommodate delivery, excavation, backfill, drainage and precise support.
Choose by usable dimensions
Marketing length is not the same as swim area. Compare waterline length, floor slope, steps, benches and depth transitions.
- Mock up the footprint
- Check entry and exit points
- Consider how the pool will be used
Delivery and crane access
The shell must reach the excavation safely. Trees, wires, narrow side yards and neighbouring property can affect the lift plan.
- Confirm route in writing
- Protect surfaces and landscaping
- Coordinate permits and traffic needs
Groundwater and backfill
Poor drainage or incorrect backfill can contribute to movement. The installation plan should address groundwater, sump access and manufacturer requirements.
- Ask who controls backfill quality
- Keep records and photos
- Understand empty-pool restrictions
Finish and warranty
Compare gelcoat terms, structural coverage, exclusions and the installer’s responsibility. A long headline warranty can still contain narrow conditions.
- Read transferability rules
- Document maintenance requirements
- Clarify who handles claims
