This is a tricky pool to install a cover on and it takes a lot of time and skill.
When considering prices, you have to look at a variety of factors.
1) Pool shape, size and weight?
2) Is the cover a standard premade size or freeform custom?
3) Web spacing?
4) Deck type?
5) Cutouts?
6) Raised wall treatments?
7) Hammerdrill or diamond bit hole saw?
8) Cover material (Mesh, dense mesh or solid)?
Installers should provide you with quality standards such as:
1) Making sure that the overlap is equal everywhere to specific tolerances.
2) The tension is correct at all springs (Not too tight, not too loose and just right).
3) The straps are all straight +/_ specific degrees of tolerance.
4) The holes are smooth and avoid chipping, spalling or other deck damage as much as possible.
5) The straps are all adjusted to a good length in the middle of the range and not too short or too long.
6) The springs are all centered in the middle of the vinyl spring guards.
7) No damage to the cover during installation (nicks, cuts, scratches, punctures etc.).
