Trish, welcome to the forum!

The red flag would arise if they didn't pump out the pool and completely measure for the replacement liner

Getting a truly custom liner for your pool is the best way to ensure that it stands a chance of lasting as long as possible (and being a conscientious owner who stays on top of their water and chems)

They will also be able to asses the condition of the pool floor and walls, giving you a little 'heads up' on additional expenses.

While I'm never shy to point out when another PB is doing something wrong, I honestly think that your 'dudes' are doing things correctly and have earned their "A+" rating

I'd love to hear how it all works out for you and I hope you'll feel free to ask of me any questions you have concerning what or how they do things
