We're looking to attack our leaky fiberglass walled IG this spring or summer. Have sort of eliminated the obvious already (pump/filter/heater, did some food color testing) without finding out much, so I guess it's time to find a pro. At least we've got plenty of nice rain water in the pool! - see news stories about floods in Gurnee, schools closed because of flooding, etc. Based on some fooling around last year, I think the water level comes to an equilibrium around the bottom of the skimmers so we'll see about that this week.
We're near Gurnee (far northern suburbs of Chicago). Any recommendations or warnings on who we might try?
Thanks for any info.
