    Fiberglass owners... does your pool have any gelcoat cracks?

    Our in-progress fiberglass pool was not set level and as a result has so many gelcoat cracks that I can't even count them all (I've tried). Here's the thread with all the gory details:

    new-fiberglass-pool-is-full-of-cracks-help-t43101.html

    We are in the process of sending a formal letter to the builder demanding that he replace the shell (and install it properly this time). Given his behavior thus far, I wouldn't be surprised if he continues to refuse. But if we go to court and he loses, the judgement will likely be significantly higher than it would cost him to simply fix his work now, so you never know... he might have a moment of business clarity and come to the realization that not only is it the right thing to do ethically, but also financially.

    Anyway, one thing he's said several times is that all fiberglass pools have gelcoat cracks. Not necessarily to the extent that ours is, of course, but the context of this comment has been "...so when the new shell goes in and ends up having a few cracks too, you're going to demand that it be replaced again." The manufacturer's warranty literature mentions the likelihood of cracks as well, by saying "...it is impossible to prevent the gelcoat from developing hairline cracks... gelcoat is prone to develop hairline cracks as the earth shifts and settles or while the concrete expands and contracts."

    So, I suspect that if he does agree to replace the shell, he's going to want some kind of agreement that we'll accept the replacement shell even if it has a few cracks.

    I don't find that entirely unreasonable, particularly if the shell is installed carefully and level this time and "a few cracks" is clearly defined. But I have no frame of reference to know for sure. Are gelcoat cracks really common, to the point where it's unrealistic to expect a shell that is completely free of cracks? If your pool has gelcoat cracks, approximately how many and when did they occur (at the time of installation, or months/years later)?

    Take a look at this thread that is still active on TFP. He is currently doing battle with the pool builder who installed the pool incorrectly and caused cracks in the gelcoat.

    Ours doesn't have cracks but we did find a spot in the shallow end that looks as something spilled on it and left a ring stain about the 12"x12" in size. They are suppose to come out an look at it. I'll let you know what they say.

    This is our 4th year, no cracks that I can see. And since I follow the plan here, I can see a lot of my pool. :0)

    I had my Viking FG pool installed last summer...no cracks to report. And I just got out of the pool after scanning every inch with a mask

    Interesting... no one seems to have any cracks. My builder and manufacturer have made it sound like it would be unusual NOT to have any cracks.

    As you are figuring out from your experience in the other thread, it is all about the installer. Think of it like this: a great installer can install a poor shell and still make it look great while a lousy installer can install the best shell and have it go very wrong.

    I lucked out in that my installer has done over 500 fiberglass pools (and gave me contact info for each and every one of them) and does not use subs.

    None of what is happening is your fault, but you are quite the cautionary tale for others.

    I have the same pool, most likely from the same installer.
