Sealing may seem like a quick fix, but if the waterproofing is compromised, it’s only a short-term solution that could cost you much more in the long run. If there is evidence of waterproofing failure, any company offering a seal with a warranty is misleading you, and unfortunately we get a lot of calls from these homeowners. Retiling is the only way to ensure a permanent repair. When it comes to the overall resale value of your property, you can’t afford NOT to fix it right the first time.
