If you would like to contact me, I'd be glad to help you contact a certified Duro-Last contractor in your area and possibly even the contractor that orginally installed the material.
As one of the other posts mentioned, we don't want anything to be done with the Duro-Last material that may alter the warranty. Thus it is best to deal with a certified installer.
Feel free to reply to this thread, email me at firstname.lastname@example.org
or call 800-248-0280 x1080. Thanks.
