20-Year Limited Warranty, Prorated and Transferable Once

What and Who is Covered:

CertainTeed warrants to the property owner that its STONEfaçade Cladding System is free from manufacturing defects in material and workmanship if installed according to our applicable installation instructions, subject to the terms and conditions of this Warranty. If CertainTeed determines, in its sole discretion, that its STONEfaçade has a manufacturing defect under the terms of this Warranty, CertainTeed will, at its option, either (1) contribute toward replacement STONEfaçade or (2) refund the amount paid by the original property owner for the STONEfaçade. No labor costs or other costs associated with installation, removal or replacement are included in either option above. If a claim is made to CertainTeed during the first two (2) years after original installation and CertainTeed determines that a manufacturing defect exists, under the two options listed above for the product proven to be defective, CertainTeed will provide either replacement STONEfaçade or a refund. After two (2) years, the amount available under this Warranty for replacement STONEfaçade or for a refund will be based on the Proration Calculation listed below.

Should the property owner not have the original invoice for the STONEfaçade, CertainTeed will determine the original cost based on the reasonable cost of the STONEfaçade at the time of original installation.

Proration Calculation:

CertainTeed’s maximum contribution toward replacement STONEfaçade or a refund under this Warranty will be calculated by using the cost of the STONEfaçade determined by CertainTeed to be defective reduced by 1/216 for the number of months from the start of the prorated Warranty period (year 3) to the date when CertainTeed determines that the STONEfaçade has a defect. For example, given that the Warranty is for 20 years (240 months) and should you make a valid claim in the last month of the 15th year of the Warranty (i.e., the 180th month minus(-) the first 24 months = 156), CertainTeed will not cover labor but will pay you, at CertainTeed’s sole discretion, either (1) the reasonable cost of replacement STONEfaçade reduced by 156/216 of the cost or (2) a refund of the original cost of the STONEfaçade reduced by 156/216 of the original cost. This Warranty provides coverage for 20 years starting from the original date of installation.


This Warranty may be transferred once from the original property owner to the first subsequent owner

CertainTeed reserves the right to discontinue or modify any of its siding products, including the color, and shall not be liable as a result of such discontinuance or modification, nor shall CertainTeed be liable in the event the replacement material varies in color or gloss in comparison to the original product as a result of normal weathering. If CertainTeed replaces any material under this Warranty, it may substitute products designated by CertainTeed to be of comparable quality or price range in the even the vinyl siding product initially installed has been discontinued or modified.

If you believe your STONEfaçade has a manufacturing defect, you must promptly notify CertainTeed in writing and provide proof of property ownership, the date you bought the property, and the date of your STONEfaçade products purchase and installation. In order to properly evaluate and process a Warranty claim, CertainTeed may require you to submit a product sample to CertainTeed for analysis and/or permit a CertainTeed representative to inspect the installed product, if required.
