What does the Preserve® (ACQ) warranty cover?
The warranty covers termite infestation or fungal decay only. The ACQ preservative does not work on insects that do not ingest the wood (e.g., borer beetles, carpenter ants, carpenter bees, etc.). Termites recognize the wood as inedible and move on. Wood has a natural tendency to warp, twist, split, etc. We cannot guarantee that this will not happen, therefore, it is not covered in our warranty. Does Preserve® treated wood last as long a traditional CCA treated wood? Yes. Preserve® treated wood has the same long lasting performance in providing protection against decay and termite attack that people have come to expect from traditional CCA treated products.
