Stair Tread Warranty

THWOOD warrants to the purchaser that the unfinished hardwood products (stair treads, moulding and accessories) in their manufactured condition, will be free from defects in material and workmanship for one year,  including milling, assembly, dimension and grading.  THWOOD additionally warrants that our treads will not warp, cup or buckle when properly installed and maintained according to industry standard instruction procedures.

Installer / Owner Responsibility:

Hardwood is a product of nature and therefore, not perfect in any forrm or factor. Our wood products are manufactured in accordance with accepted industry standards, which permit grading deficiencies not to exceed 5%. These grading deficiencies may be of a manufacturing or natural type. Stair treads are a solid hardwood product, the relative humidity in your home must be kept between 35% to 55%.

The installer assumes all responsibility for final inspection as to grade, manufacture, and factory finish. Carefully examine hardwood products for color, grain and quality before installing it, this inspection must be done before installation.  If a product is questionable or doubtful – DO NOT INSTALL, CUT, OR OTHERWISE MODIFY THE PRODUCT.  DO NOT LEAVE STAIRS TREADS STANDING UP OR LEANING AGAINST A WALL FOR ACCLIMATION,  ACCLIMATION LIKE HARDWOOD IS 72 HOURS

Prior to installation of any hardwood product, the installer must determine that the job-site environment and the sub-surfaces involved meet or exceed all applicable standards. Recommendations of the construction and materials industries as well as local codes must be followed. These instructions recommend that the construction and sub-floor be dry, stiff, flat, and structurally sound.  THWOOD declines any responsibility for job failure resulting from or associated with sub-surface, sub-flooring, or job-site environmental deficiencies.This warranty does not cover damage or unsatisfactory performance caused by excessive moisture including, but not limited to, improper humidity inside the home, excessive ground moisture that migrates into the home for any reason, water leaks caused by broken pipes or appliances, weather conditions or natural disasters such as flooding or excessive rainfall.
Installation is not a manufacturing defect of THWOOD and is not covered under this warranty. Any installation issues should be referred to the installer who installed the hardwood products from.  Use of stain, filler, or putty stick for touch-up during installation should be accepted as normal procedure. This warranty does not cover damage or unsatisfactory performance caused by excessive moisture including, but not limited to, improper humidity inside the home, excessive ground moisture that migrates into the home for any reason, water leaks caused by broken pipes or appliances, weather conditions or natural disasters such as flooding or excessive rainfall.

Stair Tread Adhesive

We recommend only Urethane based Adhesives for Solid hardwood products (stair treads and unfinished flooring).

. If you use these ultra low VOC adhesives, you will almost certainly have warping and cupping issues causing you to have to replace your installation. This type of complaint is typically not covered by the adhesive manufacturer’s nor our warranty.  Because Liquid Nails’ products are labeled very similarly and packaging can vary between location and retailer, we strongly discourage the use of any water based brand of adhesive, including Liquid Nails, for your stair installation. Most of these adhesives have a greater amount of moisture than what is suited for solid wood and is known to
cause cupping of solid wood treads at the project job-site.
