INSTALLER / OWNER RESPONSIBILITY—VERY IMPORTANT
INSTALLATION CONSTITUTES ACCEPTANCE of flooring material,
subfloor/substrate, the jobsite itself including the ambient temperature and relative
humidity at the time of installation, moisture content of the subflooring and flooring,
and all impacting variables that may affect a wood floor. It is the responsibility of both
the installer and owner to inspect and approve each piece of flooring prior to
installation. IF THE FLOORING AS SUPPLIED WILL NOT SATISFY THE
CUSTOMER IN FULL, DO NOT PROCEED TO INSTALL. The decision not to
proceed must be made within the first 10% or 100 square feet of flooring opened,
whichever is less. Industry standards allow a variance from grading and manufacturing
tolerances of 5%.
Note to Installers: Protect your business. Your hard work testing moisture conditions is
lost if you can’t prove it on request. It is now recommended you photograph moisture
readings from two meters, including noting the location, date, and initials on the
subfloor in permanent marker. This is a permanent record of your work that can protect
you if you are ever challenged to prove you did your job completely and correctly.
Many important decisions must be made at the installation site, and therefore must be
the sole responsibility of the installer/owner. These include but are not limited to proper
storage and handling, complete evaluation of site conditions including moisture testing
of the subfloor and flooring, acclimation of flooring to appropriate conditions, subfloor
preparation, flooring layout, milling, grade, color and gloss, scraping, proper
installation methods, sufficient quantity on hand to complete the job, and jobsite
cleanup. For best results, we suggest using a National Wood Flooring Association
Certified Professional to install your floor. A list of active NWFA Certified Professionals
in your area can be found online at www.nwfacp.org
Site Conditions, Handling, and Storage (NWFA Installation Guidelines, Sec. I):
Solid hardwood flooring may be installed above or on grade, not below grade.
Hardwood flooring should be installed after all other construction that may affect them
is completed. Concrete, drywall, plumbing and any other “wet work” should be
thoroughly cured. Factory finished flooring is finished woodwork, handle carefully to
avoid damage.
