Sun Mountain doors are warranted to be of sound material and workmanship and to be free of defects that cause the door to be unfit for ordinary recommended use for the period of twelve (12) months from the date of shipment. In addition, interior doors that have been pre-finished by Sun Mountain are warranted for an additional four (4) years. This extended warranty applies only to the construction of the door, and not the factory pre-finish itself. See Sun Mountain’s “Door Finishing and Care Instructions” for details on finish maintenance.

If a defect occurs within one year from the date of shipment, written notice of the defect must be provided to Sun Mountain. Buyer shall not return any goods until Sun Mountain has been provided a reasonable opportunity to inspect the goods at Buyer’s premises to determine whether a defect exists. Sun Mountain will not be liable for any doors repaired, returned, or replaced without prior written consent. If warranted doors contain defects covered under this limited warranty, Sun Mountain shall be limited to, at Sun Mountain’s option, 1) repairing or replacing the doors or 2) refunding the purchase price of the doors to Buyer. Doors will be repaired or replaced in the same stage of fitting and/or finishing as they were originally supplied. Sun Mountain will not pay any cost to remove defective doors or to install new doors, and will not be responsible for any finishing costs or consequential damages. Final warranty inspection will be made at Sun Mountain’s location, upon receipt of defective product. If the claim is found by Sun Mountain, in its sole discretion, to be invalid, neither repair/replacement nor refund will be issued.

This limited warranty does NOT apply to any of the following:

  • Doors and other products (such as sidelites and transoms) more than 8′ tall or 3′6″ wide (Note: For double doors 8′ tall and for all doors greater than 8′ tall or 3′6″ wide, Sun Mountain strongly suggests multi-point locking hardware to protect against warp)
  • Doors that have warp that does NOT exceed 1/4″ in the plane of the door (see below)
  • Doors less than 1-3/4″ thick for exterior use
  • Doors that have not been properly sealed on all six sides within 14 days of delivery, including the top and bottom edges of the door
  • Damage caused by failure to comply with Sun Mountain’s “Door Finishing and Care Instructions”
  • Damage due to improper or incorrect installation
  • Exterior doors used in a commercial application
  • Damage caused by others or by any cause beyond the control of Sun Mountain including, but not limited to, damage caused by misuse, abuse, accident, mishandling or by fire, flood, earthquake, storm, tornado or other acts of nature
  • Misuse of a door including, but not limited to, using a door in an exterior application without adequate overhang (Note: Adequate overhang depends on the typical weather conditions of the site where the building is located, but generally means an overhang projecting a distance away from the door at least equal to one-half the elevation difference between the bottom of the door and the base of the overhang structure, measured at the highest point of the overhang structure, and at least 6′ wider than the door unit, including sidelites and transoms; at least 3′ overhang on each side).
  • Doors and other products with black finishes on exterior surfaces (Note: To reduce the chance of warping or checking, Sun Mountain strongly discourages dark-colored finishes on exterior surfaces, especially if the door is exposed to direct sunlight)
  • Doors and other products with clear coat finishes on exterior surfaces
  • Discoloration or rusting of decorative metal accents (clavos, grilles, strap hinges, etc.)
  • Damage due to trimming the door more than 1/2″ from the top or 1-1/2″ from the bottom of the slab
  • Panel movement or shrinkage (Note: Panels in Sun Mountain doors are designed to “float,” and will expand or contract in response to environmental conditions)
  • Expansion or contraction due to varying environmental conditions, such as temperature and humidity
  • Gates, or doors used in gate applications
  • The appearance of any field-finished door

For the purposes of this warranty, warp is defined as any distortion in the door itself and does not refer to the relationship of the door to the frame or jamb in which it is hung. The term “warp” includes bow, cup, and twist. In measuring the amount of warp in a door, the following method shall be used: Bow, cup, and twist shall be measured by placing a 7′ straightedge on the suspected concave face of the door at any angle with the door in its installed position. The measurement of warp shall be made at the point of maximum distance between the bottom of the straightedge and the face of the door.

If the claimed defect is warp, Sun Mountain may defer replacing or refunding the door for a period of up to twelve (12) months from the date of claim or date of installation, in order to permit conditioning and equalizing to humidity and temperature conditions. The deferral period will not be counted against the one-year warranty period.

In addition, the following natural properties and characteristics add to the beauty of wood doors and are not considered defects:

  • On all knotty-grade wood species, knots that show light or underlying substrate through the door will be filled, and knots that do not show light or substrate through the door and are not filled should be expected and are not considered defects (Note: On knotty wood species, the location, quantity, and size of knots is unpredictable and uncontrollable)
  • On all knotty-grade wood species, cracks in the surface of the wood are a natural characteristic and are not considered defects, unless light or underlying substrate shows through the crack
  • On all select-grade wood species, knots less than the size of a quarter are acceptable and are not considered defects
  • On all wood species, natural variations in the color, texture, and density of the wood are common and such variations are not considered defects
  • On wire brushed doors, an inconsistent face plane where stiles or mullions meet rails is acceptable to a depth change of 1/16″, and an apparent open connection between stiles and rails is acceptable to a width of 1/32″
  • Surface checks of up to 1/32″ in width are not considered defects (Note: Such surface checks do not compromise the structural integrity of the door)

For doors with glass, glass units/lites are warranted according to the glass manufacturer’s warranty. The following items related to glass units/lites are not considered defects:

  • Defects or scratches in the glass as a result of handling or installation
  • Defects as a result of product modifications or glass shading devices (e.g., glass tinting, security systems, improper painting or staining, insulated coverings, etc.)
  • Water infiltration of the glass, other than as a result of a defect in manufacturing, materials, or workmanship
  • Condensation in the glass
  • Slight glass curvature, minor scratches, or other imperfections in the glass that do not impair structural integrity or significantly obscure normal vision
  • Broken glass, other than as a result of manufacturing or shipping damage

Note: This warranty is effective for all products manufactured or sold after April 1, 2023.
