Finishing Doors

Because Woodgrain doors are crafted with only the finest materials, you can choose from a wide variety of stain or paints to finish your door. Paint dealers have a broad selection of color chips on hand to demonstrate the look you can achieve when finishing Woodgrain doors. Please remember that dark stains tend to magnify blemishes. If you are staining or painting your door a dark color, extra care needs to be given during the preparation process. For optimal staining consistency, a sander/ sealer is highly recommended. Do not use dark color stains or paint on doors exposed to sunlight, as some expansion and contraction of door parts may occur.

Fitting and Hanging

  • Immediately after cutting and fitting (before hanging), seal all cut surfaces and ends of door with an effective quality sealer. See exterior and interior finishing recommendation for complete instructions.
  •  Prior to exterior exposure, doors should be finished with complete finish system.
  • When hanging door, allow adequate clearance for swelling of door or frame in damp weather. Allow approximately 3⁄16” clearance for swelling when the door is installed in fully dry conditions. Jambs must be plumb.
  • Do not cut doors down in height by more than 2-9⁄16” (13⁄16” maximum from top, 1-3⁄4” from the bottom). Care should be taken in cutting doors down in width (maximum 1⁄8” each side) to avoid exposing engineered core. Use sharp fine tooth saw for trimming ends of doors.
  • Caution must be used to avoid impairing the strength of the door when fitting for locks. Allow at least 1” of wood back of mortise.
  • Use three hinges on doors up to 7’ in height and four hinges on doors over 7’. Hinges must be set in a straight line to prevent distortion.
  • Jambs and stops must be set square and plumb.
  • For best performance, any exterior door should be installed under an overhang equal to the height of the door.
  • To minimize heat loss and save energy, use weatherstripping.

Do not use metal objects, (razor blades etc.) to remove caulking compound or paint and varnish residue, it is known to scratch the tempered glass. Please do not use compressed air to blow off wood doors, as condensation in the air lines may cause irregular finishing results.

Storing and Handling

  • Do not walk on any door units. Some units contain glass.
  • Avoid leaving unfinished doors in direct sunlight. Prolonged exposure to direct sunlight will discolor the wood and bake on the plastic film which protects the glass during the finishing process.
  • Avoid dragging doors across one another.
  • Keep doors clean.
  • Store doors flat on a level surface in a dry, well ventilated interior space.
  • Doors should be conditioned to average prevailing relative humidity of the locality before hanging. This generally takes 48 to 72 hours.
  • Doors should be delivered to the building site only after the concrete, plaster, stucco, sheet rock work and paint are completely dry.
  • Doors should not be subject to abnormal heat, dryness or humidity for prolonged periods. Avoid sudden changes such as forced heat to dry out a building.
  • Doors must be finished immediately upon delivery to the job site.
  • If the doors are to be stored on the job site, the entire door including top and bottom edges must be sealed with a clear or pigmented based sealer to prevent moisture absorption. All six sides of the door must be properly sealed for warranty to apply.



Your Woodgrain door has been handcrafted to last for years to come. But, like any fine piece of furniture, its finish will require periodic maintenance to keep it looking great and provide proper protection against the elements. Regular finish maintenance is also a requirement of the warranty that is included with every Woodgrain door.

Here are some signs to watch for that may indicate it is time for maintenance:

  • Hairline cracks in the top coat of finish.
  • Changes in the color of the finish.
  • Changes in the texture of the finish, such as flaking or scaling.
  • Dullness or chalkiness in the finish.

If you live in a severe climate or your entry receives a lot of direct sunlight from a southern or western  exposure, you will want to examine your door’s finish often. Depending on these conditions, you may also need to refinish the door more frequently.

Industry Terms

Click Here for Terms



Woodgrain Doors (hereafter Seller) doors are warranted to be of sound material and workmanship and to be free of manufacturing defects which would cause the door to be unfit for ordinary recommended use for the period of twenty-four (24) months on interior doors and twelve months (12) on exterior doors from the date of shipment provided the handling, installation, and finishing proper instructions are followed. Failure to follow these guidelines voids the warranty.

Normal characteristics of kiln dried wood include but are not limited to, minor swelling and shrinking of parts made from wood, raised grain, minor pitch pockets, natural grain and color variations. Natural expansion and contraction of wood occurs with variations in climatic and atmospheric conditions such as humidity and temperature and is not a defect hereunder.

Warp in the plane of the door itself will be considered a defect only if it exceeds one-quarter inch (1/4″) when measured as a deviation from a straight edge. Doors over 3-0 wide or 7-0 high are excluded from the warranty against warp. Improper hanging of the door or unsquare door frames are not considered as defects. Louver doors wider than 3-0 wide are not covered for slat warp and bow.

Any doors used in an exterior application must be at least 1 3⁄4″ thick and must be installed under an adequate overhang. An adequate overhang depends on the typical weather conditions of the site where the building is located. This means an overhang of 50% of the height of the doorway in Northern or Eastern exposures (reference illustration where Y= Height of the Doorway and X = Length of Overhang). For doors painted or stained dark colors and/or severe exposure, extreme Southern, Southwestern and Western exposures the overhang must equal the height of the doorway (Y=X) where Y = Height of the Doorway and X = Length of Overhang.


Any doors found to be defective by the Seller will be repaired or replaced, or the purchase price will be refunded at the option of Woodgrain Doors, provided the handling, installation and finishing instructions have been followed.

An extended warranty period is granted solely for seal failure on insulated glass units (moisture between glass) for a period of ten (10) years from the date of manufacture. At Seller’s sole discretion, the replacement door or glass will be shipped FOB from the Woodgrain Doors factory. Seller will not, under any circumstances, be liable for installation, refnishing or painting. Cracked, scratched or broken glass is not covered by this warranty. The glass warranty will be void if the product is not properly installed according to Sellers installation instructions, or is used in or around swimming pools, saunas, sprinkler systems or greenhouse enclosures; or if installed over 5,000 ft. above sea level unless units were ordered with high altitude breather tubes. The warranty on doors will be void if the product is used in or around swimming pools, saunas, sprinkler systems or greenhouse enclosures. No agent, employee or representative of Seller has any authority to bind Seller to any affirmation, representation or warranty concerning Seller’s products, except as expressly stated herein.

The foregoing is in lieu of all other expressed warranties. All implied warranties of merchantability or fitness for a particular purpose are hereby limited in duration up to the two-year period stated herein. The liability of Woodgrain Doors is expressly limited to replacement or repair of the defects of the door, or refunding at its option. Woodgrain Doors will not be liable for any other expense, injury, loss or damage, whether direct or consequential, arising in connection with the sale or use of, or inability to use, any product of Woodgrain Doors, for any purpose. No purchaser shall be entitled to consequential damages as de ned in the Uniform Commercial Code. Final determination of whether or not a defect exists shall be made solely by Seller in accordance with procedures established by Seller.
