Conestoga's Warranty

Conestoga's Warranty Information

Conestoga Wood Specialties Corporation warrants that, for a period of one year from the date of shipment, their products will be reasonably free of defects in material and workmanship. When properly handled their products will conform, within acceptable tolerances, to applicable manufacturing specifications. This limited warranty applies only to Conestoga products which are stored, handled and installed properly. Conestoga will not be responsible, or liable for any indirect, consequential or incidental damages or costs sustained by the user.

Conestoga's warranty is limited solely to the value of the original materials purchased from Conestoga and is further limited in the amount to the purchase price paid for such materials. Conestoga will not be liable for the cost of extraneous materials, labor, travel cost, installation expenses, or other related expenditures.

Conestoga will not be liable for damages to products caused by improper handling, storage, assembling, finishing or installation by the customer. Our products are not warranted against expansion occurring as a result of high moisture or humidity conditions.


Natural characteristics in the wood (burls, grain patterns, pin knots, mineral deposits, sap, etc.) that fall within Conestoga's specifications will not be considered defects.

Most wood species, particularly Cherry, will darken naturally with age. Conestoga is not liable for the change in appearance of any product, finish, or unfinished, due to this aging process. Results of aging will be more obvious when using clear, light or glazed finishes.

Expansion / Shrinkage

Mitered doors allow a .010" joint gap, at the inside bead/corner.

Mitered doors are not warranted against joint separations that occur as a result of high humidity or moisture conditions. Painted or opaque finishes are not recommended on mitered designs.

Because the individual staves of the panel continue to contract and expand, lines many appear on solid wood panels and offsets may develop from one stave to another. These will not be considered defective. To eliminate the chance of stave offsets, Conesotga recommends utilizing an MDF panel option, when using painted finishes.

Vertical grain panels that exceed 22" wide by 44" high in either single or multi-panel
products are not warranted against expansion, warpage, cracking or open framing joints.
Allowable tolerances of bow, warp or twist for a single panel, multi-panel, frame only, and Mullion doors are as followed:

  • Single panel up to 26" wide and 48" high = 1/8"
  • Multi-panel up to 26" wide and 48-1/16" to 64-15/16" high = 1/4"
  • Multi-panel up to 26" wide and 65" to 83-15/16" = 5/16"
  • Single panel, single opening frame-only, and mullion doors over 26" wide and 48" high, will not be warranted (mullion lite not to be included in opening count).
  • Any door exceeding 26" wide or 83-15/16" high, will not be warranted.

Allowable tolerances for contraction, expansion, bowing, warping and twisting for one-piece products are as followed:

  • Up to 12" wide and 21-15/16 high = 1/8"
  • 12-1/16 to 22" wide or 22" to 43-15/16" high = 1/4"
  • Any one-piece product exceeding 22" wide or 43-15/16" high will not be warranted.

Allowable tolerances for contraction, expansion, bowing, warping and twisting for three-piece products are as followed:

  • Up to 44" wide and 14" high
  • Any three-piece solid product exceeding 44" wide or 14" high will not be warranted.

Conestoga expressly disclaims any and all other warranties, whether expressed or implied, including all warranties of merchantability and warranties of fitness for a particular purpose with respect to its products.

Finishing / Color

Conestoga's finished products carry a one year warranty against peeling, blistering fading, or cracking, but no warranty against discoloration. Conestoga assumes no responsibility for damages or poor color match when finish is applied by the customer.

Veneered panel doors are not guaranteed to match solid wood framing on the same door in either the raw or finished state. Veneers will absorb stain differently than solid wood. The mismatch of solid and veneers is not considered defective.

Solid wood moulding color may differ from doors of the same species.

Most wood species, will darken naturally with age. Conestoga will not be held liable for the change in appearance of any product, finish, or unfinished, due to this aging process.

Conestoga recommends that a finished sample door be ordered prior to ordering any finished job. We do not suggest ordering a large or complex finished product based on small sample swatches.

Conestoga has established an acceptable range of color, for finished products. Orders placed over an extended period of time may vary in color due to natural aging of the finished substrate and slight variations from batch to batch in finish materials. These variations will not be considered defective and will not be warranted by Conestoga.

Conestoga's finish materials are interior grade only and not intended for exterior use. Exposure to outdoor conditions will cause failure and will not be warranted.

Due to the many variables involved in any finish process, Conestoga assumes no responsibility if products stain be the customer using the DuraGuard system do not produce an exact match to refinished products purchased from Conestoga.

Painted or opaque finishes are not recommended on Mitered designs. To reduce the chance of joint separation, paint cracks, etc., Conestoga highly recommends using a MT (mortise & tenon) constructed MDF door design, or at the very least a Hybrid door (Solid wood framing with a MDF center panel).

Veneers will absorb stains and top coats differently than solid wood. This mismatch of solid wood and veneer is not considered defective.

Conestoga's off assembly line spray/finishing booths are down draft booths that draws the air to the floor, but the majority of our products are done on our flat assembly line systems. Both are controlled air flow environments. With that being said, minor amounts of debris in the finish would still be considered in spec. This is especially true on glazed product. Minor flaws such as dust particles, dimples and lint are more apparent with opaque finishes than with wiping stains. The presence of small amounts of these minor occurrences will be considered acceptable.
