Limited Lifetime Warranty

Brothers Global Inc d.b.a. US Cabinet Depot warrants to the original consumer purchaser that cabinetry, door hinges and drawer glides will be free from detects in material and workmanship under normal use and service for the lifetime of the product (Proof of Purchase is required). This warranty is not transferable and only applicable to product used for residential purposes. Representatives of Cornerstone Cabinet Company do not have the authority to change or enlarge this warranty.

This warranty does not cover normal wear and tear, damage or defects caused by accidents, misuse, abuse, or lack of necessary maintenance; nor does it cover alteration, modification, improper installation, improper handling / storage, environmental conditions, nor any labor expenses.

Brothers Global Inc. d.b.a. US Cabinet Depot, at our option, may elect to repair or replace with a functionally equivalent product product covered by this warranty. Some replacement parts are subject to availability and may differ from original parts received. Return of defective product may be required for a replacement to be issued. Repair parts or replacement parts are at the expense of Brothers Global Inc., but customer shall bear all other expenses. These expenses may include, but are not limited to, cost of removal and re-installation of product, labor expenses, etc.

Just as no two trees are alike, no two pieces of wood are alike. The variation in color and grain pattern in wood adds to its natural beauty and is not considered an imperfection. Environmental factors, including but not limited to artificial / natural light, moisture, cleaners, smoke, etc, may cause the darkening or mellowing of a cabinet over time. This is a natural process and can be expected. This warranty does not cover the natural aging or darkening / mellowing of wood color, the inherent growth characteristics of or variation in wood.

Some of the cabinet lines feature a glazed finish which accentuates the door and drawer front profiles. This glaze is hand applied over a stain or paint and may, due to the nature of application, consist of random drips, runs, etc. As glazing is a hand applied process there will be variations in color and appearance from door to door and cabinet to cabinet. This is not considered a defect and is considered normal with hand applied finishes. It is the nature of wood to expand and contract to varying degrees depending on climate conditions. As a result, cabinet lines with painted surfaces may show fractures in the paint at joints. This is normal and is not considered a defect.

This warranty is valid only in the United States of America and Canada and is not transferable. All implied warranties are limited in duration to the shorter of the period provided by law or the period of this warranty. To the extent permitted by law, this warranty excludes special, incidental, or consequential damages. Some states do not allow the exclusion or limitations of incidental or consequential damages or limitations on how long an implied warranty lasts, so the above limitations or exclusions may not apply to you. This warranty gives you specific legal rights; you may have other rights which vary from state to state. To exercise this warranty, please contact the Cornerstone Cabinet Company from whom you purchased the product. Report, in writing, to Orders@CornerstoneCabCo.com all defects claimed and include proof of purchase documentation.

Please note that cabinet styles and finishes can get discontinued by the manufacturer which is beyond the control of Cornerstone Cabinet Company. If the cabinets you purchased are no longer available or discontinued by the manufacturer, or if we no longer sell that particular finish/manufacturer any longer, we will do everything we can, however, we may not be able to get parts or replacements. If we no longer sell that manufacturer but are still able to obtain parts, you would only be charged the cost of the parts plus shipping. If we`re no longer able to get parts from the manufacturer but are able to locate the parts needed through another source, you would only be charged the cost of the parts plus shipping.

Cornerstone Cabinet Company reserves the right to determine the most cost effective and efficient method to correct defective merchandise that does not involve total replacement. Example: replace a door - not the entire cabinet. Cornerstone Cabinet Company and its manufacturers determine what is “defective” - not the customer. Pictures will be required in order to receive replacement parts.

Climate Considerations

Dry wood undergoes small changes in dimension with normal changes in relative humidity. More humid air will cause slight swelling and drier air will cause slight shrinkage. If you install our product in an extremely humid area or in a building without air-conditioning you can expect the cabinet components to change dimensionally. This change is usually more in width than height. The cabinets are designed to accommodate some of this dimensional change and most cabinets feature hinges with significant adjustability. Please note that if you leave your cabinets in direct sunlight that overtime the color can fade, this is not a manufactures defect and thus would not be covered under our warranty.

Warped Doors

There are three reasons why cabinet doors may warp or appear warped.

  • Doors may warp a small amount soon after installation because cabinets are taken from a controlled factory environment and placed in a different environment. Warped doors will generally straighten out after a new home goes through a complete heating and cooling season. The manufacturer requires that doors go through a complete heating and cooling season before replacements are considered. NOTE: A hinge adjustment will improve the fit of the door as the cabinet progresses through a heating and cooling season.
  • Improperly installed cabinets can cause doors to appear warped. The manufacturer requires that doors be tested for warp before replacements are considered. See step four.
  • Improperly adjusted hinges can cause doors to appear warped. A hinge adjustment will improve the fit of the door. The manufacturer requires the doors be tested for warp before replacements are considered. See step four.
  • The best time to test a door is after a complete heating and cooling season. To test a door, lay the door on a flat surface and measure, to the nearest sixteenth of an inch, the gap between the surface and the door.

Door Height

Warped is indicated when:
12″ or less - gap is greater than 1/16″
13″ to 24″ - gap is greater than 1/8″
25″ to 41″ - gap is greater than 3/16″


Wood & Finish Characteristics

Graining differences, as well as normal color change can be expected. Different wood species in all finishes exhibit color change when exposed to different types of light. Plywood, veneer and MDF panels and accessories will stain differently than hardwoods and will vary in color, graining, sheen and tone depths. All wood species will exhibit other characteristics, including: knots, pinholes, sap runs and darkening with age. Here are the characteristics specific to individual wood species and finishes:
    • Birch

      Birch is a medium-density hardwood with a distinct, moderate grain pattern that ranges from straight to curly or wavy. The predominant sapwood color is white to creamy yellow, while the heartwood varies in color from medium or dark brown to reddish brown. The natural characteristics described below are normal and should not be considered defects:

      • Creamy yellow to reddish brown tones
      • Mineral streaks that are a natural characteristic and will appear darker with stain
      • Wavy, curly bird`s eye or burl graining resulting in color variation within the same door

Painted Finishes

Painted woods offer a classic look for your cabinetry. Paint will develop hairline cracks in the finish, most notable around the joints - especially miter joints. This is a result of natural expansion and contraction of the wood. With that, MDF center panels are commonly used with painted door styles to help with the stability of the door. Painted doors require more maintenance for chips, marks, residue from normal kitchen use, and hand/finger prints. Paint may have a slight difference in tones between doors, drawer fronts, face frames and mouldings.

Glazed Finishes

Glazing is most apparent in contours where “hang-up” would occur (areas where the Glaze `gathers` and is more visible). Glaze adds depth, dimension and an understated sheen. Glazing results in each piece being unique and individualized. When choosing glazing, please understand that each cabinetry component will have a finish appearance that is slightly different from the next. Glazing over lighter stains will result in more noticeable variation than over darker base stain colors. Painted doors that are glazed also commonly use MDF in lieu of solid wood for center panels to add stability against seasonal thermal dimensional changes. Glazing marks may appear outside of the general `hang up` area. Additional maintenance may be required for glazed doors against chips, marks, hand/finger prints, and residue from normal kitchen use.
