Warranty period: 1 year

All siding expands and contracts in response to changes in humidity and temperature. Slight waves are visible in siding under moist weather conditions; shrinkage and separations will be more noticeable under dry conditions. These behaviors cannot be entirely eliminated.

Color Fade – Gradual fading or change in color, which is caused by sunlight, occurs in nearly all siding materials and cannot be prevented.

Raised Grain on Siding or Trim – Because of the effects of weather on natural wood, you should expect raised grain to develop, especially on exterior cedar trim. This is normal and not a defect in the wood or paint.

Homeowner Operation and Maintenance

Caulking – All siding and trim elements should be checked in the spring and in the fall for signs of missing, worn or failing caulk.  Re-caulk as needed.  Caulking supplies are available at hardware stores and home centers.

Cedar Acid Bleed Through – Cedar wood is prone to showing signs of acid stains, called cedar acid bleed through.  These oils and resins from the wood that come through the stain are normal. Your paint store can provide products and information to manage cedar bleed through prior to repainting.

Fiber-Cement Products – Fiber-cement based siding will require repainting and caulking just as wood products do.

Vinyl Siding – Siding will expand and contract during climate changes.  The accepted tolerance level for expansion/contraction is ½” in a 12’ distance.

  • Vinyl siding will occasionally require cleaning. Start at the top to avoid streaking and use a cleaning product recommended by your siding manufacturer. Follow directions carefully.
  • Thermal distortion – Vinyl siding can melt or distort at temperatures of 160 to 165 degrees.  Light reflecting off glass or other objects (35 feet away or more) can magnify as it reaches the siding and raising the temperature of vinyl up to the melting point; even in winter.  This is a condition for which the builder, siding and window manufactures are not responsible.  Custom screens or awnings can be added to affecting windows.  Sometimes strategically located landscape plantings can prevent reoccurrence.

Wood and Wood Products – Wood siding will require routine refinishing. The timing will vary with climatic conditions. Maintain caulking to minimize moisture entry into the siding and trim areas. Note that some paint colors will require more maintenance than others and some sides of the home may show signs of wear sooner based on their exposure to the elements. Some wood siding, such as cedar, is subject to more cracking and will require more maintenance attention.
