Warranty

One of the many benefits of choosing Viwinco is our industry leading warranty program. We want to support our products long after they are installed in your home. Because of this, we have developed a comprehensive limited lifetime warranty program that covers each of our products for various things. Click through the tabs below to learn more about our warranty, or view the tables below for a high-level overview.

Lifetime Limited Window and Patio Door Warranty

Viwinco Limited Lifetime Warranty

Viwinco, Inc. (“The Company”) warrants its vinyl window and patio door products to be free from manufacturing defects for the lifetime of the original purchaser, as long as he/she resides in the single-family residence in which the products were installed. In the event that the home where the windows were installed is sold, that lifetime warranty becomes a 20-year warranty and is transferable to one subsequent owner with the remainder of the 20 years from the manufacture date being covered. A transfer fee of $50.00, accompanied by the document entitled “Certificate of Transfer of Warranty to 2nd Property Owner,” must be received by us in order for the warranty to be transferable.

If the purchaser resides in a non-residential or commercial property, the windows will be covered under warranty for 20 years.

Vinyl: Lifetime Coverage

Lifetime coverage against manufacturing defects such as peeling, flaking or blistering is included.

Insulated Glass Unit: Lifetime Coverage

For as long as the purchaser owns and resides in the residence in which the windows were installed, the sealed insulated glass unit is warranted against defects resulting in material obstruction of vision from film formation (caused by dust or moisture in the dead airspace of the sealed unit). Should the glass fail, Viwinco, Inc., will provide the purchaser with a replacement sealed glass unit at no charge. In the event that this lifetime warranty is transferred, it will become a 20-year warranty, covering the remainder of the 20 years from the date of manufacture.

If the purchaser resides in a non-residential or commercial property, the insulated glass unit will be covered under warranty for 20 years.

NOTE: Slight imperfections or wavy distortions in the glass that do not impair structural integrity (e.g. related to laminate interlayer or heat-strengthening of glass) are not considered defects. ALL GLASS WARRANTIES ARE VOID IF ANY FILM IS APPLIED TO GLASS.

Screens: One-Year Coverage

One-year coverage against manufacturing defects to screens and screen material is provided. Please see “Limitations and Conditions” for restrictions.

One-Year Full-Coverage Labor Warranty for Vinyl Windows

Viwinco, Inc. will repair or replace (including the cost of removal of the defective product and/or installation of replacement product) at The Company’s sole option but at no cost to the original purchaser. Any Viwinco, Inc. vinyl window proven to be defective during a 1-year period from date of installation. Viwinco’s maximum liability under the full-coverage labor warranty will be equal to the reasonable cost to repair or replace the defective product at the then-current cost, including labor, in connection with the repair or removal of the original product and/or installation of the replacement product.

Hardware: Lifetime Coverage

Lifetime coverage against manufacturing defects to the hardware is provided. What is not covered by this hardware warranty is normal wear due to weathering (sunlight, atmospheric conditions, severe weather incidents). Normal wear and tear that results in discoloration, pitting, or similar outcomes due to exposure in highly corrosive environments is also not covered.

Casement and awning hardware should be maintained by cleaning with a mild detergent on a regular basis, drying fully, and lubricating to ensure smooth operation.

In the event that this lifetime warranty is transferred, it will become a 20-year warranty, covering the remainder of the 20 years from the date of manufacture.

If the purchaser resides in a non-residential or commercial property, the hardware will be covered under warranty for 20 years.

Limitations and Conditions

Viwinco, Inc. shall have no liability whatsoever under this warranty for:

  1. Any damage or failure caused by improper handling or storage, or by installation not in strict adherence with Viwinco’s written instructions.
  2. Any damage to the product caused by the following: impact of foreign objects (except as provided under our Cambridge Lifetime Glass Breakage Warranty); extremes of weather or other acts of God; fire, explosion or other casualty; insects or other vermin.
  3. Windows that have been painted, varnished or similarly coated over the original vinyl surface.
  4. Damage caused by failure to protect wood surfaces against moisture.
  5. Defects or damage caused by normal weathering, including but not limited to the effects of air pollution, exposure to harmful chemicals, and exposure to the elements.
  6. Defects in insect screens that occur more than twelve months from the date of window manufacture.
  7. Corrosion of any metal parts, including screws (otherwise known as hardware), when installed within two miles of the coast.

Condensation

Condensation or mildew on windows may occur as the natural result of humidity within the house or building caused by interior/exterior temperature differentials and does not indicate a manufacturing defect. It is even possible for frost to appear on a window as a result of excessive condensation in cold weather. Window condensation cannot be prevented if the humidity level in your home is too high. CONDENSATION IS NOT THE RESULT OF A DEFECTIVE OR FAULTY INSTALLATION; IT IS THE RESULT OF EXCESS HUMIDITY. Thus, the damage caused by condensation is not covered by this warranty.

Cambridge Lifetime Glass Breakage Coverage

If glass is broken for any reason after the window has been installed, Viwinco will provide a replacement sealed glass unit at no charge for the lifetime of the original purchaser. This glass breakage warranty applies only to Viwinco Cambridge double-hung and single-hung windows. If Cambridge windows are used in a new construction application, the warranty will take effect with the occupancy of the home. This warranty does not apply to commercial applications.

The sole remedy under this glass breakage warranty is limited to replacement of broken glass, or refund of the broken glass purchase price, at Viwinco’s sole option (See REPAIR PROCEDURE).

Viwinco Color Warranty

Twenty-year coverage against manufacturing defects such as cracking, flaking, blistering, or peeling of the factory-applied exterior laminate film. The factory-applied laminates are also warranted against any significant color change for 20 years from the date of manufacture. Fading, discoloration or color change of the laminate will not be considered a defect unless it exceeds 3.4 E units (+/-) within the first 10 years of manufacture, or 6.8 E units (+/-) within the first 20 years, as calculated in accordance with ASTM D2244, paragraph 6.2.

In the event that this 20-year warranty is transferred, it will remain in effect for the remainder of the 20 years from the date of manufacture. If the purchaser resides in a non-residential or commercial property, the product will be covered under warranty for 20 years.

If the product is found defective, the Repair Procedure outlined in this warranty will be followed.

Note: Viwinco, Inc. will not be held liable for any charges associated with labor or installation beyond one year from the date of manufacture. This Limited Warrranty does NOT cover damage incurred by or attributable the following:

  • Caustic or industrial chemicals or solvents, such as but not limited to acetone and ethyl acetate, fuming sulphuric acid, amines, and abrasive products
  • Normal effects of weathering, such as non-uniform fading or color change caused by unequal exposure of surfaces to the sun and elements
  • Damage resulting from incorrect product installation or flaws in building design or construction
  • Damage caused by deliberate alteration or modification of the laminate (such as customer-applied tints or films)
  • Minor scratches
  • Excessive artificial temperature build-up or exposure, including, for example, that caused by using windows or shutters
  • Damage from windborne debris associated with severe acts of nature, such as earthquakes or tornadoes, fire, and flooding
  • Accidental or intentional damage over which Viwinco has no control (such as crime)
