Our extensive research and development has led to the development of the best window in the industry. You can feel secure in the knowledge that our windows are manufactured and installed by the finest technicians and craftsmen. We are so confident that your Fersina windows will perform to the highest possible standards that we are issuing a lifetime warranty for Fersina manufactured products. Fersina Windows warrants that the product shall remain free of defects, in material or workmanship under normal use and service.

  • All vinyl extrusions will be warrantied against chipping, cracking, peeling, blistering, warping or sagging.
  • All window hardware balances, locks, keepers and casement operating hardware will be warranted to operate properly and serve the design function.
  • All glass units are warranted against seal failure, which results in dust, film or condensation forming between the panes of glass.
  • Glass units are fully guaranteed against spontaneous glass breakage for the lifetime of your ownership.
  • Window screens are covered for the full term of the warranty. Screen fabric, under normal use, is covered for ten years. Screen repairs are performed free of charge when returned to Fersina.

  • This warranty includes only those products manufactured by Fersina Windows. Non-Fersina products are covered by their manufacturer’s warranties.

Condensation on the glass surface is the natural result of excessive moisture in the home and does not indicate a defective product or faulty installation.



  • Defects or damage caused by fire, flood or “acts of God.”
  • Defects or damage caused by accidents, misuse, neglect or actions of others.
  • Products which have been altered or repaired by anyone other than an authorized Fersina service technician in a manner which has affected the performance or stability.
  • Caulking.
  • Service required beyond a 75km radius of Fersina Windows, may be subject to mileage fees at the discretion of Fersina Windows.



Your Fersina Window warranty can be transferred to future purchasers of the original property subject to a registered letter being sent to Fersina Windows. Notification must be received by Fersina Windows within 30 days of the new homeowner/s taking possession of the property where the Fersina product was installed. This warranty will expire should the new owner fail to send Fersina Windows notification within the time period noted above.
