Warranty and Guarantee Details

What does the Warranty Cover?

The Warranty provided with our products covers various elements of the product for varying amounts of time. As third party products are used as part of our products, these items are covered by the 3rd party manufacturer. The individual product warrantees are described below

Joinery Elements

Aspects of the product which are manufactured and fully finished by CHT Joinery are covered by a 10 year warranty against defects and failure. These include but are not limited to timber framing sections, sash assemblies, staircases and glazing beads. These are covered under the warranty as long as the following criteria is met.

  • The frames have not been subjected to damage, misuse or usage not intended for the purpose it was supplied for.
  • The joinery is not submerged in water or in an environment it was not designed and supplied for.
  • Maintenance cycles have been upkept regarding cleaning and painting in line with the paint manufacturers instructions. Please ask for manufacturer and maintenance cycle for paint systems used on your product. In heavily weathered locations and elevations maintenance cycles are reduced and need to be maintained on a more frequent basis.

All external joinery is preserved and end grain sealed prior to any coat system even on unfinished products. The 10 year guarantee does not cover against Rot as this is related to use and maintenance of the paint systems used which are the responsibility of the owner/customer.

All external joinery which is unfinished holds a 5 year guarantee against defects and failure provided the above criteria are met.



Glazing is supplied with a 5 year warranty via our supplier. The warranty covers double or triple glazed units provided they meet the following criteria.

  • The units have been installed as recommended by the supplier. If CHT Joinery has provided preglazed joinery then our supplier is happy to honour the warranty. If glazing is installed via a third party then our supplier may need proof of the breakdown and the method of installation. If units are installed incorrectly the warranty is void. CHT Joinery accepts no responsibility for units installed by 3rd parties. Details for correct installation are available on request or via our suppliers website. Please ask for details or see website.
