Workmanship Guarantee

Where the works are registered with a Competent Person Scheme; this guarantee covers a breach of the Building Regulations in force at the time of the completion of the works.

Aftercare of your windows

Your finished timber product requires an ongoing maintenance program to be carried out.  As a minimum, you must clean your product with warm water and mild detergent every 6 months, this may need to be more frequent in areas of excessive algae & mould growth. (Never use abrasive materials to do this!)

If the paint film is damaged it must be repaired immediately with the same finishing system as originally supplied by Traditional Carpentry LTD.

After 5 years you will need to recoat your timber product(s).  

The durability and life expectancy of the coating system is dependent on the locality and environment into which the product is installed.  In areas of high corrosive atmospheric conditions (i.e. Coastal or industrial areas life expectancy of the paint system may be reduced).  Products that are installed in these types of locations may not be guaranteed for the full 6 years.  We would recommend that windows fitted in these areas are re-coated with microporous paint after 3 years.

All work in relation to, and including, this guarantee is provided in good faith. However, if it is discovered that the product has been tampered with, misused or negligently damaged by the customer, the guarantee shall not cover losses arising out of such instances. 

Under our terms and conditions all goods remain the property of Traditional Carpentry LTD until paid for in full. All guarantees only become effective once cleared funds are in our account.
