5 Years Guarantee on selected products
5 Year Guarantee
All of our doors and hardware are guaranteed for five years against the occurrence of manufacturing faults.
The guarantee is conditional upon following and complying with the instructions and recommendations in our installation, care and maintenance instructions. This guarantee covers replacement of faulty parts only and does not cover incidental expenses.
Prefinished door sets
All fully finished door sets come with finish guarantees. However they must be well maintained and re-coated as and when necessary before the coating breaks down. Moisture must not be allowed to penetrate the timber during the life of the product. It is very important that the finish on your door set is checked every six months for deterioration, and re-coated if necessary. This will maintain the decorative finish and ensure that no moisture enters the timber of the doors and frames during the life of the product, giving long lasting performance. All our finish guarantees are offered in accordance with EN927/1-7.
Treating unfinished door sets
All our unfinished doorsets come with a 3 month guarantee subject to the following guidelines. We recommend finishing unfinished exterior door sets with a high build microporous wood coating system. This should consist of one coat of base stain and two coats of top coat, in a wood stain or paint colour of your choice.
After delivery, doorsets should be stored in a dry location, with doors and frames stored flat, slightly raised from the ground to ensure adequate air circulation. They MUST be decorated as soon as possible after delivery to stop moisture imbalances. All surfaces and edges of the doors and frames (even the back) must be coated with these three coats to adequately protect the timber and stop moisture getting in. The finish must be regularly maintained to ensure moisture does not penetrate into the timber during the life of the product. All surfaces must be treated/sealed at the same time to prevent distortion from moisture imbalance. Important: Unfinished sets must be decorated in accordance with British Standard Code of Practice BS 6150:1991 Painting of Buildings and BS 8000 Part 12 1989 – BEFORE the door set is installed. Failure to do so will invalidate the guarantee. We do not recommend finishing with Danish oil, wax or any finish other than a medium to high build microporous wood finishing system. Please note that the use of steel wool, or allowing steel or iron fragments to come into contact with the untreated oak timber or veneers may cause oxidation resulting in black stain. Green Tree Doors will not take responsibility for any inappropriately decorated products and any faults arising therefrom.
