Before you start

Your Seadec door and accessories (frames, skirting & architrave) must be stored flat on a clean, dry and level surface, with level battens to allow the air to circulate. To allow your door and accessories to acclimatise to their environment, they should be left in the house, for at least 7 days, with the heating and environment regulated per installation guidelines below. Doors should be stored flat. Environmental and door moisture readings should be taken prior to hanging and recorded, to ensure that the doors and the environment are in correct. Failure to allow the doors to acclimatise may cause excessive expansion and contraction leading to splitting and warping and will void the guarantee.

Unfinished or primed doors must be sealed and painted immediately after hanging with at least three coats applied.

Seadec doors and accessories must not be installed into a house that is freshly plastered, tiled or painted, it is crucial that building is properly dried out and that heating and humidity in building are stable before doors or accessories are brought on site or fitted, please ensure the building meets with the moisture and temperature guidelines below. Should a door require alteration, cutting or planing, it must be immediately varnished with three coats, otherwise it will absorb moisture which can lead to problems such as warping or splitting. Seadec doors may be altered by up to 10mm off the top and bottom and up to 7mm on each side only. However, any alteration of a Seadec door will void the warranty. For Fire Door alterations, please consult the relevant fire certificate.

Where doors are manufactured with solid timber, there has to be a consideration that timber will adjust itself to the environment. Therefore, please note that there is a BS standard of +/- 4mm of a bow tolerance on the length of a door.
