3. Minor invisible from 1, 5 metre  distance paint imperfections are permitted. 

4. No guarantee given for any door panels if doors open outwards and if there is no full protection from weather influence.

5. 10 years external flat panels only guarantee from twisting or splitting , if the Medite Tricoya extreme MDF option is chosen. Starting from an additional £125+VAT per standard size door, this option is recommended for glazed doors and side panels only.


EXTERNAL DOOR PANELS : ( Victorian , Georgian , 1930'S  with intricate beadings ussually made from wooden mouldings , marine plywood or Medite Tricoya  )


1. Door sets with intricate wooden , Medite MDF  , okoume or other plywood mouldings ( usually Victorian, Georgian and Edwardian styles ) dark , especially glossy dark colour finishes are NOT covered with a warrantee against intricate moulding edge or mitre cracking. To slow down this process full protection from weather influence for that kind of door is required.

2.Please consider carefully before choosing traditional designs as they always require more maintenance than flat carved designs.

3.Please visit our show room to view the glossy finishes we offer, and keep in mind that a shiny door needs very high and scheduled maintenance to keep it this way.




1. As a natural product, even the best  timber door mouldings may experience some movement in all planes, movement within the published British standards will not constitute a defect. The guarantee does not cover the paint finish, some variation should be expected and small cracks on joints and in the face, whilst rare, are not unexpected or of structural concern. These should be filled and repainted with the touch up paint provided. 

2. Please note that dark doors eg. black especially with a gloss finish will fade and beadings will experience alot of movement if fitted in direct sunlight and rain. 

3. All traditional door external panels are made from more than 15 pieces of Wood EDM or Marine Plywood depending on choice . Due to unstable nature of these materials , weather,  and high vibration when door is in use , smaller or bigger cracks will appear sooner or later , if door is unprotected from weather influence please fill up those gaps with filler ASAP , acrylic sealant or silicone to stop water getting in deeper and creating bigger damage.

4.To keep the finish smooth and shiny ensure no abrasive materials or chemicals are used to clean your door. Microfibre cloth with some soapy water and glass cleaner for glass parts is more that enough to keep your door clean. 


The good news is that even if the external panel is damaged by weather or vandals it will NEVER impact your door steel structure , locking or functionality. You will remain safe in your home.           

All our door panels can be sanded,  filled and painted many times like any wooden door.
