What type of security guarantee do you offer on your exterior doors?

Good locks are essential on any exterior door, which is why we fit the very best ERA multi-point systems as standard on our complete doorsets.

For added safety, you can upgrade any of our doorsets to meet the requirements of the police approved Secured by Design scheme and Approved Document Q of the Building Regulations. Our INSULUX exterior doorsets come with this as standard.

Are handles included with my exterior doors?

Handles will be included when you order one of our complete doorset products. We don’t supply handles with our single (without frame) exterior doors such as our white oak doors. 

How do I maintain exterior doors?

This is a checklist we recommend you do a minimum bi-annually. For coastal areas and places where pollution is high we recommend a minimum of four times per year.

  • All joinery (including GRP composite doors) should be washed down a minimum of twice a year with a mild solution of soapy water and rinsed off with clean water to remove any surface debris. 
  • All hinges and locks should oiled with grease or neutral oil. All handles and letterplates should also be regularly cleaned to remove any environmental deposits – in coastal areas this might be required weekly
  • For timber doors once cleaned, lightly sand and touch up any areas of wear and tear with a matching microporous paint or stain. Any bare wood should be primed first. Your factory finished painted product should last in line with our guarantees up to 10 years for white painted under normal conditions and if kept clean and correctly maintained.

Always check fitting instructions supplied with the doors for full details.
