Frequently Asked Questions

Hardwood doors are made from natural timber and need treating with exterior wood stain every 2 to 3 years. GRP composite doors look like timber but are made from glass-reinforced polyester — they never need painting, are weather-resistant and dent-resistant. Composite costs more upfront but saves on maintenance long term.

Most of our glazed external doors come with double glazing as standard. This includes hardwood, oak and GRP composite glazed doors. Unglazed doors are also available if you prefer to source your own glass or want a solid panel design.

Yes, we offer both supply only and supply and fit. If you have your own builder or want to fit the door yourself, we can supply it at the door-only price. For supply and fit, our joiners handle everything including removal of the old door, trimming, hanging and fitting locks.

We recommend treating unfinished hardwood doors with a solvent-based microporous exterior wood stain before installation, and retreating every 2 to 3 years. Avoid water-based products as they can affect the warranty. GRP composite doors just need a wipe down with soapy water.

A straightforward external door replacement typically takes half a day. If the frame needs replacing or adjusting, it may take a full day. Our joiners will advise during the free home survey and give you an accurate time estimate before any work starts.
