White French doors open from a kitchen-diner onto a sunny garden patio

A warmer kitchen-diner: less cold glass by the table. French doors are a pair of doors that open together, with no fixed centre post, usually leading to a garden or patio.

Winter light and glass choice in Weymouth

Winter days in Weymouth are short: about 7 h 58 min of daylight on 21 December, with the sun peaking near 16°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for french doors in England

England sets replacement door limits through Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.

Before ordering: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.

How it works

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • Every opening measured, including escape and vent needs
  • Frames rated for the weight of triple glass
  • Old windows removed and taken away
  • Each opening closed up the same day

Questions from Weymouth

Do I need planning permission?

Replacing an existing door on a house is normally permitted development. Making a new opening is a structural change that may need approval; flats and listed buildings have their own rules.

Can French doors be triple glazed in uPVC?

Yes, many uPVC door systems take triple units; the frame depth is checked on survey.

How long does it take to get triple glazed French doors fitted in Weymouth?

After the survey, typical manufacture time is 4 to 7 weeks, and a door is usually fitted in a day.
