Triple glazed sliding patio doors in Dumfries and Galloway
We survey and fit triple glazed sliding patio doors across Dumfries and Galloway, from Dumfries and Stranraer to smaller towns such as Lockerbie.

More glass, less cold: sliders that stay comfortable in winter. A sliding patio door has large glazed panels that slide past each other on a track, so it opens without swinging into the room.

Rules in Scotland
Scotland sets replacement door limits through the Building Standards Technical Handbook (Domestic), section 6: 1.6 W/m²K. Replacing a door or window, frame and all, does not need a building warrant, but the work must still meet the building standards.
Planning: A replacement door on a house that looks similar to the existing one is generally permitted development; check with your council for flats and conservation areas, 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
Are triple glazed sliding doors hard to open?
Not with correctly rated rollers. Lift-and-slide gear makes even very large panels easy to move.
Do sliding doors need safety glass?
Yes, all door glass must be safety glass. Triple units in sliders are toughened or laminated.
Can I have a level threshold?
Low thresholds are available; they need a suitable drainage detail outside, which we check on survey.
Do you cover all of Dumfries and Galloway?
We arrange surveys and fitting across Dumfries and Galloway.
Do I need permission for triple glazed sliding patio doors in Scotland?
In Scotland, a replacement door on a house that looks similar is generally permitted development; check with your council for flats and conservation areas, and listed buildings need consent.
