Triple glazed sealed unit replacement in the Highlands and Islands
Homes across the Highlands and Islands, including Inverness, Stornoway and Dingwall, can have triple glazed replacement sealed units measured, made to order and fitted. Island and remote districts are by arrangement, with travel and access costs shown separately on your quote.
Triple units for frames that can take them; better double units when they cannot. Sealed unit replacement means changing only the glass in an existing frame.

Rules in Scotland
In Scotland, replacement windows must meet 1.6 W/m²K. Replacing a window or door, frame and all, does not need a building warrant, but the work must still meet the building standards.
Planning: Since May 2024, replacement windows on houses are widely permitted development, including in many conservation areas, with front elevations expected to match the existing closely; your council tells you if prior notification applies. Flats outside conservation areas generally need permission only if the opening size changes. Listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions
Will heavier glass damage my hinges?
It can. Triple units are about 50% heavier, so hinges and packers are checked and upgraded where needed.
Can I put triple glazing in my existing windows?
Usually not in a way that helps. Most frames take up to about 28 mm units; a triple unit that thin performs about the same as, or worse than, good double glazing. We check your frames before recommending anything.
Why are my windows misting between the panes?
The seal around the unit has failed and moist air has got in. Only replacing the unit fixes it.
Do you cover all of the Highlands and Islands?
We arrange surveys and fitting across the Highlands and Islands. Island and remote districts are by arrangement, with travel and access costs shown separately on your quote.
Do I need permission for triple glazed replacement sealed units in Scotland?
In Scotland, replacement windows on houses are widely permitted development since May 2024, with front elevations expected to match closely; listed buildings need consent.
