Looking at triple glazed composite front doors for a home in Carrickfergus? We survey, quote and fit across County Antrim, and the BT38 postcode district is part of that.

Winter light and glass choice in Carrickfergus

Rules for composite front doors in Northern Ireland
In Northern Ireland, replacement external doors must meet 1.8 W/m²K. Replacing external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Planning: Check with your council planning office before changing the style, material or size of doors, and always for listed buildings, conservation areas and flats.

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- 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
