Choices you can make
- Roller, carriage and hinge adjustment after fitting
- Anti-lift and lock checks on sliding doors
- Integral blind units replaced like for like where possible
- Glass lifters and enough installers for heavy panes

Towns in Cornwall
Before the glass is ordered
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
Door hardware
Glass is only part of the picture. Worn rollers, missing anti-lift blocks or old locks are often worth fixing at the same visit.
Glazing rules in England
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.

Patio and bifold door security glass in Cornwall: questions
Which towns in Cornwall do you cover?
We can arrange work anywhere in Cornwall, including Redruth, Falmouth, St Austell, Truro and Camborne, and in other towns across the area.
Is patio door glass already safety glass?
It should be, because doors are critical locations. Most is toughened, which is safe but not secure. Adding a laminated pane makes it both.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
Can sliding doors be lifted out?
Older sliding doors without anti-lift blocks can be. We check for this at the survey and can fit blocks at the same visit.
