How much should I budget for patio and bifold door security glass in Caernarfon?
Budget £354 to £1,074 including VAT (£295 to £895 plus VAT) per pane for patio and bifold door security glass in Caernarfon, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Patio and bifold door security glass means fitting large sealed units with a laminated pane into sliding, French or bifolding doors. These doors are usually the biggest glass at the back of the house and out of view, so making the glass hold when it is struck closes one of the easiest routes in.
What you can specify
- Glass lifters and enough installers for heavy panes
- Anti-lift and lock checks on sliding doors
- Security tape on externally beaded frames
- Roller, carriage and hinge adjustment after fitting
- Integral blind units replaced like for like where possible
- Units sized for sliding, French and bifold doors

What to think about first
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
Laminated inner or both panes
A laminated inner pane is the usual security upgrade. On very exposed doors both panes can be laminated.
Consents and safety: Wales
Security rules for new homes
Wales introduced its own Approved Document Q for new homes, in force from 1 November 2018, and it applies to newly erected dwellings only. It follows a similar approach to England's, with PAS 24 referenced for easily accessible doors and windows and laminated glass to BS EN 356 P1A in doors and nearby windows. It does not apply to changing the glass in an existing home.
Planning permission
In Wales the local planning authority decides whether a new or altered shopfront needs planning permission. Replacing glass in an existing frame usually does not, because the outside of the building looks much the same. Bollards or barriers on the pavement need consent from the highway authority, normally the council.

Patio and bifold door security glass in Caernarfon: questions
Do you cover Bangor as well as Caernarfon?
Yes. As well as Caernarfon, we can arrange surveys in nearby Bangor, Pwllheli and Holyhead. Dates depend on installer availability.
Can you replace just one pane of a bifold?
Yes. Each leaf takes its own unit, so we can upgrade one leaf or all of them.
Do you work on aluminium bifolds?

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.
