What to think about first

Integral blinds

Units with blinds inside the glass can be made with a laminated pane, but lead times are longer.

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.

Replacing glass in an existing frame

Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

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.

Patio and bifold door security glass in Hertfordshire: questions

Which towns in Hertfordshire do you cover?

We can arrange work anywhere in Hertfordshire, including Watford, Hemel Hempstead, Stevenage, St Albans and Welwyn Garden City, and in other towns across the area.

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.

Will laminated glass make my bifolds harder to open?

Units are slightly heavier. We adjust hinges, rollers and carriages after fitting so the doors run smoothly.

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.
