Common questions in Hertfordshire

Can you fit just one door in Harpenden?

Yes — from a single door to a full building. Where possible, small jobs are scheduled alongside other visits in Hertfordshire.

Can you work around tenants or staff in Harpenden?

Yes. We phase work in occupied buildings and keep escape routes available. Each door is planned to be removed and replaced the same day; if that isn't possible, the opening is made secure and we tell you in advance.

Do you cover Harpenden?

Yes. We survey, supply and fit glazed fire doors throughout Harpenden and the rest of Hertfordshire, including AL5 and nearby St Albans.

Is wired glass still used?

Rarely now. Modern clear fire-resistant glass gives much better visibility.
