FD30 fire door installation in Welwyn Garden City

Getting FD30 fire doors right in Welwyn Garden City

Our FD30 fire doors service covers Welwyn Garden City and the wider Hertfordshire area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.

Welwyn Garden City has a broad mix of buildings, including industrial estates, HMOs and family homes after loft conversions, and the same fire door principles apply to all of them.

Each FD30 leaf we supply for Welwyn Garden City is sized for the opening, rather than trimmed beyond what its certification allows. In Welwyn Garden City, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes.

Leaf only or a full doorset?

If the existing frame is sound, correctly sized, securely fixed and compatible with the new leaf's certification, a new FD30 leaf can be hung in it. Many frames do not pass that test: old softwood linings, frames that have been cut about for previous doors, or frames with no evidence of how they were fixed. In those cases a certified doorset (leaf, frame and ironmongery tested together) is the cleaner answer and usually the quicker one on site.

We tell you which route each opening needs on the survey, door by door, and why.

As standard, the work covers:

• Photo record, product data and certificate references at handover
• Overhead closer set to close and latch
• Intumescent strips and smoke seals to the certification
• Fire-tested hinges, latch or lock and intumescent pads
