What FD30 fire doors in Thornaby-on-Tees should include
Our FD30 fire doors service covers Thornaby-on-Tees and the wider County Durham area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
In and around Thornaby-on-Tees, fire door work covers everything from care homes to small blocks of flats. We plan each job around the people who use the building.
Each FD30 leaf we supply for Thornaby-on-Tees is sized for the opening, rather than trimmed beyond what its certification allows. In Thornaby-on-Tees, FD30 doors are the usual choice for escape-route corridors, stairs and kitchen doors where the fire strategy asks for 30 minutes.
Where are FD30 doors used?
FD30 is the rating most buildings rely on. You will find it on flat entrance doors, doors onto escape corridors and stairs in houses in multiple occupation, kitchen doors in HMOs, and most internal doors on escape routes in offices, schools, surgeries and shops. Where smoke control matters too, the door is specified as FD30S (E30Sa), which adds a smoke seal and a tighter threshold.
The rating your building needs comes from its fire strategy or fire risk assessment, not from the door supplier. If you are unsure whether a door should be FD30 or FD60, we check the drawings, the risk assessment and what is installed now before we price anything. Our FD30 vs FD60 guide explains the difference.
What you get:
- Frame-to-wall gap sealed with an evidenced material
- Certified FD30 or FD30S leaf, or full doorset
- Overhead closer set to close and latch
- Fire-tested hinges, latch or lock and intumescent pads

Questions from Thornaby-on-Tees
Is Thornaby-on-Tees within your coverage area?
It is. We cover Thornaby-on-Tees in County Durham and neighbouring towns such as Stockton-on-Tees. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
What is the difference between FD30 and FD30S?
FD30S has been tested for smoke control as well as fire. It adds a smoke seal, usually a brush or blade, and needs a tight threshold gap. Flat entrance doors and doors onto protected escape routes are commonly specified as FD30S.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
