Fire rated sealant in Churchgate
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. We work on flats & HMOs, door frames and service penetrations, and people most often call us about door frames with gaps between frame and wall and open joints along the top of partitions.
In a smaller place like Churchgate, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of gaps, and longer for a whole building. A visit to Churchgate is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Advice
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Doors that aren’t fire doors in the first place
- A wall that is not a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Your questions about fire rated sealant in Churchgate
Can you do fire rated sealant in Churchgate?
Yes. We work across London and the South East, and Churchgate is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you cover smaller places like Churchgate?
Yes. Churchgate is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you give us a record of the work?
Yes. We note each location and the product that went in, so you have it on file.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a smaller place like Churchgate, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Different surfaces, different methods
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.
Fire rated sealant around Churchgate
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Dewhurst St Mary CofE Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Theobalds Grove station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
