Fire stopping in Fyfield, done properly
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations, and the failures we’re asked to look at most are non-fire-rated filler around services and improvised or mixed-product fire seals. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Fyfield, preparation and product choice get the time they need.
A job near Fyfield is typically planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Fyfield
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Clients typically get in touch after noticing one or more of the following:
- Unsealed openings around new pipes and cables
- Improvised or mixed-product fire seals
- Head-of-wall gaps with no fire seal
- Unsealed penetrations discovered above suspended ceilings
In a school such as The Ongar Academy, fire-rated sealant goes in around service penetrations where it is specified.

Compartment walls and floors in Fyfield
In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. At about 23 miles from central London, Fyfield is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What else we do in Fyfield
After the work
Keep the joints in good shape with a few simple steps:
- Get seals inspected before ceilings and boxing close
- Look above ceilings when tiles are lifted for other jobs
- File the specified details where the next contractor can find them
- Settle who seals which penetrations at the start of a project
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Fyfield, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
- Share the asbestos register for older buildings

What the job involves on each surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Questions we’re asked in Fyfield
What does the BS 476 change mean for fire-rated sealant in Fyfield?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you design a fire-stopping scheme for our building in Fyfield?
No. The designer or fire engineer sets the detail and building control accepts it. We install what’s specified, to the product’s tested detail.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you work in Fyfield?
Yes. Sites across Fyfield are covered, and the same phone number covers every area.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Approving the work on behalf of building control
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
