How we handle fire stopping in Clapgate
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Clapgate and nearby. If you are dealing with improvised or mixed-product fire seals and builders’ foam or ordinary silicone in compartment walls, we can help. Searching for sealant specialists in Clapgate? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
A job near Clapgate is usually planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Large openings beyond what any sealant detail covers
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Cable penetrations
Service penetrations in Clapgate buildings
Clapgate is about 29 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
Hospital estates such as Herts and Essex Hospital, 4.2 miles south-east of Clapgate, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a unit at a site such as Hadham Industrial Estate, 1.3 miles south of Clapgate, new power or data runs between office and warehouse can breach a compartment wall.
Clapgate is about 4 miles north-west of Bishop's Stortford, in Hertfordshire. Anywhere in SG11, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Do you need fire stopping in Clapgate?
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.
Look out for the following:
- Hidden openings found during inspections
- Expanding foam used as fire stopping
- Damaged fire seals in risers and voids
- Openings left by services added after handover
For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- How the joint faces will be prepared and primed
Surface by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.
Cost factors for service penetrations
Your fixed quote is built from the real scope. It takes account of:
- Removal of failed or old sealant

Questions about Clapgate
Is Clapgate off your patch?
Not at all. Clapgate is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Hadham Industrial Estate, close to Clapgate?
Yes. Estates, retail parks and business parks around Clapgate, Hadham Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How much does the work cost?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.
What changes on 2 September 2029?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. Scotland follows its own Technical Handbook.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Clapgate are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Send your site hours and access windows
- Make sure the joints can be reached
- Let building users know which areas are affected
