Fire stopping in Writtle
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. Most enquiries involve snag lists that include open service penetrations and service penetrations left open after M&E works, on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Writtle first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fire-rated sealing in a place like Writtle is typically a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Why it’s worth doing now in Writtle
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Small buildings around Writtle suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Penetration seals near Writtle
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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.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. Writtle lies roughly 27 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.
For a site team at a college like Chelmsford College - Moulsham Street Campus, which lies east of Writtle, fire-rated sealing is best scheduled after the summer works. Older community buildings such as Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Writtle is about 3 miles west of Chelmsford, in Essex. We cover commercial sites throughout Writtle. Our Essex coverage takes in 644 places, from busy centres to rural villages. For work in that direction, see our London page (27 miles or so).

If your building is just outside Writtle, we cover Widford (2 miles south-east), Moulsham (2 miles east), Chignall St James (2 miles north), Patching (2 miles north-east) and Chelmsford (3 miles east).

Common problems we fix in Writtle
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Things that typically lead to an enquiry:
- Head-of-wall gaps with no fire seal
- Fire sealant pulled out of the opening
- Improvised or mixed-product fire seals
- Expanding foam used as fire stopping
Theatres, wards and plant rooms at sites like Chelmsford and Essex Hospital (1.7 miles south-east of Writtle) all have compartment walls crossed by services.
Comparing quotes
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Distance, for remote addresses
- Working within restricted access windows
- Joint width, depth and condition
- Site requirements such as inductions and permits
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- What the building is and how it’s used
- Any specification or named product
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email us if you’d rather talk the job through.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Writtle, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints

Advice
Common questions from Writtle clients
Can you work around term dates at a campus such as Anglia Ruskin University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is a smaller place like Writtle outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email us. Include photographs or drawings if you have them.
Can you fire stop behind the services contractors?
Yes. Share the penetration schedule and product details. Work can run area by area behind the M&E trades keeping pace with the programme.
