Fire stopping in Elmdon, done properly
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. The enquiries we see most involve fire-rated sealant that has cracked or shrunk back and snag lists that include open service penetrations, on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows. Most enquiries from Elmdon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a smaller site near Elmdon, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Look above ceilings when tiles are lifted for other jobs
- Settle who seals which penetrations at the start of a project
- File the specified details where the next contractor can find them
- Keep general-purpose fillers away from compartment walls
Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Backing rod, priming and other preparation
- Phasing around occupants
- Site requirements such as inductions and permits
- How much there is to seal
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email a schedule or drawings.
FAQs: Elmdon
Can you work at a site such as Abbey Barns Business Park, by Elmdon?
Yes. We cover Elmdon and the area around it, including industrial estates, business parks and retail parks such as Abbey Barns Business Park. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Saffron Walden Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
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.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you seal openings left by new services?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. Where it isn’t required, we install the specified sealant to the maker’s details.
What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Plastic pipes whose detail calls for a collar or wrap
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Signs you need fire stopping in Elmdon
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Site and facilities staff are often the first to spot these:
- Openings left by services added after handover
- Seals that don’t match their tested detail
- Snag lists that include open service penetrations
- Non-fire-rated filler around services
For a building such as Church of St Nicholas, new heating or data runs are the usual reason penetrations need sealing.
Questions to ask before you book
- Who will actually carry out the work
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
- How the existing material will be dealt with
Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Elmdon are usually planned as a single visit, so photographs 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.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Advice
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Compartment walls and floors in Elmdon
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. Elmdon is about 38 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
On a hospital site such as Saffron Walden Community Hospital (5.3 miles east of Elmdon), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. On a site such as Abbey Barns Business Park, 2.9 miles north-east of Elmdon, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
