Different surfaces, different methods
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
How we handle fire stopping in Shenfield
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls, on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Whoever orders the work in Shenfield, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Around Shenfield, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

Cost factors for service penetrations
These are the things that shape the price:
- Working within restricted access windows
- Travel to remote or island sites
- How accessible the joints are
- The size and state of each joint
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
Details that help us quote
However big the job, these details speed things up:
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
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 use the quote form.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations

Fire stopping in Shenfield: the local picture
At about 20 miles from central London, Shenfield is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds 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. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Holiday works at schools like Shenfield St. Mary's Church of England Primary School often leave service openings to seal before pupils return. Theatres, wards and plant rooms at sites like Brentwood Community Hospital, 0.5 miles to the south of Shenfield, all have compartment walls crossed by services. Hotels such as Brentwood Hotel, 1.3 miles to the south-west of Shenfield, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Aftercare for building managers
For the best life from the joints:
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
- Settle who seals which penetrations at the start of a project
- Include service cupboards in routine inspections
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Common questions from Shenfield clients
Is Shenfield too small for you to travel to?
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.
Can you work in a care home near Shenfield with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Do you hold third-party fire-stopping installer certification?
No. We don’t hold a third-party fire-stopping installer certificate. 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.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you design or specify fire stopping?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.
How many days will you need on site?
It depends on the scope, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
