Fire stopping in Ewhurst
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and hidden openings found during inspections. Searching for sealant specialists in Ewhurst? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Rural conversions around Ewhurst can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
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’re clear about what is covered before work starts.

Why act early in Ewhurst
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. For buildings around smaller places like Ewhurst, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Cables and cable bundles
New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
Fire-rated sealing for Ewhurst buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail. Ewhurst lies roughly 28 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a school such as Ewhurst CofE Aided Infant School, penetration sealing fits best at the end of the summer works. Halls and meeting rooms at places like Church of St Peter and St Paul sometimes gain new services, and any compartment wall crossed needs the specified seal. Where a unit on an estate such as Manfield Park Industrial Estate, 2.8 miles to the west of Ewhurst, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Ewhurst is about 7 miles south-west of Dorking, in Surrey. Businesses, contractors and managing agents in Ewhurst can call on us for service penetrations, as part of our coverage of Surrey.

Building owners, agents and FMs in Ewhurst
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Doing it in-house
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Ewhurst, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected

Questions we’re asked in Ewhurst
What does the BS 476 change mean for fire-rated sealant in Ewhurst?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is Ewhurst off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Gaps in walls that were never built as compartment walls
- Reviewing a building’s overall fire safety
- Approving the work on behalf of building control
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.
