Fire stopping in Ewell, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about expanding foam used as fire stopping and fire-stopping items raised at inspection or handover, across linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ewell, that means joint design, primers and backing rod as standard.
Towns the size of Ewell have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. Whenever new services go through those walls, the gaps need sealing with the specified product.
Our 12-month guarantee is about workmanship, not 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.

After the work
Once the work is signed off, these steps help:
- Don’t let anyone top up a fire seal with the wrong product
- Settle who seals which penetrations at the start of a project
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Town-centre premises in Ewell may have limited parking, so tell us what’s nearby. On estates and business parks it’s normally simpler.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints
- Tell us your opening times and when work is allowed

What else we do in Ewell
What the job involves on each surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. For businesses and landlords in Ewell, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Service penetrations in Ewell buildings
The area within 2 miles of Ewell holds several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs 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. What we install is set by the specification, and it goes in to the tested detail.
Large healthcare estates like St. Ebba's Hospital (to the west of Ewell) change their services often, so penetration seals are worth checking after M&E work. For an estates team at a campus like University for the Creative Arts, 1.7 miles south of Ewell, summer M&E works are typically followed by a round of penetration sealing.

Questions we are asked in Ewell
Is Longmead Industrial Estate, near Ewell, within your area?
Yes. We cover Ewell and the area around it, including industrial estates, business parks and retail parks such as Longmead Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Is hospital work, at somewhere like St. Ebba's Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Signs you need fire stopping in Ewell
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
What tends to prompt an enquiry:
- Openings left by services added after handover
- Fire-rated sealant that has cracked or shrunk back
- Non-fire-rated filler around services
- Penetration schedules that need working through
For a unit at a site such as Longmead Industrial Estate, which lies south-west of Ewell, new power or data runs between office and warehouse can breach a compartment wall.
What your quote should include
- How the joint faces will be prepared and primed
- Will RAMS and insurance details be available?
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Ewell can sit alongside others in a wider programme.
