Our process
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near Broxbourne can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Send your site hours and access windows
- Warn occupants and staff about the work
- Point out parking and an unloading spot

Fire stopping in Broxbourne, done properly
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you have fire stopping installed outside its tested range and fire-stopping items raised at inspection or handover, we can put it right. Looking for mastic applicators who cover Broxbourne? We have been sealing commercial buildings since 2005.
In places the size of Broxbourne, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Broxbourne. Several sites can go on one quote, which keeps the paperwork simple.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Common problems we fix in Broxbourne
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Common reasons buildings call us in:
- Snag lists that include open service penetrations
- Fire stopping installed outside its tested range
- Open linear gaps along the top of fire-resisting walls
- Damaged fire seals in risers and voids
For a hospital such as Hertford County Hospital, 4.3 miles north-west of Broxbourne, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Before you book anyone
- Will CSCS-carded applicators be on site?
- What the guarantee covers, and for how long
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Construction that lacks the fire resistance the seal relies on
- Fire risk assessments, a job for a competent assessor
- Signing off or certifying a building’s fire stopping
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
What we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Pipe penetrations
Service penetrations in Broxbourne buildings
Broxbourne lies roughly 18 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; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For a site team at a college like Hertford Regional College, 1.2 miles to the north of Broxbourne, fire-rated sealing is best scheduled after the summer works. Hotels like The Bell Hotel and Tea Rooms, 1 mile to the north-east of Broxbourne, are refurbished in phases, and each phase can open up compartment walls.

Broxbourne: questions and answers
Will you plan work around the academic year at somewhere like Hertford Regional College?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a hospital such as Hertford County Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
What do BS EN 1366-3 and BS EN 13501-2 mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.
