Leave it or put it right?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these and the building feels the difference. For buildings around smaller places like Bower Heath, 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. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Fire stopping in Bower Heath, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about hidden openings found during inspections and expanding foam used as fire stopping, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Whoever orders the work in Bower Heath, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Bower Heath often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
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 spell out the cover before we begin.

How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables.
Questions about Bower Heath
Can you work around term dates at a campus such as University Of Bedfordshire?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What does the BS 476 change mean for fire-rated sealant in Bower Heath?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
What do you charge?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
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 will arrange a visit before quoting.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire risk assessments, a job for a competent assessor
- Signing off or certifying a building’s fire stopping
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Joints and surfaces we work on

Quoting for work in Bower Heath
Your fixed quote is built from the real scope. It takes account of:
- Phasing around occupants
- Removal of failed or old sealant
- Distance, for remote addresses
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- The product your specification calls for
- The postcode of the building
- What the building is and how it’s used
- How the joints are reached, and at what height
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Bower Heath, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Arrange parking or a loading space
- Tell staff and tenants when we’ll be in
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Service penetrations in Bower Heath buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Either way, we install the specified product to its tested detail. Central London is about 26 miles from Bower Heath. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Schools such as Sauncey Wood Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. At a university such as University Of Bedfordshire, 4 miles north-west of Bower Heath, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a hospital such as Spire Hospital, which lies south-west of Bower Heath, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.
