What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like Compton, 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.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

About our fire stopping in Compton
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. If you have openings found when ceilings come down for a refit and seals disturbed by maintenance and left open, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Compton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Barn and farm-building conversions near places like Compton 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.

Questions about Compton
Is a smaller place like Compton outside your area?
No. Places such as Compton are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is hospital work, at somewhere like Wessex Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you tell us what fire stopping our building needs?
No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.
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, so we check each one.
Cost factors for service penetrations
We price every job individually. The things that drive the figure:
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- The product specified
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The product your specification calls for
- Access details, including height
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email the details over.
From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Compton are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- 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.
Preparing the site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Point out any areas we must not close

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
- Reviewing a building’s overall fire safety
If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

Service penetrations in Compton buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 63 miles from central London, Compton is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
Halls and meeting rooms at places like Church of All Saints sometimes gain new services, and any compartment wall crossed needs the specified seal. Residences at universities like University of Winchester (2.7 miles north of Compton) have compartment walls that must be resealed whenever services change.

When to call us in Compton
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. Across several fit-outs, the openings add up.
These are often picked up first by site or facilities staff:
- Openings left by services added after handover
- Old intumescent sealant that has split away
- Expanding foam used as fire stopping
- Seals that don’t match their tested detail
For a school such as Compton All Saints Church of England Primary School, penetration sealing fits best at the end of the summer works.
