Fire stopping for commercial buildings in Highbridge
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have unsealed openings around new pipes and cables and builders’ foam or ordinary silicone in compartment walls, we can put it right, on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations alike. One point of contact handles commercial sealant work in Highbridge from the first photos to the final walk-round, whether it’s one building or several.
A job near Highbridge is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Questions we’re asked in Highbridge
Can you seal penetrations in a hotel in Highbridge after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Is a smaller place like Highbridge outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How much does the work cost?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email a schedule or drawings.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Smaller jobs around Highbridge can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Flag any permit to work we will need

After the work
For the best life from the joints:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
- Flag new cables with no seal around them
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What we’re called out for in Highbridge
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Typical triggers for a call:
- Fire sealant pulled out of the opening
- Unsealed joints where partitions meet the slab
- Hidden openings found during inspections
- Seals disturbed by maintenance and left open
Wherever services are added at a hospital such as Wessex Hospital (to the west of Highbridge) the compartment line has to be made good with the specified product.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How long is the guarantee, and what does it include?
- Whether primer will be used where the manufacturer specifies it
- Will failed sealant be removed rather than covered?
Cost factors for service penetrations
The price varies from site to site. It mainly depends on:
- The total length or number of joints
- How much existing material needs removing
- Backing rod, priming and other preparation
- Which sealant the job calls for
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Fire stopping around Highbridge: points for this area
Highbridge is about 64 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. 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. What we install is set by the specification, and it goes in to the tested detail.
Campus buildings at universities such as University of Winchester, 4.9 miles to the north of Highbridge, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. On a site such as Wessex Business Park, 0.9 miles to the east of Highbridge, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
