Fire stopping for Overton sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Fire stopping for commercial buildings in Overton
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. The enquiries we see most involve penetration schedules that need working through and hidden openings found during inspections, across small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers. Searching for sealant specialists in Overton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Converted and extended buildings around places like Overton can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we will come back to it.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For a job in Overton, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
What we need from you
- Tell staff and tenants when we will be in
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email drawings and photos.

Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- Which sealant the job calls for
- Working within restricted access windows
- Any access equipment needed
- Backing rod, priming and other preparation
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Any dates the work must fit around
- What the building is and how it’s used
- The asbestos register, for older buildings
- Clear photographs of the problem areas
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email drawings and photos.
Compartments and services around Overton
For England, the fire stopping of penetrations is dealt with in 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. Our part stays the same: the specified product, installed to its tested detail. Central London is about 53 miles from Overton. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Fire risk assessments, a job for a competent assessor
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Walls or floors that aren’t fire-resisting to begin with
If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
For managing agents and facilities managers
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
FAQs: Overton
What happens to BS 476 references for fire stopping in Overton?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is Overton too far out for you?
Not at all. Overton is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
What we’re called out for in Overton
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Typical triggers for a call:
- Seals disturbed by maintenance and left open
- Unsealed joints where partitions meet the slab
- Seals that don’t match their tested detail
- Penetration schedules that need working through
For a school such as Overton Church of England Primary School, penetration sealing fits best at the end of the summer works.
Questions to ask before you book
- How joint depth will be controlled
- How the existing material will be dealt with
- Who will actually carry out the work
- Can the work be phased to keep areas open?
