Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Writing the fire-stopping specification
- Approving the work on behalf of building control
- Openings that need collars, wraps, batts or boards rather than sealant
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
Surfaces we seal
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
Fire stopping in South Merstham, done properly
Facilities managers in South Merstham often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. If you have snag lists that include open service penetrations and old intumescent sealant that has split away, we can put it right. One point of contact handles commercial sealant work in South Merstham from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In places the size of South Merstham, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What else we do in South Merstham
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
- Joint width, depth and condition
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Where services cross fire walls in South Merstham
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 17 miles from South Merstham. 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.
Halls and meeting rooms at places like All Saints' sometimes gain new services, and any compartment wall crossed needs the specified seal. For a site team at a college like Reigate College, 2.7 miles south-west of South Merstham, fire-rated sealing is best scheduled after the summer works.

Your questions answered
Can work at a site such as Reigate College fit around teaching?

Do you cover business parks and estates near South Merstham, such as Kingsfield Business Centre?

How much does the work cost?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email a schedule or drawings.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details for a fixed quote. Work can run area by area behind the M&E trades.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically 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. What matters most for a job in South Merstham is a clear list of what needs doing. You will then get a fixed price for the work.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- 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.
Preparing the site
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we will be in
- Make sure the joints can be reached
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Advice
Signs you need fire stopping in South Merstham
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
Most enquiries start with one or more of the following:
- Hidden openings found during inspections
- Service penetrations left open after M&E works
- Old intumescent sealant that has split away
- Fire seals cut back for extra cables and never reinstated
At a healthcare site like East Surrey Hospital, which lies south of South Merstham, new services through compartment walls are a constant, and each needs the specified seal.
Questions to ask before you book
- Their public liability cover
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
- How joint depth will be controlled
