When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.
Joints and surfaces we work on
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
How we handle fire stopping in Cramhurst
Facilities managers in Cramhurst 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. With no specification in place, the first step sits with your designer or fire engineer, not with us. Site teams most often ask us about fire-rated sealant that has cracked or shrunk back and head-of-wall gaps with no fire seal, across joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Cramhurst, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Cramhurst often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
Fire stopping around Cramhurst: what changes locally
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.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. Cramhurst lies roughly 34 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
At a healthcare site like Milford Hospital, 1.4 miles east of Cramhurst, new services through compartment walls are a constant, and each needs the specified seal. For a building at a site such as Godalming Business Centre, 2.8 miles north-east of Cramhurst, a check of penetration seals after each fit-out is good practice.

Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
FAQs: Cramhurst
What does the BS 476 change mean for fire-rated sealant in Cramhurst?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
Can you work at a site such as Godalming Business Centre, by Cramhurst?
Yes, sites like Godalming Business Centre are within our area, along with the rest of Cramhurst. A few photos and the unit address let us price the work.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Cramhurst can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Send your site hours and access windows
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Leave fire sealant to cure fully before covering it
- Flag new cables with no seal around them
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Have penetrations checked while they can still be seen
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Signs you need fire stopping in Cramhurst
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
If one of these sounds familiar, it’s time for a closer look:
- Fire-rated sealant that has cracked or shrunk back
- Openings found when ceilings come down for a refit
- Unsealed openings around new pipes and cables
- Damaged fire seals in risers and voids
Hotels like The White Hart Hotel, 0.9 miles to the south-east of Cramhurst, are refurbished in phases, and each phase can open up compartment walls.
