Fire stopping for Bletchingley sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Maintenance after handover
After handover, a little attention goes a long way:
- Settle who seals which penetrations at the start of a project
- Check with the data sheet before painting over fire sealant
- Have penetrations checked while they can still be seen
- Foam or ordinary sealant is never a fire-seal repair
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Fire stopping for commercial buildings in Bletchingley
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance in Bletchingley and nearby. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and fire-rated sealant that has cracked or shrunk back, across service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Bletchingley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a smaller site near Bletchingley, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
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.

What else we do in Bletchingley
What happens if it’s left?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Around Bletchingley, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Jobs in and around smaller places like Bletchingley are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- 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.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Before we start on site
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000

FAQs: Bletchingley
Will you work in a care home in Bletchingley without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Can you seal penetrations in a hotel in Bletchingley after a refit?
Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is Bletchingley in your area?
Yes. Bletchingley is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or email a schedule or drawings.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Service penetrations in Bletchingley buildings
Central London is about 18 miles from Bletchingley. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Bletchingley has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
Theatres, wards and plant rooms at sites like North Downs Hospital (2.5 miles north of Bletchingley) all have compartment walls crossed by services. For a building at a site such as Brewerstreet Dairy Business Park, which lies north of Bletchingley, a check of penetration seals after each fit-out is good practice. For a hotel such as The White Harte Hotel (less than half a mile south of Bletchingley), penetration seals are worth checking after any refit or services upgrade.

Site staff or a sealant specialist?
Certain joints really need a specialist: 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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Plastic pipes whose detail calls for a collar or wrap
- Fire doors, dampers or other fire safety equipment
- Approving the work on behalf of building control
If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.
