How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In Thornton Heath, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
- Arrange parking or a loading space

Fire stopping in Thornton Heath
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. Those on your schedule are closed with the specified product. Site teams most often ask us about expanding foam used as fire stopping and fire stopping installed outside its tested range, across pipe penetrations, cable penetrations and service gaps in risers. A specialist sealant contractor works differently from a general builder: in Thornton Heath, that means joint design, primers and backing rod as standard.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Linear joints
Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Joint width, depth and condition
- The total length or number of joints
- Site requirements such as inductions and permits
- Distance, for remote addresses
We don’t publish prices, since every building and every scope is different. Call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The site address and postcode
- What the building is and how it’s used
- Your programme or deadline
- Clear photographs of the problem areas
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email the details over.

Why act early in Thornton Heath
The longer openings stay, the more there tend to be: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Getting scaffold, permits or access booked in Thornton Heath takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Common questions from Thornton Heath clients
Can you work on a hospital site such as Croydon University Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you reseal penetrations after our M&E works?
Yes. Send the schedule or marked-up drawings and the specified product details. We can follow the services contractor floor by floor so areas aren’t left open.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
What do BS EN 1366-3 and BS EN 13501-2 mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Settle who seals which penetrations at the start of a project
- Foam or ordinary sealant is never a fire-seal repair
- Check risers and ceiling voids after each round of works
- Have penetrations checked while they can still be seen
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned.
Fire stopping around Thornton Heath: points for this area
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. What we install is set by the specification, and it goes in to the tested detail. With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
At a college such as Spurgeon's College, 1 mile to the north-east of Thornton Heath, checking penetration seals after summer M&E works is good practice. In a retail centre such as Whitgift Centre, 1.7 miles to the south of Thornton Heath, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. On estates like Thornton Road Industrial Estate, 1 mile south-west of Thornton Heath, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
