How we handle fire stopping in Crystal Palace
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance. Site teams most often ask us about unsealed joints where partitions meet the slab and fire-stopping items raised at inspection or handover, on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors. Whoever orders the work in Crystal Palace, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common questions from Crystal Palace clients
Can you seal around new services in a hotel near Crystal Palace?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Will you work in a care home in Crystal Palace 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.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Crystal Palace can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Send your site hours and access windows
- Send any specification or drawings in advance
- Tell us which areas need to stay in use

Maintenance after handover
To get the most from the new sealant:
- File the specified details where the next contractor can find them
- Check risers and ceiling voids after each round of works
- Keep general-purpose fillers away from compartment walls
- Leave fire sealant to cure fully before covering it
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
How the quote is worked out
Each job is priced on its own details. The main factors are:
- Which sealant the job calls for
- How much existing material needs removing
- Backing rod, priming and other preparation
- Travel to remote or island sites
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- The site address and postcode
- The type of building and who uses it
- How the joints are reached, and at what height
- Your programme or deadline
For a fixed quote, ring 01277 525 020 or email us. Our quote form is another easy route.
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
Service penetrations in Crystal Palace buildings
Crystal Palace has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Crystal Palace has four care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.
Residences at universities like King's College London, 3.5 miles north of Crystal Palace, have compartment walls that must be resealed whenever services change. Theatres, wards and plant rooms at sites like British Home & Hospital for Incurables, 1.6 miles to the west of Crystal Palace, all have compartment walls crossed by services.
Crystal Palace is about 2 miles north-east of Thornton Heath, in Greater London. We send applicators to Crystal Palace for service penetrations. 764 places across Greater London fall within our area, Crystal Palace among them. For work in that direction, see our London page.

Do you need fire stopping in Crystal Palace?
Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access typically bring them to light.
Most enquiries start with one or more of the following:
- Open linear gaps along the top of fire-resisting walls
- Unsealed openings around new pipes and cables
- Damaged fire seals in risers and voids
- Builders’ foam or ordinary silicone in compartment walls
For a site team at a college like Capel Manor College, which lies south of Crystal Palace, fire-rated sealing is best scheduled after the summer works.
