Fire stopping for Manor House sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
To price the job, we consider:
- Site requirements such as inductions and permits
- Phasing around occupants
- Whether old sealant has to be cut out first
- How much there is to seal
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Any specification or named product
- Any dates the work must fit around
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode

How we handle fire stopping in Manor House
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. 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 open linear gaps along the top of fire-resisting walls and fire-rated sealant that has cracked or shrunk back, on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Manor House is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Manor House, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and any bundle too large for sealant alone is flagged.
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, including keys, permits and any isolations.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Gaps in walls that were never built as compartment walls
- 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, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
Questions we’re asked in Manor House
Can you work on a hospital site such as St Ann's Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we’re not the right fit for that package.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Common problems we fix in Manor House
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Clients usually get in touch after noticing one or more of the following:
- Non-fire-rated filler around services
- Fire stopping installed outside its tested range
- Openings found when ceilings come down for a refit
- Fire seals cut back for extra cables and never reinstated
Hotels like Redland Hotel, less than half a mile to the south of Manor House, are refurbished in phases, and each phase can open up compartment walls.

- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Manor House, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Fire stopping around Manor House: what changes locally
The area within 2 miles of Manor House holds plenty of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. With tenants changing and fit-outs following, London buildings see service routes altered again and again. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Theatres, wards and plant rooms at sites like St Ann's Hospital (to the north-east of Manor House) all have compartment walls crossed by services. Campus buildings at universities such as American University in London (1.1 miles south-west of Manor House) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
