Why it’s worth doing now in Parsons Green
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Getting scaffold, permits or access booked in Parsons Green takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

How we handle fire stopping in Parsons Green
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you have builders’ foam or ordinary silicone in compartment walls and head-of-wall gaps with no fire seal, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Parsons Green, preparation and product choice get the time they need.
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 will confirm with the quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Common problems we fix in Parsons Green
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
What tends to prompt an enquiry:
- Fire stopping installed outside its tested range
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
- Penetration schedules that need working through
For an estates team at a campus like BIMM University, less than half a mile to the north of Parsons Green, summer M&E works are usually followed by a round of penetration sealing.
What your quote should include
- Will CSCS-carded applicators be on site?
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
- Proof of insurance

What else we do in Parsons Green
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- 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
- Send any specification or drawings in advance
- Flag any permit to work we will need
- Send your site hours and access windows

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Writing the fire-stopping specification
- Fire risk assessments, a job for a competent assessor
- Construction that lacks the fire resistance the seal relies on
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
Your questions answered
Can you seal around new services in a hotel near Parsons Green?
Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you need to see the site first?
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.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Building owners, agents and FMs in Parsons Green
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Surface by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
Service penetrations in Parsons Green buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Hospital estates such as Chelsea and Westminster Hospital, 1.1 miles to the north-east of Parsons Green, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Tenant changes at parks like Hurlingham Business Park, 0.5 miles to the south of Parsons Green, bring new data and services, and openings through fire-resisting walls need the specified seal.
Parsons Green is about 2 miles south of Kensington, in Greater London. We send applicators to Parsons Green for service penetrations, handled exactly as we handle every other area. We work across 764 places in Greater London.
