How we handle fire stopping in Putney
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you are dealing with unsealed openings around new pipes and cables and openings found when ceilings come down for a refit, we can help, on linear gaps at wall heads, cable penetrations and service gaps in risers alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Putney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
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’re clear about what is covered before work starts.

Fire stopping around Putney: how the place shapes the job
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. 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. Our part stays the same: the specified product, installed to its tested detail.
Colleges such as South Thames College Wandsworth Campus, 1.4 miles to the east of Putney, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Theatres, wards and plant rooms at sites like Royal Hospital for Neuro-Disability, 0.8 miles south-east of Putney, all have compartment walls crossed by services.
Putney is about 1 mile south-west of Fulham, in Greater London. Anywhere in SW15, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places. London is covered too, around 6 miles from Putney.
Commercial sites across SW15, SW19 and SW13 are covered for service penetrations. We cover commercial and managed buildings on Putney High Street, Upper Richmond Road and Spencer Walk and the roads nearby. Access to Putney is via the A3 and B306. Close to Putney, our area also takes in Roehampton (1 mile south-west), Barnes (1 mile north-west), Fulham (1 mile north-east), Mortlake (2 miles west) and Wimbledon Park (2 miles south). A short drive away, we cover London (6 miles north-east), City of Westminster (5 miles north-east), Marylebone (5 miles north-east), Kensington (3 miles north), St Pancras (6 miles north-east) and Shoreditch (8 miles north-east).

Building owners, agents and FMs in Putney
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Why act early in Putney
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, rather than turning into a full building survey and reseal. Getting scaffold, permits or access booked in Putney takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Do you need fire stopping in Putney?
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Common reasons buildings call us in:
- Unsealed penetrations discovered above suspended ceilings
- Head-of-wall gaps with no fire seal
- Fire seals cut back for extra cables and never reinstated
- Old intumescent sealant that has split away
In a retail centre such as Kew Retail Park, 2.7 miles to the north-west of Putney, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
What to look for in a quote

- Their approach to joint depth and backing
- The named product and why it was chosen
- Do they follow the manufacturer’s priming guidance?
Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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 so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Let us know about inductions and permits

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Walls or floors that aren’t fire-resisting to begin with
- Approving the work on behalf of building control
- Plastic pipes whose detail calls for a collar or wrap
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.
What we seal
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
Questions we are asked in Putney
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. Send the building rules and access times with your enquiry.
Can you seal around new services in a hotel near Putney?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we’ll set out a timescale with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How do we ask for a quote?
