Fire stopping for commercial buildings in Teddington
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. If you are dealing with service penetrations left open after M&E works and old intumescent sealant that has split away, we can put it right, on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Teddington, that means joint design, primers and backing rod as standard.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
Building owners and contractors get the same cover: 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.

Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Have penetrations checked while they can still be seen
- Keep general-purpose fillers away from compartment walls
- Check with the data sheet before painting over fire sealant
- Agree the fire-stopping specification before services go in
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.

Why act early in Teddington
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. In Teddington, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

FAQs: Teddington
Could you schedule work at a campus like St Mary's University for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you cover business parks and estates near Teddington, such as Newmans Shipyard & Business Park?
Yes. We cover Teddington and the area around it, including industrial estates, business parks and retail parks such as Newmans Shipyard & Business Park. A few photographs and the unit address let us price the work.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Is Teddington in your area?
Yes. Teddington falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email us.
Will fire-rated sealant work on every penetration?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Fire doors, dampers or other fire safety equipment
- Plastic pipes whose detail calls for a collar or wrap
- Gaps in walls that were never built as compartment walls
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- 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
Where services cross fire walls in Teddington
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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
At a university such as St Mary's University (0.7 miles north of Teddington), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a building at a site such as Newmans Shipyard & Business Park, 0.9 miles to the north of Teddington, a check of penetration seals after each fit-out is good practice.
Teddington is about 5 miles west of Wimbledon, in Greater London. Anywhere in TW11, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 764 places in Greater London. Sites around London have their own page, roughly 11 miles from Teddington.

Local landmarks in Teddington
Around Teddington, our work takes us to commercial buildings near Bushy Park, Turing House School and Newland House School and the streets around them.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. 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.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Send your site hours and access windows
- Have the specification and drawings to hand
- Flag any permit to work we will need

Signs you need fire stopping in Teddington
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access typically bring them to light.
It’s worth sending us details if you spot any of the following:
- Head-of-wall gaps with no fire seal
- Unsealed openings around new pipes and cables
- Seals disturbed by maintenance and left open
- Improvised or mixed-product fire seals
At a college such as Kingston College Creative Industries Centre (1.6 miles south-east of Teddington), checking penetration seals after summer M&E works is good practice.
