Fire stopping for Mildmay sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Do you need fire stopping in Mildmay?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
These are often picked up first by site or facilities staff:
- Fire-rated sealant that has cracked or shrunk back
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed penetrations discovered above suspended ceilings
- Open linear gaps along the top of fire-resisting walls
At a university such as University of Wales Trinity Saint David London, 1.1 miles south of Mildmay, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Before you book anyone
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Fire stopping in Mildmay, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have improvised or mixed-product fire seals and damaged fire seals in risers and voids, we can put it right, on service gaps in risers, joints between fire-resisting walls and floors and cable penetrations alike. Facilities teams, main contractors and managing agents in Mildmay tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Quoting for work in Mildmay
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Quantities, in metres or numbers
- Phasing around occupants
- The product specified
- Induction, permit and paperwork requirements
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Before you send an enquiry
However big the job, the same details help:
- Specification clauses that apply
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Building owners, agents and FMs in Mildmay
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Service penetrations in Mildmay buildings
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. 11 care or nursing homes sit less than 2 miles from Mildmay. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
Colleges such as City & Islington College (1.3 miles north-west of Mildmay) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a unit at a centre such as Arena Shopping Park, 2 miles to the north of Mildmay, penetration seals are worth checking after each shop fit.
Mildmay is about 1 mile north of Hoxton, in Greater London. Our applicators travel to Mildmay for work on service penetrations, handled exactly as we handle every other area. Mildmay is one of 764 places we cover in Greater London for service penetrations.
Anyone looking for fire stopping in N1, N16 and E8 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on Dove Road, Essex Road and Burma Road. With the A1199 nearby, Mildmay is easy to get to with materials and equipment. If your building is just outside Mildmay, we cover Newington Green (1 mile north), De Beauvoir Town (1 mile south), Canonbury (1 mile south-west), Kingsland (1 mile south-east) and Highbury (1 mile west). A short drive away, we cover London (3 miles south), City of Westminster (4 miles south-west), Marylebone (3 miles south-west), Kensington (6 miles south-west), Walthamstow (4 miles north-east) and Hampstead (4 miles west).
Local landmarks in Mildmay
We work on buildings around City of London Academy Highbury Grove, Highbury Fields and Army and Navy pub, among other places. There’s a railway station in Mildmay itself: Dalston Kingsland station. Well-known places in the area include Clowns Gallery-Museum (0.6 miles south-east) and Hackney Walk (1.5 miles east). Green spaces nearby include Gillespie Park and Ludgate Hill.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. All of Greater London is in the ULEZ, and kerbside space in Mildmay can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.
Advice
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Leave fire sealant to cure fully before covering it
- Record which product was used where
- Include service cupboards in routine inspections
- Settle who seals which penetrations at the start of a project
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think.

Questions we’re asked in Mildmay
Can work at a site such as University of Wales Trinity Saint David London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you take on a job at a hospital such as Mildmay Mission Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you cover Mildmay?
Yes. Mildmay is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. To discuss a job, ring 01277 525 020 or email drawings and photos.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
