Fire stopping for businesses in Three Mills
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
About our fire stopping in Three Mills
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. If you are dealing with seals that don’t match their tested detail and damaged fire seals in risers and voids, we can help. Most enquiries from Three Mills start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. In Three Mills, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- 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.
- 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 any areas we must not close
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Common questions from Three Mills clients
Do you take on jobs in Three Mills where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Is Crescent Court Business Centre, near Three Mills, within your area?
Yes. Estates, retail parks and business parks around Three Mills, Crescent Court Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
When is resealing likely to be due?
There isn’t a single answer, 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.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Fire stopping around Three Mills: points for this area
There are a good number of hotels within about 2 miles of Three Mills. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Residences at universities like Arden University Stratford Campus (1.1 miles north of Three Mills) have compartment walls that must be resealed whenever services change. For a unit at a centre such as Manor Road Retail Park (0.9 miles south-east of Three Mills), penetration seals are worth checking after each shop fit. For a building at a site such as Crescent Court Business Centre, less than half a mile south-east of Three Mills, a check of penetration seals after each fit-out is good practice.

Work for main contractors and building owners
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, with CSCS-carded applicators on site.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Three Mills can form part of a wider programme across Greater London.
Different surfaces, different methods
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.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
