Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle fire stopping in Bromley-by-Bow
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with old intumescent sealant that has split away and snag lists that include open service penetrations, we can put it right, whatever the surface. A single leaking joint is often how a building in Bromley-by-Bow first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Signs you need fire stopping in Bromley-by-Bow
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.
Common reasons buildings call us in:
- Fire sealant pulled out of the opening
- Openings left by services added after handover
- Builders’ foam or ordinary silicone in compartment walls
- Penetration schedules that need working through
Tenant changes at parks like Bow Enterprise Park (less than half a mile south of Bromley-by-Bow) bring new data and services, and openings through fire-resisting walls need the specified seal.

Bromley-by-Bow: questions and answers
Is hospital work, at somewhere like Mile End Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can you seal penetrations in a hotel in Bromley-by-Bow after a refit?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
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.
Service penetrations in Bromley-by-Bow buildings
The 2 miles around Bromley-by-Bow include 10 care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Plenty of hotels sit less than 2 miles from Bromley-by-Bow. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Wherever services are added at a hospital such as Mile End Hospital (1.1 miles west of Bromley-by-Bow) the compartment line has to be made good with the specified product. Residences at universities like University of Cumbria in London, 1 mile to the south of Bromley-by-Bow, have compartment walls that must be resealed whenever services change.

Doing it in-house
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Backing rod, priming and other preparation
- How much existing material needs removing
- Working within restricted access windows
- The total length or number of joints
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- The site address and postcode
- Whether the building will be occupied during the work
- Clear photographs of the problem areas
- Any specification or named product
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email drawings and photos.
How the job changes by surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Before we start on site
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached
