Fire stopping in Higham Hill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Send any specification or drawings in advance
- Agree which areas must stay open
- Share the asbestos register for older buildings

Advice
About our fire stopping in Higham Hill
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call the office on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are old intumescent sealant that has split away and service penetrations left open after M&E works. Looking for mastic applicators who cover Higham Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Foam or ordinary sealant is never a fire-seal repair
- Flag new cables with no seal around them
- Check with the data sheet before painting over fire sealant
- Look above ceilings when tiles are lifted for other jobs
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
What affects the price in Higham Hill
A fixed quote reflects the actual work. It allows for:
- The size and state of each joint
- Location, for remote and island sites
- Any access equipment needed
- Removal of failed or old sealant
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
What we need to price the job
However big the job, the same details help:
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- Specification clauses that apply
- What the building is and how it’s used
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email us if you’d rather talk the job through.
How the job changes by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
When to call us in Higham Hill
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
It’s worth sending us details if you spot any of the following:
- Improvised or mixed-product fire seals
- Fire-rated sealant that has cracked or shrunk back
- Non-fire-rated filler around services
- Openings found when ceilings come down for a refit
Tenant changes at parks like Uplands Business Park, 0.5 miles to the south-west of Higham Hill, bring new data and services, and openings through fire-resisting walls need the specified seal.

Fire stopping around Higham Hill: points for this area
In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. The area within 2 miles of Higham Hill holds several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Workshops and IT rooms at colleges like Hope Business & Technology College, 0.6 miles south of Higham Hill, are re-serviced often, leaving penetrations to seal. At a university such as University of Portsmouth Walthamstow Campus, 1.4 miles south-east of Higham Hill, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Higham Hill is about 1 mile north-west of Walthamstow, in Greater London. Anywhere in E17, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Higham Hill: questions and answers
Can you work on a hospital site such as North Middlesex University Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work in a London building with booked loading and goods-lift slots?
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. The ULEZ covers the whole of Greater London, which we allow for
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How do we ask for a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed and agree any further records when we quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Gaps in walls that were never built as compartment walls
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.
What we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
- Joints between fire-resisting walls and floors
