Your questions answered
Is North End too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as Broomfield Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you have third-party installer accreditation for fire stopping?
No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so check your contract first. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you fire stop behind the services contractors?
Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see, and we reseal them to the specified detail.
Fire stopping for commercial buildings in North End
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and the failures we’re asked to look at most are penetration schedules that need working through and improvised or mixed-product fire seals. Looking for mastic applicators who cover North End? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Smaller places such as North End still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Converted and older buildings near places like North End tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Agree the fire-stopping specification before services go in
- Check with the data sheet before painting over fire sealant
- Get seals inspected before ceilings and boxing close
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Compartments and services around North End
Central London is about 32 miles from North End. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Schools such as The Flitch Green Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. On estates like Martels Industrial Estate, 1.6 miles to the north-west of North End, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

When to call us in North End
