Fire stopping in Tower Hill, done properly
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Tower Hill. If you are dealing with hidden openings found during inspections and seals that don’t match their tested detail, we can put it right, on linear gaps at wall heads, service gaps in risers and cable penetrations alike. Looking for mastic applicators who cover Tower Hill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a London area such as Tower Hill, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
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.

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Cost factors for service penetrations

- Working within restricted access windows
- Distance, for remote addresses
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
There’s no price list, since every building and every scope is different. Call for a quote.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or send photos by email.
Our process
The first thing on site is a walk round with your contact, 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. Most London premises stay occupied while we are on site, 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.
- Openings are measured and grouped by detail.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed

Advice
Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

After the work
For the best life from the joints:
- Don’t let anyone top up a fire seal with the wrong product
- Keep product data and details in the fire safety file
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.
Compartments and services around Tower Hill
A 2-mile radius around Tower Hill takes in plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
Tenant changes at centres like Southernwood Retail Park (1.4 miles south of Tower Hill) often mean new services through walls between units. For a hospital such as London Bridge Hospital, under half a mile south-west of Tower Hill, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Workshops and IT rooms at colleges like London College of Marketing and Technology, 0.6 miles to the north-east of Tower Hill, are re-serviced often, leaving penetrations to seal.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Common questions from Tower Hill clients
Do you take on jobs in Tower Hill where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Do you seal service penetrations in hotels around Tower Hill?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How long will the new sealant last?
Nobody can honestly give a figure in years, 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.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
