What happens if it’s left?
Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. Getting scaffold, permits or access booked in Totteridge takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

About our fire stopping in Totteridge
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with fire-stopping items raised at inspection or handover and unsealed openings around new pipes and cables, we can help, whatever the surface. Most enquiries from Totteridge start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. In Totteridge, 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.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work
- Have the specification and drawings to hand

Your questions answered
Do you take on work at healthcare sites like Barnet Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you cover business parks and estates near Totteridge, such as Hadley Manor Trading Estate?
Yes. Our area takes in Totteridge and its surroundings, with estates and business parks such as Hadley Manor Trading Estate included. Send details of the unit and the work through our quote form for a quick quote.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
Do you design or specify fire stopping?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is BS 476 being phased out?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
Looking after the joints
For the best life from the joints:
- Get seals inspected before ceilings and boxing close
- Record which product was used where
- Foam or ordinary sealant is never a fire-seal repair
- Settle who seals which penetrations at the start of a project
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.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
- Construction that lacks the fire resistance the seal relies on
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
Fire stopping in Totteridge: the local picture
With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Colleges such as Oak Hill College, 2.3 miles east of Totteridge, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Shop fits in centres such as Spires Shopping Centre (to the north of Totteridge) can bring new services through fire-resisting walls between units, which then need the specified seal. Industrial units on estates such as Hadley Manor Trading Estate, 1.3 miles north of Totteridge, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
