Fire stopping in North Lee
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near North Lee may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance

Advice
Fire stopping in North Lee
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. Most enquiries involve improvised or mixed-product fire seals and unsealed joints where partitions meet the slab, on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations. For commercial sealant work in North Lee, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a smaller site near North Lee, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Fire stopping in North Lee: the local picture
Two care or nursing homes sit less than 2 miles from North Lee. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified. In England, Approved Document B covers fire stopping of 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. We install whatever has been specified, to the product’s tested detail.
Large healthcare estates like Stoke Mandeville Hospital (1.7 miles north of North Lee) change their services often, so penetration seals are worth checking after M&E work. Tenant changes at centres like Friars Square (to the north of North Lee) often mean new services through walls between units.

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Approving the work on behalf of building control
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap

Questions we’re asked in North Lee
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in North Lee?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is a smaller place like North Lee outside your area?
No. Places such as North Lee are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can the building stay open while you work?
Normally, yes. Phased work can be planned so areas stay in use.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Cost factors for service penetrations
A fixed quote reflects the actual work. It takes account of:
- Any access equipment needed
- Distance, for remote addresses
- The total length or number of joints
- Phasing around occupants
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- Any specification or named product
For a fixed quote, ring 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask which product is in place before decorating
- Arrange inspection before areas are covered up
- Agree the fire-stopping specification before services go in
- Foam or ordinary sealant is never a fire-seal repair
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.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Signs you need fire stopping in North Lee
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Any of the following is a good reason to get the joints checked over:
- Open linear gaps along the top of fire-resisting walls
- Service penetrations left open after M&E works
- Fire stopping installed outside its tested range
- Old intumescent sealant that has split away
Colleges such as Buckinghamshire College Group, 3 miles to the north of North Lee, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
- Health and safety accreditation such as CHAS
