Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.
About our fire stopping in Church End
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and what we’re called in for most is seals that don’t match their tested detail and unsealed penetrations discovered above suspended ceilings. A specialist sealant contractor works differently from a general builder: in Church End, that means joint design, primers and backing rod as standard.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What we’re called out for in Church End
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.
Common reasons buildings call us in:
- Expanding foam used as fire stopping
- Service penetrations left open after M&E works
- Unsealed joints where partitions meet the slab
- Fire-rated sealant that has cracked or shrunk back
Wherever services are added at a hospital such as Finchley Memorial Hospital, 0.7 miles east of Church End, the compartment line has to be made good with the specified product.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire doors, dampers or other fire safety equipment
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.
Joints and surfaces we work on
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. 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. For a job in Church End, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Tell us what induction or permit system the site runs
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

Advice
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Where services cross fire walls in Church End
Seven care or nursing homes sit less than 2 miles from Church End. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Church End has a good number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Colleges such as St. Giles College, 2.8 miles south-east of Church End, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Tenant changes at centres like Grand Arcade, 1.1 miles north-east of Church End, often mean new services through walls between units.

FAQs: Church End
Can you work in a care home near Church End with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
Could you schedule work at a campus like Middlesex University for the vacation?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Will you sign off the seals for us?
No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you cover Church End?
Yes. We cover Church End, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
