Fire stopping in North End
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a job in North End, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Make sure the joints can be reached
- Tell us what induction or permit system the site runs
- Have the specification and drawings to hand

Fire stopping for commercial buildings in North End
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is head-of-wall gaps with no fire seal and old intumescent sealant that has split away. Most enquiries from North End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Surface by surface
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Service penetrations in North End buildings
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
Workshops and IT rooms at colleges like London South East Colleges: Bexley (1.3 miles north-west of North End) are re-serviced often, leaving penetrations to seal. For a hospital such as Erith and District Hospital, 1.4 miles north-west of North End, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
North End is about 2 miles north-west of Dartford, in Greater London. Looking for fire stopping in North End? We can help. Our Greater London coverage takes in 764 places, large and small. Our London page has more on work in that area (13 miles or so).
If you need fire stopping in DA8, DA1 and DA7, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Oak Road, Elm Road and Moat Lane or close by, send details and we will quote for service penetrations.

A short drive away, we cover London (13 miles west), City of Westminster (15 miles west), Marylebone (15 miles west), St Pancras (14 miles west), Shoreditch (12 miles west) and Walthamstow (13 miles north-west).

Do you need fire stopping in North End?
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Typical triggers for a call:
- Unsealed joints where partitions meet the slab
- Service penetrations left open after M&E works
- Fire stopping installed outside its tested range
- Openings found when ceilings come down for a refit
For a unit at a centre such as Tower Retail Park, 1.2 miles to the south-west of North End, penetration seals are worth checking after each shop fit.
What to look for in a quote
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- The named product and why it was chosen
Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief every trade that openings they make must be sealed
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
- Ask which product is in place before decorating
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
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.
FAQs: North End
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in North End?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you work on fire-rated sealing in hotels in North End?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photos or drawings if you have them.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Fire doors, dampers or other fire safety equipment
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Surfaces we seal
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
Cost factors for service penetrations
To price the job, we consider:
- Working within restricted access windows
- The size and state of each joint
- Travel to remote or island sites
- Removal of failed or old sealant
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
What we need to price the job
However big the job, the same details help:
- Access details, including height
- Asbestos survey details if the building is older
- Any dates the work must fit around
- Where the site is, with the postcode
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email the details over if you’d rather talk the job through.
