What affects the price in East Dulwich
To price the job, we consider:
- How much there is to seal
- Removal of failed or old sealant
- Joint width, depth and condition
- Distance, for remote addresses
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- What the building is and how it’s used
- The site address and postcode
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Fire stopping in East Dulwich, done properly
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. If you’re dealing with improvised or mixed-product fire seals and expanding foam used as fire stopping, we can put it right, whatever the surface. For commercial sealant work in East Dulwich, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Get seals inspected before ceilings and boxing close
- Treat an open penetration as a priority repair
- Ask the designer to confirm details early on refits
- Look above ceilings when tiles are lifted for other jobs
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
Fire stopping around East Dulwich: how the place shapes the job
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits. 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. Either way, we install the specified product to its tested detail.
In a retail centre such as Cantium Retail Park (1.7 miles north-east of East Dulwich), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Workshops and IT rooms at colleges like William Booth College (less than half a mile north-west of East Dulwich) are re-serviced often, leaving penetrations to seal. On estates like Goose Green Trading Estate, 0.5 miles east of East Dulwich, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Why deal with it now?
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. In East Dulwich, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations

Questions we’re asked in East Dulwich
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Do you take on work at healthcare sites like Maudsley Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.
What do you charge?
Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email a schedule or drawings with a description of the work.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance.
