On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. In Forest Gate, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Make sure the joints can be reached

Advice
Fire stopping in Forest Gate
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and openings found when ceilings come down for a refit. Whoever orders the work in Forest Gate, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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’ll hear it from us.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we will arrange a return visit.

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Building owners, agents and FMs in Forest Gate
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Surface by surface
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 along with any permits your site needs.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. In Forest Gate, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Penetration seals near Forest Gate
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. Forest Gate has 37 care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
On a site such as Acacia Business Centre (1 mile north-west of Forest Gate), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Theatres, wards and plant rooms at sites like Newham University Hospital (to the south of Forest Gate) all have compartment walls crossed by services.

Questions about Forest Gate
Would you work within a site like Newham University Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Could you schedule work at a campus like University of East London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you work in Forest Gate?
Yes. We cover Forest Gate, and the simplest way to start is to speak to us on 01277 525 020 or email drawings and photos.
Does the weather affect the work?
It can, for external work. 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.
Common problems we fix in Forest Gate
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
Things that normally lead to an enquiry:
- Fire-rated sealant that has cracked or shrunk back
- Seals that don’t match their tested detail
- Service penetrations left open after M&E works
- Damaged fire seals in risers and voids
Shop fits in centres such as Stratford Centre, 1.3 miles to the south-west of Forest Gate, can bring new services through fire-resisting walls between units, which then need the specified seal.
