What we are called out for in Slade Green
Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
It’s worth sending us details if you spot any of the following:
- Non-fire-rated filler around services
- Fire stopping installed outside its tested range
- Fire sealant pulled out of the opening
- Unsealed openings around new pipes and cables
In a retail centre such as Tower Retail Park, which lies south-west of Slade Green, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

Fire stopping in Slade Green
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 part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. We work on linear gaps at wall heads, cable penetrations and pipe penetrations, and what we’re called in for most is hidden openings found during inspections and fire sealant pulled out of the opening. A single leaking joint is often how a building in Slade Green first comes to us: 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.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Your questions answered
Can you seal penetrations in a hotel in Slade Green after a refit?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Do you take on jobs in Slade Green where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Different surfaces, different methods
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Planning a London job such as one in Slade Green starts with access. 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.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Tell staff and tenants when we’ll be in
- Make sure the joints can be reached
- Tell us which areas need to stay in use

Fire stopping around Slade Green: what changes locally
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Slade Green takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
For a hospital such as Erith and District Hospital, which lies north-west of Slade Green, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. At a university such as University of Greenwich, 3.6 miles to the south-east of Slade Green, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Slade Green is about 1 mile south-east of Erith, in Greater London. Across the DA8 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Sites around London have their own page, about 13 miles away.

Why act early in Slade Green
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
