Fire stopping around Waltham Forest: points for this area
A 2-mile radius around Waltham Forest takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. 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. Our part stays the same: the specified product, installed to its tested detail.
At a college such as New City College, which lies east of Waltham Forest, checking penetration seals after summer M&E works is good practice. Hospital estates such as The Holly Private Hospital (to the south-east of Waltham Forest) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Fire stopping in Waltham Forest
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you have unsealed openings around new pipes and cables and fire-rated sealant that has cracked or shrunk back, we can put it right, on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows alike. One point of contact handles commercial sealant work in Waltham Forest from the first photos to the final walk-round, for single jobs and planned programmes alike.
In a London area such as Waltham Forest, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Every job we finish is backed by a 12-month workmanship guarantee, in Waltham Forest as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Waltham Forest
Can you work on a hospital site such as The Holly Private Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Oakwood Hill Industrial Estate, near Waltham Forest, within your area?
Yes, sites like Oakwood Hill Industrial Estate are within our area, along with the rest of Waltham Forest. Send details of the unit and the work through our quote form for a quick quote.
Will fire-rated sealant work on every penetration?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, specified by your designer.
What do you charge?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email the details over with a description of the work.
How many days will you need on site?
It depends on the scope, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
What sets the cost
To price the job, we consider:
- How much existing material needs removing
- The site’s rules and procedures
- Quantities, in metres or numbers
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Access details, including height
- Any dates the work must fit around
- The asbestos register, for older buildings
- The site address and postcode
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, speak to us on 01277 525 020 or email drawings and photos.
What the job involves on each surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Openings that need collars, wraps, batts or boards rather than sealant
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
Signs you need fire stopping in Waltham Forest
Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.
Any of the following is a good reason to get the joints checked over:
- Builders’ foam or ordinary silicone in compartment walls
- Hidden openings found during inspections
- Penetration schedules that need working through
- Open linear gaps along the top of fire-resisting walls
For a unit at a centre such as Epping Forest Shopping Park, 2.8 miles east of Waltham Forest, penetration seals are worth checking after each shop fit.
