Fire stopping around West Green: points for this area
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. There are three care or nursing homes within about 2 miles of West Green. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.
At a healthcare site like St Ann's Hospital, under half a mile to the south of West Green, new services through compartment walls are a constant, and each needs the specified seal. For a hotel such as Haringey Hotel, which lies south-west of West Green, penetration seals are worth checking after any refit or services upgrade. Campus buildings at universities such as American University in London, 2.1 miles south-west of West Green, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Fire stopping for commercial buildings in West Green
Facilities managers in West Green often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve service penetrations left open after M&E works and head-of-wall gaps with no fire seal, on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. Most enquiries from West Green 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.
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. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Location, for remote and island sites
- Access and working height
- How much there is to seal
- Joint width, depth and condition
A quote for service penetrations depends on quantities, condition and access. Call for a quote.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- Asbestos survey details if the building is older
- When you need the work done
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email us.
Questions about West Green
Can work at a site such as American University in London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you seal penetrations in a hotel in West Green after a refit?
Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
What we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations
Leave it or put it right?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Looking after the joints
After handover, these steps help:
- Report damaged or disturbed seals as soon as they’re spotted
- Keep product data and details in the fire safety file
- Have penetrations checked while they can still be seen
- Keep general-purpose fillers away from compartment walls
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Send your site hours and access windows
- Tell staff and tenants when we will be in
- Tell us which areas need to stay in use

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
