Fire stopping in Ham, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, phone 01277 525 020 or send photos by email with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and unsealed penetrations discovered above suspended ceilings. One point of contact handles commercial sealant work in Ham from the first photos to the final walk-round, 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 is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What happens if it’s left?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Openings that need collars, wraps, batts or boards rather than sealant
- Approving the work on behalf of building control
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Fire-rated sealing for Ham buildings
There are a good number of hotels within about 2 miles of Ham. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Residences at universities like St Mary's University (1 mile west of Ham) have compartment walls that must be resealed whenever services change. Tenant changes at centres like Bentall Centre (to the south of Ham) often mean new services through walls between units. Hospital estates such as Cassel Hospital (less than half a mile south of Ham) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Ham is about 1 mile south-east of Twickenham, in Greater London. Across the TW10 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, Ham among them. There’s a separate page for London, roughly 10 miles from Ham.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Send your site hours and access windows
- Make sure the joints can be reached
- Tell staff and tenants when we will be in

Questions we’re asked in Ham
Does your area include sites such as St. George's Industrial Estate, near Ham?
Yes, sites like St. George's Industrial Estate are within our area, along with the rest of Ham. Send details of the unit and the work through our quote form for a quick quote.
Can you seal penetrations in a hotel in Ham after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
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.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months on every job.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Maintenance after handover
To get the most from the new sealant:
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
- Treat an open penetration as a priority repair
- Ask the designer to confirm details early on refits
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
What the job involves on each surface
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter.
