About our fire stopping in Mountnessing
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 cable penetrations, and what we are called in for most is non-fire-rated filler around services and unsealed penetrations discovered above suspended ceilings. For commercial sealant work in Mountnessing, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Mountnessing is usually planned around one visit, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Mountnessing: questions and answers
Is Mountnessing off your patch?
Not at all. Mountnessing is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do you take on work at healthcare sites like Brentwood Community Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you design or specify fire stopping?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it.
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.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Surface by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Approving the work on behalf of building control
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers

Mountnessing lies roughly 22 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

What we install is set by the specification, and it goes in to the tested detail.

What else we do in Mountnessing
Why it’s worth doing now in Mountnessing
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Around Mountnessing, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. If others near Mountnessing need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Getting the site ready
- Move anything stored against the joints
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
Quotes
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email drawings and photos.
Advice
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Ask which product is in place before decorating
- Get seals inspected before ceilings and boxing close
- Record which product was used where
- Make fire stopping part of every scope that crosses a fire-resisting wall
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
