Fire rated sealant in Beamond End, done properly

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with open joints along the top of partitions and door frames with gaps between frame and wall, on linear gaps, door frames and flats & HMOs.

Work in a small place like Beamond End is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

When to call us in Beamond End

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.

People usually contact us when they notice one of these:

  • Cracked or shrunken fire-rated sealant
  • Open joints along the top of partitions
  • Damaged fire sealant left by other trades
  • Ordinary sealant used where a fire-rated product was needed

If you look after a church, hall or community building such as Church of the Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building.

10 questions to ask before you book

Fire rated sealant around Beamond End

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

If you let a flat or house near Great Missenden station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Holmer Green Junior School, fire-stopping around service openings should be restored whenever new services go in.

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether old sealant or filler has to be cut out
  • The number and length of the joints
  • Whether the work is at height

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

FAQs for Beamond End

Is Beamond End within the area you cover?

Yes. Beamond End is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near Great Missenden station?

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Can you tell me how many minutes the seal will last?

We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.

What’s the difference between intumescent and fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

How long will you be here?

A typical job takes anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Do you take on fire stopping in schools and offices?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

The process

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. For a village or hamlet like Beamond End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your files.

How to prepare

  • Mention if the joints have been sealed before
  • Mention any sign-in or site rules at work premises
  • Keep children and pets away from the work area

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Tell trades working in the building that fire seals must be put back
  • Look in service cupboards and ceiling voids from time to time
  • File the fire-stopping record where your assessor can find it
  • Photograph sealed gaps before they’re covered up

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Leave it or put it right?

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Beamond End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Why us?

  • Anti-fungal sanitary silicone in wet areas

Surface by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Door frames

Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist and we’ll mention anything we notice.
