Fire rated sealant in Plummers Plain

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We work on pipe & cable gaps, flats & HMOs and plasterboard & masonry, and common reasons people get in touch are open joints along the top of partitions and seals cut through by electricians, plumbers or data installers.

For a small place like Plummers Plain, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Plummers Plain: your questions answered

Is Plummers Plain within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

I let a flat near Faygate station. Can you help?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Can I choose the sealant colour?

Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

Is the work guaranteed?

Yes. Every job comes with a one-year guarantee.

Can you do several jobs on one visit?

Yes. Just list everything you need.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Will the old sealant be removed?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

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

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Fire rated sealant around Plummers Plain

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as St Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Newells Preparatory School, fire-stopping around service openings should be restored whenever new services go in.

When it is not the sealant

To be straight with you, some problems need a different trade:

  • Problems with the door itself rather than the gap around the frame
  • Fire risk assessments, which need a qualified assessor
  • Big openings where sealant alone isn’t the tested solution

If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

Where we work in Plummers Plain

  • Plasterboard & masonry
  • Flats & HMOs
  • Service penetrations
  • Door frames
  • Linear gaps
  • Pipe & cable gaps

What we’re called out for in Plummers Plain

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Common reasons people contact us are:

  • Unsealed gaps around fire door frames
  • Joints picked up in a fire-stopping survey
  • Gaps where walls meet ceilings or slabs
  • Ordinary sealant used where a fire-rated product was needed

If you let a flat or house near Faygate station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before booking

  • Whether VAT is included
  • Whether they’re fully insured
  • What the cure time is
  • Whether you can choose the colour

10 questions to ask before you book

Surface by surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Keep pictures of seals that will be hidden
  • Keep the record of products and locations with your fire safety documents
  • Check whether a sealant can be painted before decorating over it

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.

What affects the cost of fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • The size of the job

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • The rough size of the job
  • The problem you’ve noticed
  • If it’s domestic, commercial or a hotel
  • Pictures of the joints, sent by email

For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. Somewhere as small as Plummers Plain, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height
  • Let us know about parking restrictions
