What affects the cost of fire rated sealant

We do not publish a price list. What we look at:

  • Any working-time requirements on site
  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Helping us quote

When you call or email, it’s useful to know:

  • Whether it has been sealed before
  • Any access issues, like height or stairs
  • A few photos by email, if you can
  • What’s wrong with the joints now

About our fire rated sealant in Plastow Green

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We work on door frames, service penetrations and linear gaps, and people most often call us about fire seals that have cracked with movement and gaps where walls meet ceilings or slabs.

For a small place like Plastow Green, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

Big or small, it’s backed by our one-year guarantee in Plastow Green and across West Berkshire.

Workplaces and buildings in Plastow Green

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

If you let a flat or house near Thatcham station, any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as Cheam School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What we can’t put right

It helps to know what we can’t do too:

  • Problems with the door itself rather than the gap around the frame
  • A wall that is not a fire-resisting element to begin with
  • Deciding what fire stopping a building needs

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

Where we work in Plastow Green

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

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Do not paint over fire sealant until it has cured
  • Report cracked or damaged seals as soon as you notice them
  • Look in service cupboards and ceiling voids from time to time
  • Allow for resealing whenever new services are run

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Why it’s worth doing now in Plastow Green

Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Around Plastow Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Why book with us

  • Every job guaranteed for a year
  • Arbo and Everbuild products
  • Anti-fungal silicone where joints get wet
  • Any old sealant cut out fully, not covered over

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What we do, step by step

The work is kept neat and contained to the joints we’re treating. The job normally takes from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. For a village or hamlet like Plastow Green, 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. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Clear items away from the joints we are working on
  • Tell us about any previous sealing or DIY attempts

Advice

Plastow Green questions

Is Plastow Green in your area for fire rated sealant?

Yes. We work across London and the South East, and Plastow Green is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Is Plastow Green within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Will we have a record of what was sealed?

Yes. We record the locations we’ve sealed and the products used to keep with your fire safety documents.

Are you fully insured?

Yes. We’re fully insured.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

Do you guarantee your work?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Can I choose the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.

When to call us in Plastow Green

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Signs it’s time to call us include:

  • Fire seals that have cracked with movement
  • Door frames with gaps between frame and wall
  • Gaps around pipes and cables through fire-resisting walls
  • Open joints along the top of partitions

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