Fire rated sealant for homes and businesses in Fyfield

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on door frames, service penetrations and linear gaps, and people most often call us about open gaps behind door architraves and new service routes left unsealed after building work.

For holiday lets, converted business premises or a community building near Fyfield, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • The type of sealant required
  • How easy the joints are to reach
  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear quote before work begins.

Helping us quote

When you call or email, these details help:

  • Whether it has been sealed before
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved
  • Photos by email, if that is easy

We don’t publish a price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.

DIY versus a professional finish

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Different surfaces, different methods

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we’re sealing.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Check whether a sealant can be painted before decorating over it
  • Store the list of sealed gaps with your building paperwork

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed 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.

Fyfield: your questions answered

Is fire rated sealant in Fyfield guaranteed?

Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Is Fyfield in your area for fire rated sealant?

Yes, Fyfield is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

What does intumescent mean?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.

Where do you work from?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Can you fill the gap behind a fire door frame?

Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.

How long does fire rated sealant take?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will say how long yours will take.

Can tenants book the work?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Will it make a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

The process

Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Fyfield needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  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

  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions

How to get a quote

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

What we are called out for in Fyfield

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

The most common problems we see are:

  • Joints picked up in a fire-stopping survey
  • Fire seals that have cracked with movement
  • Open gaps behind door architraves
  • New service routes left unsealed after building work

For buildings such as Church of St Nicholas, older buildings that have had new heating or wiring often have service gaps worth checking.

Before you book anyone

  • Whether they’re fully insured
  • Which colour the sealant will be
  • What product goes in the joint
  • Whether they seal over old material or remove it

Our hiring checklist

Why it’s worth doing now in Fyfield

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. In a small place like Fyfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
