Fire rated sealant for The Common homes and businesses

Should I try it myself first?

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 fails, we can still redo it.

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.

How we handle fire rated sealant in The Common

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. Common call-outs are for sealant items on a fire risk assessment action list and old fire sealant that has split or come away, on plasterboard & masonry, linear gaps and door frames.

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

All our work is covered by our 12-month guarantee, wherever you are in Essex.

Your questions about fire rated sealant in The Common

Is fire rated sealant in The Common guaranteed?

All our work, in The Common and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Is The Common within the area you cover?

Yes, The Common is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Where are you based?

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

Can you give us a record of the work?

Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.

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

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

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

Which products do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Landlord and commercial work in The Common

Letting agents and landlords in The Common can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Commercial buildings in The Common

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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Radwinter Church of England Voluntary Aided Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Mould in or behind the old joints
  • Access and height
  • The number and length of the joints
  • The old material and how stubborn it is

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Asking for a quote

Photos by email are helpful but not essential. Please mention:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • A few photos by email, if you can
  • Where the job is, and your postcode

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.

Do you need fire rated sealant in The Common?

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

Most people get in touch after spotting one of these:

  • Holes left by a change of layout
  • Old fire sealant that has split or come away
  • Seals cut through by electricians, plumbers or data installers
  • Open joints along the top of partitions

Community buildings like Church of St Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Before booking anyone

  • Is the old sealant removed completely?
  • How the colour is chosen
  • How long the guarantee is
  • What product goes in the joint

How to look after the new joints

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

  • Photograph sealed gaps before they’re covered up
  • Tell trades working in the building that fire seals must be put back
  • Check risers, ceiling voids and cupboards during building checks
  • Report cracked or damaged seals as soon as you notice them

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

How it works

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a small place like The Common, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  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. We record what was done and flag anything that needs a different system.

How to prepare

  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
  • Clear the area around the work

How the job changes by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
