Fire rated sealant in Leeds

Looking after it afterwards

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

  • Make resealing part of every contractor’s brief
  • Include fire stopping when you schedule refits
  • Store the list of sealed gaps with your building paperwork
  • Photograph sealed gaps before they’re covered up

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

About our fire rated sealant in Leeds

We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on pipe & cable gaps, flats & HMOs and door frames, and common reasons people get in touch are open gaps behind door architraves and fire seals that have cracked with movement.

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

Our work is backed for twelve months, in Leeds and everywhere else we cover.

What happens on the day

We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. For a village or hamlet like Leeds, the journey is planned in advance: 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 go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  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.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Clear items away from the joints we are working on
  • Tell us about access, such as stairs, a lift or high-level joints

What affects the cost of fire rated sealant

We don’t publish a price list. What we look at:

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

When you contact us, it’s useful to know:

  • Whether it’s a home or a business

  • The address or postcode of the job
  • Any previous sealing or DIY work

Why act early in Leeds

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Older cottages and farmhouses around Leeds can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

Fire rated sealant in Leeds: local notes

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.

If you look after a building such as Leeds and Broomfield Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Hollingbourne station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as St Nicholas's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Common questions in Leeds

Do you cover Leeds for fire rated sealant?

Yes. We work across London and the South East, and Leeds is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.

Can you help a landlord with a rental near Hollingbourne station?

What fire rating will the seal have?

We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

How long does the job take?

Most jobs take 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.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Where do you work from?

Mr Mastic is based in Crawley. We cover Leeds and the rest of Kent.

Will we have a record of what was sealed?

Yes. You get a list of where we worked and what we used for your files.

Different surfaces, different methods

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
