Fire rated sealant in Shorwell

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. Common call-outs are for fire seals that have cracked with movement and open holes round services passing through fire walls, on flats & HMOs, pipe & cable gaps and linear gaps.

Work in a small place like Shorwell is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

There’s a 12-month guarantee on every job.

Commercial buildings in Shorwell

If you run a hotel, guest house or holiday let in a coastal place like Shorwell, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.

In and around Shorwell, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Questions from Shorwell

Is there a guarantee on fire rated sealant in Shorwell?

All our work, in Shorwell and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Can you do fire rated sealant in Shorwell?

Yes, Shorwell is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

Can tenants book the work?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done.

Do you do fire sealant around door frames?

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

What should I tell you?

Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.

How do I get a quote for fire rated sealant in Shorwell?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Do you need fire rated sealant in Shorwell?

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Common reasons people contact us include:

  • Ordinary sealant used where a fire-rated product was needed
  • Unsealed gaps around fire door frames
  • Joints picked up in a fire-stopping survey
  • Open joints along the top of partitions

Community buildings like St. Peter's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

How to choose a mastic man

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around Shorwell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Why Shorwell customers choose us

  • Full insurance on every job
  • Homes, businesses and hotels
  • Any old sealant cut out fully, not covered over

What we do, step by step

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Shorwell needs a little journey planning: 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 begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used.

How to prepare

  • Let us know about parking restrictions
  • On commercial sites, let us know about site rules
  • Let us know if you’ve seen damp or leaks

Surface by surface

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for each gap size.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.

What affects the quote in Shorwell

The quote reflects the job in front of us. We take into account:

  • The old material and how stubborn it is
  • The type of sealant required
  • The number and length of the joints
  • Mould in or behind the old joints

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What to tell us for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • Access, such as stairs, a lift or height
  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, phone 0345 464 0079 or drop us an email.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we cannot put right

We will not take on work that won’t last, so here’s what sealant cannot put right:

  • A wall that is not a fire-resisting element to begin with
  • Sign-off of the building, which sits with building control or your assessor
  • Openings too large for sealant, which need batts, boards or another system

If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
