Fire rated sealant for homes and businesses in Southfields

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. If you are dealing with old fire sealant that has split or come away and unsealed gaps where pipes and cables go through a wall, we can put it right.

In a village or hamlet like Southfields, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You get a 12-month guarantee, the same in Southfields as everywhere else we work.

Southfields: your questions answered

Do you work for landlords with property near Stanford-Le-Hope station?

Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Is Southfields in your area for fire rated sealant?

Yes, Southfields is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Can you match the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

What’s the difference between intumescent and fire-rated sealant?

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.

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.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.

Can new sealant go over the old?

No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

What the job involves on each surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length leaving no stretch unsealed.

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.

When something else is needed

To be straight with you, some problems need a different trade:

  • A wall that isn’t a fire-resisting element to begin with
  • Large holes that need a different fire-stopping system
  • Certifying a building or signing off its fire safety

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What we seal

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

How it works

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. For a village or hamlet like Southfields, the journey is planned in advance: let us know about lanes, gates and parking. 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. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we’re working on
  • Tell us about any water getting in

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Access and height
  • The size of the job
  • Any mould that needs treating
  • Working hours on commercial sites

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Helping us quote

To make quoting easier, please include:

  • What’s wrong with the joints now
  • Any previous sealing or DIY work
  • Photos by email, if that’s easy
  • The type of property

Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand.

How to look after the new joints

A little care helps the new joints last. Our advice:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Look in service cupboards and ceiling voids from time to time
  • File the fire-stopping record where your assessor can find it
  • Take photos of fire stopping before ceilings or boxing go back

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Fire rated sealant around Southfields

If you run a hotel, guest house or holiday let in a coastal place like Southfields, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 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 Stanford-Le-Hope station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as St Giles & All Saints Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Orsett Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
