Fire rated sealant near Sway

Fire rated sealant in Sway

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you are dealing with ordinary sealant used where a fire-rated product was needed and gaps flagged on a fire risk assessment, we can put it right.

In a smaller place like Sway, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Different surfaces, different methods

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length so there are no open sections left.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Your questions about fire rated sealant in Sway

Will you come out to Sway?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Can new sealant go over the old?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings. The product needed can limit the range.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame, and we will mention anything we notice about the door.

Do you carry out fire risk assessments?

No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.

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 the preparation. Your quote will say how long we expect yours to take.

Fire rated sealant around Sway

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

Letting a property close to Sway station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as St Luke's Church, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like St Luke's Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Honest limits

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

  • Walls or floors that weren’t built to resist fire
  • Fire risk assessments, which need a qualified assessor
  • Fire doors that need new seals, closers or hardware

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Surfaces we seal

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

What we do, step by step

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Parking around Sway is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  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 and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • Mention if the joints have been sealed before
  • Clear items away from the joints we are working on
  • For business premises, tell us about site rules or sign-in

Advice

Quotes for fire rated sealant in Sway

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Working hours on commercial sites
  • Whether the work is at height
  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What we need to know

To help us quote quickly, let us know:

  • Where the job is, and your postcode
  • What’s wrong with the joints now
  • The rough size of the job
  • How we’d reach the joints

We quote each job on its own. Simply ring 0345 464 0079 or email us and describe the job and send pictures if you have them.

Landlord and commercial work in Sway

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

Why it’s worth doing now in Sway

Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In an older home around Sway, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
