Fire-rated sealant in Headley, Surrey

Problem with your fire-stopping gaps in Headley? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

  • Joints picked up in a fire-stopping survey
  • New service routes left unsealed after building work
  • Open gaps behind door architraves

Need fire rated sealant in Headley?

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed 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 doesn’t work out, we can still put it right.

Fire rated sealant in Headley, done properly

We can work through a building room by room or floor by floor. That record is useful for your files and for whoever looks at the building next. If you have new service routes left unsealed after building work and old fire sealant that has split or come away, we can help, on linear gaps, service penetrations and door frames alike.

Somewhere as small as Headley, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Fire rated sealant in Headley: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 look after a church, hall or community building such as Church of St Mary the Virgin, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as St Andrew's Catholic School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How we quote for fire rated sealant

We quote each job individually. This is what makes a difference:

  • How easy the joints are to reach
  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Helping us quote

Photos help, but a description is a good start. Please mention:

  • How we’d reach the joints
  • The type of property
  • Where the job is, and your postcode
  • Photos by email, if that’s easy

If you’re in Headley and need fire rated sealant, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before we start.

When it is not the sealant

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

  • Walls or floors that weren’t built to resist fire
  • Problems with the door itself rather than the gap around the frame
  • Issuing a fire rating or certificate for a building

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

Where we work in Headley

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

How the job changes by surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

When to call us in Headley

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

The most common problems we see are:

  • Unsealed gaps around fire door frames
  • Linear gaps at the head of walls
  • Ordinary sealant used where a fire-rated product was needed
  • Fire stopping disturbed by later work

Letting a property close to Tadworth station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

10 questions to ask before you book

How it works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. Somewhere as small as Headley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Keep children and pets away from the work area
  • Tell us about access, such as stairs, a lift or high-level joints
  • Try not to wet indoor joints just before the visit

Advice

Headley questions

I let a flat near Tadworth station. Can you help?

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

Is Headley in your area for fire rated sealant?

Yes, Headley 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 tell us what needs doing.

Do you seal gaps around fire door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door, its seals and closer are for a door specialist.

How long does the job take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. Your quote will say how long we expect yours to take.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.

Is it OK to seal over old sealant?

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