How the job changes by surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.

Fire rated sealant for homes and businesses in Horton

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We are often asked to deal with fire seals that have cracked with movement and joints picked up in a fire-stopping survey, across linear gaps, door frames and service penetrations.

Somewhere as small as Horton, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

There’s a 12-month guarantee on every job, whatever its size.

The process

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Horton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • On commercial sites, let us know about site rules
  • Tell us about any water getting in
  • Clear the area around the work

Advice

When to call us in Horton

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

The most common problems we see are:

  • Gaps around pipes and cables through fire-resisting walls
  • Old fire sealant that has split or come away
  • Joints picked up in a fire-stopping survey
  • New service routes left unsealed after building work

Schools such as Colnbrook Church of England Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Before you book anyone

  • Whether VAT is included
  • Whether they’re fully insured
  • Whether you can choose the colour

Our hiring checklist

Questions from Horton

Do you cover Horton for fire rated sealant?

Yes. We work across London and the South East, and Horton is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

Do you cover smaller places like Horton?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can tenants book the work?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

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

It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.

What fire rating will the seal have?

We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself, and we’ll mention anything we notice about the door.

Can ordinary silicone be used in a fire-stopping gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.

Do you offer different sealant colours?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Workplaces and buildings in Horton

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.

Letting a property close to Sunnymeads station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Michael are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

What affects the cost of fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • How much there is to do
  • The type of sealant required
  • The old material and how stubborn it is
  • When we can work, for business premises

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • The problem you’ve noticed
  • Roughly how big the job is

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and give you a clear quote.

For landlords and businesses

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

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

What we can’t put right

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

  • Openings too large for sealant, which need batts, boards or another system
  • Fire doors that need new seals, closers or hardware
  • Construction that does not provide fire resistance on its own

If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
