FAQs for Slaugham

Do you cover Slaugham for fire rated sealant?

Yes. Our work covers London and the South East, and Slaugham is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

Is Slaugham within the area you cover?

Yes. Slaugham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

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, installed to its details.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Are you fully insured?

Yes. We are fully insured.

Will the old sealant be removed?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

I rent my home. Can I book you?

Of course. Check with your landlord; we can send the quote to them too.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.

About our fire rated sealant in Slaugham

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. Typical jobs include seals cut through by electricians, plumbers or data installers and sealant items on a fire risk assessment action list, on flats & HMOs, door frames and linear gaps.

If you have holiday lets, a converted barn used for business or a community building near Slaugham, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Whatever the size of the job, it’s backed by our one-year guarantee.

What happens on the day

Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Slaugham, 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 plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before

When to call us in Slaugham

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

The problems people generally mention when they call are:

  • Fire stopping disturbed by later work
  • Open holes round services passing through fire walls
  • Gaps filled with a product that is not fire-rated
  • Cracked or shrunken fire-rated sealant

Letting a property close to Balcombe station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Before booking anyone

  • How the surfaces are prepared before sealing
  • What the quote includes, VAT included or not
  • What the cure time is
  • Whether the sealant suits the joint

Our hiring checklist

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Slaugham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Why us?

  • Experience in homes, commercial sites and hotels
  • An ARBOMaster approved applicator
  • Fully insured
  • Anti-fungal sanitary silicone in wet areas

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Don’t paint over fire sealant until it has cured
  • Never patch a fire seal with standard sealant
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded.

How we quote for fire rated sealant

The price is agreed before any work begins. It takes into account:

  • How much old sealant there is and how hard it is to remove
  • When we can work, for business premises
  • Whether there’s mould to deal with
  • Whether the work is at height

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Asking for a quote

When you contact us, these details help:

  • The problem you’ve noticed
  • The rough size of the job
  • Where the job is, and your postcode
  • If it’s domestic, commercial or a hotel

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

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.

Commercial buildings in Slaugham

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.

If you look after a building such as Warninglid Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like St Mary's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Construction that doesn’t provide fire resistance on its own
  • Assessing a building’s fire safety
  • Doors that aren’t fire doors in the first place
