About our fire rated sealant in Clapton

Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Clapton. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on plasterboard & masonry, pipe & cable gaps and service penetrations, and common reasons people get in touch are standard silicone or caulk in a fire-stopping gap and gaps flagged on a fire risk assessment.

In a village or hamlet like Clapton, 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.

Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What happens on the day

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Clapton, 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. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your files.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Advice

Common questions in Clapton

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

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Is Clapton within the area you cover?

Yes, Clapton is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

What sealant do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.

Do you certify the fire stopping?

That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.

Where are you based?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Can new sealant go over the old?

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.

Do you work in flats, HMOs and commercial buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.

What do you need from me for a quote?

Tell us what needs doing and where, with photos by email if possible. If we need more, we will ask.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Photograph sealed gaps before they’re covered up
  • Don’t paint over fire sealant until it has cured
  • Keep the record of products and locations with your fire safety documents
  • Make resealing part of every contractor’s brief

Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

Common problems we fix in Clapton

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Signs it’s time to call us include:

  • Unsealed gaps where pipes and cables go through a wall
  • Old fire sealant that has split or come away
  • Gaps where walls meet ceilings or slabs
  • Sealant items on a fire risk assessment action list

Community buildings like Church of St Swithin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What to look for in a quote

  • Are they insured?
  • How much experience the applicator has
  • Whether VAT is included
  • Whether all the old sealant comes out first

How the job changes by surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

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.

How we quote for fire rated sealant

The quote reflects the job in front of us. We look at:

  • When we can work, for business premises
  • The number of rooms or windows
  • The amount of work
  • Whether there’s mould to deal with

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

When you contact us, these details help:

  • The rough size of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business

There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or send us an email.
