How we handle fire rated sealant in Winterbourne

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. Typical jobs include gaps left after a refit or conversion and seals cut through by electricians, plumbers or data installers, on service penetrations, pipe & cable gaps and linear gaps.

For a small place like Winterbourne, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Landlords, agents and businesses in Winterbourne

Housing providers, facilities teams and property managers book us too in Winterbourne and across West Berkshire. Several sites can be quoted together.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

When to call us in Winterbourne

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

Look out for any of the following:

  • Unsealed gaps around fire door frames
  • Fire seals that have cracked with movement
  • Open holes round services passing through fire walls
  • Holes left by a change of layout

If you let a flat or house near Newbury station, any gap left by new services in shared walls should be closed with a fire-rated product.

Our hiring checklist

Fire rated sealant around Winterbourne

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, 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 James, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Mary Hare School? Then service openings in fire-resisting walls need checking after any refurbishment.

Common questions in Winterbourne

Can you do fire rated sealant in Winterbourne?

Yes, Winterbourne is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.

Do you cover smaller places like Winterbourne?

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.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

Are you insured?

Yes, we’re fully insured for every job we do.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

How we quote for fire rated sealant

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

  • Access and height
  • Which sealant suits the joint
  • How much there is to do
  • Whether old sealant or filler has to be cut out

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

What to tell us for a quote

When you call or email, these details help:

  • Where the job is, and your postcode
  • A few pictures by email, if you can
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before

If you’re in Winterbourne and need fire rated sealant, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

What happens on the day

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Winterbourne needs a little journey planning: 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. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out 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 files.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any sign-in or site rules at work premises

Getting a quote

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.

Advice

What happens if it’s left?

Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Winterbourne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Why us?

  • More than 20 years in sealant work
  • Old sealant always removed completely
  • Rated 4.9 stars on Google
  • We leave the area clean and tidy

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Get damaged fire seals looked at promptly
  • Plan fire stopping into any work that goes through walls or floors
  • Include hidden areas like risers in routine checks

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

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
