Barnsole questions

Will you come out to Barnsole?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is Barnsole in your area for fire rated sealant?

Yes, Barnsole is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How much does fire rated sealant cost in Barnsole?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Is the work guaranteed?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Fire rated sealant for homes and businesses in Barnsole

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have new service routes left unsealed after building work and door frames with gaps between frame and wall, we can put it right, whatever the surface.

For holiday lets, converted business premises or a community building near Barnsole, 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 12-month guarantee.

Why deal with it now?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a small place like Barnsole, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Why book with us

  • Experience in homes, commercial sites and hotels

When something else is needed

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Sign-off of the building, which sits with building control or your assessor
  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

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

Common problems we fix in Barnsole

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

The problems people normally mention when they call include:

  • Joints picked up in a fire-stopping survey
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps left after a refit or conversion
  • Fire seals that have cracked with movement

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

Our hiring checklist

What fire rated sealant looks like in Barnsole

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.

Community buildings like Church of St James are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

How the visit works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Barnsole, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Tell us about any water getting in
  • Clear items away from the joints we are working on
  • Mention any tricky access

How to get a quote

Related advice

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Check risers, ceiling voids and cupboards during building checks
  • Report cracked or damaged seals as soon as you notice them
  • Photograph sealed gaps before they’re covered up
  • Ask every contractor to reseal any fire stopping they disturb

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.

Should I try it myself first?

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.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What affects the quote in Barnsole

You will get a clear quote before any work starts. It takes into account:

  • Any working-time requirements on site
  • The old material and how stubborn it is
  • How many areas need sealing
  • Whether the work is at height

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • 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
  • Where the property is

For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
