Fire rated sealant near Gubblecote

Fire rated sealant in Gubblecote, done properly

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. If you’re dealing with new service routes left unsealed after building work and ordinary sealant used where a fire-rated product was needed, we can help.

In a village or hamlet like Gubblecote, 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, whatever its size.

Gubblecote questions

Is Gubblecote in your area for fire rated sealant?

Yes. We work across London and the South East, and Gubblecote 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.

Do you cover smaller places like Gubblecote?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can I do it myself?

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Workplaces and buildings in Gubblecote

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 building such as Long Marston VA Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Cross are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Cheddington station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How it works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Somewhere as small as Gubblecote, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

Preparing for the visit

  • Tell us about any water getting in
  • Mention any parking rules near the property
  • Let us know about stairs, lifts or work at height

What affects the cost of fire rated sealant

Jobs vary more than people expect. The main factors:

  • The size of the job
  • Access and height
  • How many areas need sealing
  • The old material and how stubborn it is

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.

Helping us quote

To help us quote quickly, let us know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • The rough size of the job
  • Where the property is

For fire rated sealant in Gubblecote, call 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

What we can’t put right

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • A wall that isn’t a fire-resisting element to begin with

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Joints and surfaces we work on

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

Different surfaces, different methods

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.

Keeping the joints in good condition

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

  • Check risers, ceiling voids and cupboards during building checks
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Keep pictures of seals that will be hidden
  • Do not paint over fire sealant until it has cured

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Why act early in Gubblecote

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Around Gubblecote, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

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 book with us

  • Tidy, careful work
  • Anti-fungal silicone where joints get wet
  • Approved under the ARBOMaster scheme
  • Old sealant always removed completely

Should I try it myself first?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
