Fire rated sealant for Great Coxwell homes and businesses

How it works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Somewhere as small as Great Coxwell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we’re working on
  • Mention if the joints have been sealed before

Advice

How we handle fire rated sealant in Great Coxwell

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 gaps where walls meet ceilings or slabs and unsealed gaps around fire door frames, on door frames, flats & HMOs and plasterboard & masonry.

Somewhere as small as Great Coxwell, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

All our work comes with our one-year guarantee, wherever you are in Oxfordshire.

What the job involves on each surface

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Look in service cupboards and ceiling voids from time to time
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief
  • Store the list of sealed gaps with your building paperwork

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

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

When it is not the sealant

Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant will not put right:

  • Doors that aren’t fire doors in the first place
  • Certifying a building or signing off its fire safety
  • Construction that does not provide fire resistance on its own

If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

Surfaces we seal

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

Great Coxwell: your questions answered

Is there a guarantee on fire rated sealant in Great Coxwell?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Do you cover smaller places like Great Coxwell?

Yes, Great Coxwell is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.

What fire rating will the seal have?

We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.

Can I use normal mastic around a pipe through a fire wall?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Commercial buildings in Great Coxwell

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

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

What we are called out for in Great Coxwell

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

Any of these means the joints need attention:

  • Ordinary sealant used where a fire-rated product was needed
  • Fire seals that have cracked with movement
  • Fire stopping disturbed by later work
  • Open gaps behind door architraves

If you look after a building such as Faringdon Community College, service openings in fire-resisting walls need checking after any refurbishment.

  • Whether all the old sealant comes out first
  • Whether VAT is included
  • How hidden problems are handled

Choosing a sealant specialist

What happens if it’s left?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. Where a wall is exposed, as many are in small places like Great Coxwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
