How we handle fire rated sealant in Swerford

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on door frames, service penetrations and pipe & cable gaps, and the jobs we see most are open joints along the top of partitions and cracked or shrunken fire-rated sealant.

Somewhere as small as Swerford, 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.

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

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Leave it or put it right?

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Older cottages and farmhouses around Swerford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Should I try it myself first?

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.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

How to look after the new joints

Aftercare is simple:

  • Plan fire stopping into any work that goes through walls or floors
  • Ask which product was used before you paint
  • Tell trades working in the building that fire seals must be put back
  • Keep pictures of seals that will be hidden

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Questions from Swerford

Is fire rated sealant in Swerford guaranteed?

All our work, in Swerford and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Is Swerford within the area you cover?

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

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Can ordinary silicone be used in a fire-stopping gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Can you match the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

What happens on the day

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Swerford, access is usually the main thing to plan. 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. We measure every gap and note what it’s in and what passes through.
  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. We hand over a list of locations and products for your files.

How to prepare

  • Let us know about earlier repairs to the joints
  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work

How to get a quote

We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.

What the job involves on each surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

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 seal has something sound to bond to.

  • Any access issues, like height or stairs

  • Pictures of the joints, sent by email

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

What fire rated sealant looks like in Swerford

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, which is often where open fire-stopping gaps are first noticed. 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 Mary, service openings in its walls need the right fire-rated sealant, as in any building. In and around Swerford, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.
