Fire rated sealant in Martin

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. Those are the gaps we close, using a tested fire-rated product. If you have linear gaps at the head of walls and fire stopping disturbed by later work, we can help, whatever the surface.

In a village or hamlet like Martin, 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.

Whatever the size of the job, you get the same one-year guarantee in Martin and across Hampshire.

Common problems we fix in Martin

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.

It’s worth asking for a quote if you see:

  • Fire stopping disturbed by later work
  • Gaps filled with a product that isn’t fire-rated
  • Cracked or shrunken fire-rated sealant
  • Gaps where walls meet ceilings or slabs

Around Martin, as everywhere, fire rated sealant is only as good as the preparation behind it.

Quotes for fire rated sealant in Martin

For a quick quote, just ask. What matters most is:

  • How much old sealant there is and how hard it is to remove

What to tell us for a quote

  • Any previous sealing or DIY work
  • What’s wrong with the joints now
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.

What fire rated sealant looks like in Martin

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.

If you look after a church, hall or community building such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.

How do I get a quote for fire rated sealant in Martin?

Size, access and the old material all affect the cost. Ask us for a quote.

Is it OK to seal over old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Can you match the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Do you guarantee your work?

Yes. All our work carries our one-year guarantee.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What we do, step by step

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Martin, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  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.

Preparing for the visit

  • Clear the area around the work

Aftercare tips

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep the record of products and locations with your fire safety documents
  • Plan fire stopping into any work that goes through walls or floors
  • Flag any open gap you spot round a pipe or cable
  • Ask every contractor to reseal any fire stopping they disturb

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

How the job changes by surface

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
