Fire rated sealant in Wimbledon Park

Fire rated sealant in Wimbledon Park

Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. Typical jobs include open holes round services passing through fire walls and gaps where walls meet ceilings or slabs, on pipe & cable gaps, flats & HMOs and service penetrations.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Wimbledon Park needs to stay open, work can be planned outside normal hours.

Our work is backed for twelve months, in Wimbledon Park and everywhere else we cover.

Why it’s worth doing now in Wimbledon Park

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Wimbledon Park, the repair is bigger than the sealant job would have been.

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Signs you need fire rated sealant in Wimbledon Park

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.

These are the problems we are asked about most:

  • Ordinary sealant used where a fire-rated product was needed
  • Fire stopping disturbed by later work
  • Old fire sealant that has split or come away
  • Unsealed gaps around fire door frames

For site and facilities teams at buildings such as Albemarle Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What your quote should include

  • What the cure time is
  • What insurance they hold
  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it

How the job changes by surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

Your questions about fire rated sealant in Wimbledon Park

Can parking be tricky for a visit in Wimbledon Park?

Parking in Wimbledon Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you take on hotel work around Wimbledon Park?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

What does fire rated sealant cost?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check whether a sealant can be painted before decorating over it
  • Store the list of sealed gaps with your building paperwork
  • Keep pictures of seals that will be hidden
  • Do not fill fire-stopping gaps with ordinary foam or silicone

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.

Fire rated sealant in Wimbledon Park: local notes

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. There are hotels and other places to stay in and around Wimbledon Park. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a church, hall or community building such as Church of St Luke, older buildings that have had new heating or wiring often have service gaps worth checking. Wimbledon Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Should I try it myself first?

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

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

How the visit works

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Wimbledon Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  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. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
