About our fire rated sealant in Tipner

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. Common call-outs are for gaps left after a refit or conversion and gaps around pipes and cables through fire-resisting walls, across flats & HMOs, service penetrations and pipe & cable gaps.

Commercial work around a smaller place like Tipner normally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

Big or small, you get the same one-year guarantee.

Signs you need fire rated sealant in Tipner

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Signs it’s time to call us include:

  • Seals cut through by electricians, plumbers or data installers
  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that isn’t fire-rated

For landlords with property near Portsmouth & Southsea station, any gap left by new services in shared walls should be closed with a fire-rated product.

Our hiring checklist

What fire rated sealant looks like in Tipner

For seaside hotels, guest houses and holiday lets around Tipner, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

For site and facilities teams at buildings such as Stamshaw Infant Academy, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as St Saviour's Church, older buildings that have had new heating or wiring often have service gaps worth checking.

How it works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. For a job in Tipner, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Getting ready for the visit

  • Mention if the joints have been sealed before
  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive

Advice

Looking after it afterwards

So the new joints stay in good condition:

  • Include fire stopping when you schedule refits
  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back
  • Report cracked or damaged seals as soon as you notice them

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

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

Questions from Tipner

I let a flat near Portsmouth & Southsea station. Can you help?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.

Can you do fire rated sealant in Tipner?

Yes, Tipner is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

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

An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Is it OK to seal over old sealant?

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

Do I have to be there?

It depends on the job. Inside work needs someone to give us access.

Is the work guaranteed?

Yes, always. There’s a 12-month guarantee on every job, wherever you are.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Surface by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each.
