How we handle fire rated sealant in Maypole

Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on pipe & cable gaps, service penetrations and plasterboard & masonry, and common reasons people get in touch are gaps flagged on a fire risk assessment and unsealed gaps where pipes and cables go through a wall.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Maypole, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Honest limits

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Deciding what fire stopping a building needs
  • A wall that is not a fire-resisting element to begin with
  • Certifying a building or signing off its fire safety

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Joints and surfaces we work on

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

Why deal with it now?

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Maypole.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Why book with us

  • Anti-fungal silicone where joints get wet
  • Old sealant always removed completely
  • Neat joints and a tidy finish
  • One-year guarantee on every job

What the job involves on each surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Store the list of sealed gaps with your building paperwork
  • Report cracked or damaged seals as soon as you notice them

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

For landlords and businesses

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Your questions about fire rated sealant in Maypole

Is Maypole in your area for fire rated sealant?

Yes. We work across London and the South East, and Maypole is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

I let a flat near Knockholt station. Can you help?

Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

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

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

What does intumescent mean?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Will there be a smell?

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

What happens on the day

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In Maypole, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Move anything stored near the joints
  • For indoor joints, keep the area dry beforehand if you can
  • Keep children and pets away from the work area

Advice

Commercial buildings in Maypole

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, 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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

Letting a property close to Knockholt station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Mission Chapel, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Chelsfield Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How we quote for fire rated sealant

We do not publish a price list. The quote depends on:

  • Any mould that needs treating
  • Whether the work is at height
  • The number and length of the joints
  • The number of rooms or windows

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Asking for a quote

To make quoting easier, please include:

  • How we’d reach the joints
  • Whether it has been sealed before
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
