Can I do it myself?

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.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Fire rated sealant in Peaks Hill, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. Common call-outs are for sealant items on a fire risk assessment action list and seals cut through by electricians, plumbers or data installers, across door frames, service penetrations and plasterboard & masonry.

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 Peaks Hill needs to stay open, work can be planned outside normal hours.

A one-year guarantee comes as standard, so you are covered after we’ve gone.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Problems with the door itself rather than the gap around the frame
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

How the visit works

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are. In Peaks Hill, 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. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the gap 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 records.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks

Advice

Common problems we fix in Peaks Hill

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 round the new service is not always sealed again.

The problems people usually mention when they call include:

  • Sealant items on a fire risk assessment action list
  • Gaps where walls meet ceilings or slabs
  • Fire stopping disturbed by later work
  • Standard silicone or caulk in a fire-stopping gap

As a London address, Peaks Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

Quotes for fire rated sealant in Peaks Hill

Some jobs are bigger than they look, and some smaller. The main factors:

  • The number and length of the joints
  • Whether the work is at height
  • When we can work, for business premises
  • The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • Whether it has been sealed before
  • A few photos by email, if you can
  • How many joints, rooms or windows are involved
  • What’s wrong with the joints now

We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.

Fire rated sealant around Peaks Hill

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

For buildings such as Church of St Mark, gaps around pipes and cables are worth checking after any building work there. Rented homes near Purley station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

FAQs for Peaks Hill

Can you help a landlord with a rental near Purley station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Is parking an issue for fire rated sealant in Peaks Hill?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Will we have a record of what was sealed?

Yes. Every gap we seal is listed with the product used.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Will there be a smell?

It depends on the product. Some smell for a while, some hardly at all.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

What the job involves on each surface

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.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
