Fire rated sealant in Duckett's Green, done properly

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We’re often asked to deal with linear gaps at the head of walls and damaged fire sealant left by other trades, on plasterboard & masonry, pipe & cable gaps and flats & HMOs.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Duckett's Green cannot close.

All our work comes with a 12-month guarantee, wherever you are in Greater London.

Why deal with it now?

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Duckett's Green.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Why book with us

  • Approved under the ARBOMaster scheme
  • 20+ years of sealant experience
  • Tidy, careful work
  • One-year guarantee on every job

Fire rated sealant around Duckett's Green

Duckett's Green has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 work to the specification you are given, installing the product to its tested details.

If you look after a church, hall or community building such as Christ Church, service openings in its walls need the right fire-rated sealant, as in any building. Duckett's Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Landlords, agents and businesses in Duckett's Green

For anyone letting property in or around Duckett's Green, several properties can be quoted together. Just tell us the addresses and what each one needs.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

How we quote for fire rated sealant

There’s no set price list, because no two jobs are the same. What we look at:

  • The number of rooms or windows
  • Any mould that needs treating
  • The product the joint needs
  • When we can work, for business premises

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • If someone has resealed it before
  • How we’d reach the joints
  • The type of property
  • Where the property is

To get a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear price before any work starts.

How it works

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In Duckett's Green, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  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.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • For business premises, tell us about site rules or sign-in
  • Let us know about stairs, lifts or work at height

Signs you need fire rated sealant in Duckett's Green

Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.

The problems people normally mention when they call include:

  • Damaged fire sealant left by other trades
  • Old fire sealant that has split or come away
  • New service routes left unsealed after building work
  • Door frames with gaps between frame and wall

Letting a property close to Hornsey station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before you book

  • What the quote includes, VAT included or not
  • Whether they seal over old material or remove it
  • How the colour is chosen
  • What product goes in the joint

Our hiring checklist

What we can’t put right

It helps to know what we can’t do too:

  • Deciding what fire stopping a building needs
  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system

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

Joints and surfaces we work on

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

Questions from Duckett's Green

Is parking a problem for a job in Duckett's Green?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you work for landlords with property near Hornsey station?

Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Duckett's Green, along with the rest of our area.

How do I get a quote for fire rated sealant in Duckett's Green?

Size, access and the old material all affect the cost. Call for a quick quote.

Can ordinary silicone be used in a fire-stopping gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

How long does fire rated sealant take?

Most jobs take anything from a few hours to several days, depending on how many gaps there are. We will confirm how long when we quote.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.

Is there any odour?

Some sealants have a smell while they cure. Ventilation helps.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Ask every contractor to reseal any fire stopping they disturb
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Look in service cupboards and ceiling voids from time to time
  • Keep the record of products and locations with your fire safety documents

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.
