Fire rated sealant near Park Royal

Fire rated sealant for homes and businesses in Park Royal

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on service penetrations, linear gaps and pipe & cable gaps, and people most often call us about fire seals that have cracked with movement and damaged fire sealant left by other trades.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Park Royal, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.

Whatever the size of the job, it’s backed by our one-year guarantee.

What affects the quote in Park Royal

There’s no set price list, because jobs vary so much. What we look at:

  • How many areas need sealing
  • The product the joint needs
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email.

Asking for a quote

Photos by email are helpful but not essential. Try to tell us:

  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • The type of property
  • The address or postcode of the job

We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details.

Landlord and commercial work in Park Royal

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Looking after it afterwards

So the new joints stay in good condition:

  • Get damaged fire seals looked at promptly
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Photograph sealed gaps before they’re covered up
  • Ask every contractor to reseal any fire stopping they disturb

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

What happens if it’s left?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

What it costs depends on how much there is to do, how much old material has to come out 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

  • Tidy, careful work
  • We’re fully insured
  • Over 20 years’ experience
  • Anti-fungal sanitary silicone in wet areas

What happens on the day

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. For a job in Park Royal, 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. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  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 files.

Before we arrive

  • On commercial sites, let us know about site rules
  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before

Fire rated sealant in Park Royal: local notes

Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

Letting a property close to Harlesden station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as St Gabriel's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like West Twyford Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Park Royal: your questions answered

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

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

Do you take on hotel work around Park Royal?

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.

Will we have a record of what was sealed?

Yes. You get a list of where we worked and what we used for your files.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you fill the gap behind a fire door frame?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.

Can I choose the sealant colour?

We help you choose a colour that suits. The product needed can limit the range.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

When something else is needed

In fairness, some problems need a different trade:

  • Walls or floors that weren’t built to resist fire
  • Certifying a building or signing off its fire safety
  • Fire risk assessments, which need a qualified assessor

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
