Fire rated sealant for Hanworth homes and businesses

Fire rated sealant for homes and businesses in Hanworth

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We are often asked to deal with sealant items on a fire risk assessment action list and gaps where walls meet ceilings or slabs, on service penetrations, 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, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Hanworth cannot close.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

What sealant work cannot fix

Before you book, it’s worth knowing the limits too:

  • Certifying a building or signing off its fire safety
  • Fire doors that need new seals, closers or hardware
  • Openings too large for sealant, which need batts, boards or another system

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

What affects the quote in Hanworth

There’s no set price list, because jobs vary so much. The quote depends on:

  • How many areas need sealing
  • Whether the work is at height
  • The type of sealant required
  • The size of the job

Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • Roughly how big the job is
  • Access, such as stairs, a lift or height
  • The type of property
  • A few pictures by email, if you can

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and give you a clear price.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Do not paint over fire sealant until it has cured
  • Keep the record of products and locations with your fire safety documents
  • Include fire stopping when you schedule refits
  • Photograph sealed gaps before they’re covered up

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we will tell you which one you have.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Why deal with it now?

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Hanworth, the repair is bigger than the sealant job would have been.

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Why us?

  • One-year guarantee on every job
  • Tidy, careful work
  • Quality sealants from Arbo and Everbuild
  • Experience in homes, commercial sites and hotels

Do you need fire rated sealant in Hanworth?

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.

Most people get in touch after spotting one of these:

  • Unsealed gaps around fire door frames
  • Fire stopping disturbed by later work
  • Fire seals that have cracked with movement
  • New service routes left unsealed after building work

Hanworth is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Questions to ask before booking

  • Are they insured?
  • What happens if they find a problem under the old sealant
  • What guarantee comes with the work
  • How the colour is chosen

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. In a London area like Hanworth, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Let us know about parking restrictions
  • Mention any sign-in or site rules at work premises
  • Plan for the work area to be out of bounds to pets and children

What fire rated sealant looks like in Hanworth

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.

Rented homes near Hampton station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Buckingham Primary School, fire-stopping around service openings should be restored whenever new services go in.

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Can I use normal mastic around a pipe through a fire wall?

No. A gap that needs fire stopping needs a tested fire-rated product.

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.

Do you provide details of the products used?

Yes. We note each location and the product that went in so it’s there for the next inspection.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done and you’ll get one quote.
