Fire rated sealant in Hayes

How we handle fire rated sealant in Hayes

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. We work on flats & HMOs, pipe & cable gaps and door frames, and people most often call us about joints picked up in a fire-stopping survey and new service routes left unsealed after building work.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Hayes cannot close.

All of our work is guaranteed for twelve months.

The process

On the day, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Getting ready for the visit

Advice

Your questions about fire rated sealant in Hayes

Do you work for landlords with property near Hayes & Harlington station?

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

Is parking a problem for a job in Hayes?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Are you an approved applicator?

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

Do you come to Hayes?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Hayes.

Honest limits

In fairness, some problems need a different trade:

  • Construction that doesn’t provide fire resistance on its own
  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building

If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Joints and surfaces we work on

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

Surface by surface

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first.

Leave it or put it right?

Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. 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 Hayes, the repair is bigger than the sealant job would have been.

The cost depends on the amount of work, 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.

When to call us in Hayes

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Any of these means the joints need attention:

  • Gaps left after a refit or conversion
  • Gaps filled with a product that is not fire-rated
  • Sealant items on a fire risk assessment action list
  • Open gaps behind door architraves

Rented homes near Hayes & Harlington station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What your quote should include

  • What insurance they hold
  • What happens if the job turns out different
  • The length of the guarantee
  • Is the old sealant removed completely?

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Never patch a fire seal with standard sealant
  • Check risers, ceiling voids and cupboards during building checks
  • Flag any open gap you spot round a pipe or cable
  • Ask which product was used before you paint

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t and we will tell you which one you have.

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