Fire rated sealant in Dormans Park

About our fire rated sealant in Dormans Park

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, and we can record what went where. Common call-outs are for gaps around pipes and cables through fire-resisting walls and ordinary sealant used where a fire-rated product was needed, on plasterboard & masonry, linear gaps and service penetrations.

For holiday lets, converted business premises or a community building near Dormans Park, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

What affects the quote in Dormans Park

The quote reflects the job in front of us. We look at:

  • How much there is to do
  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

Asking for a quote

You don’t need to know the technical terms. It helps if you can tell us:

  • A few photos by email, if you can
  • Access, such as stairs, a lift or height
  • If someone has resealed it before
  • How many joints, rooms or windows are involved

Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.

What happens on the day

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Dormans Park, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces 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.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Let us know about stairs, lifts or work at height
  • Mention any leaks or damp you’ve noticed

Advice

Common questions in Dormans Park

Is Dormans Park in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Dormans Park is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.

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

Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

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

No. Where a fire-rated seal is needed, it has to be a product tested for that use.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

Will there be a smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Does someone need to be in?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

When it isn’t the sealant

We will always be straight with you, so here’s what sealant cannot fix:

  • Construction that does not provide fire resistance on its own
  • Certifying a building or signing off its fire safety
  • Deciding what fire stopping a building needs

If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.

What we seal

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

Fire rated sealant in Dormans Park: local notes

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, 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.

Schools such as Bush Davies School of Theatre Arts are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St John the Evangelist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

When to call us in Dormans Park

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.

People usually contact us after spotting something like this:

  • Gaps flagged on a fire risk assessment
  • Fire stopping disturbed by later work
  • Standard silicone or caulk in a fire-stopping gap
  • Door frames with gaps between frame and wall

For landlords with property near Dormans station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What your quote should include

  • Who does the work, and how experienced they are
  • Whether they’re fully insured
  • Which sealant they’ll use, and why
  • When the joint can take water or movement

Choosing a sealant specialist

Surface by surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.

What happens if it’s left?

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again once someone inspects it. In a small place like Dormans Park, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
