Fire rated sealant in Dormansland

Common problems we fix in Dormansland

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.

These are the problems we are asked about most:

  • Seals cut through by electricians, plumbers or data installers
  • Unsealed gaps where pipes and cables go through a wall
  • Gaps filled with a product that is not fire-rated
  • Unsealed gaps around fire door frames

For buildings such as St John the Evangelist, gaps around pipes and cables are worth checking after any building work there.

What your quote should include

  • How much experience the applicator has
  • What happens if they find a problem under the old sealant
  • What insurance they hold
  • What product goes in the joint

Choosing a sealant specialist

Fire rated sealant in Dormansland, done properly

Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. Common call-outs are for standard silicone or caulk in a fire-stopping gap and cracked or shrunken fire-rated sealant, across flats & HMOs, plasterboard & masonry and door frames.

Work in a small place like Dormansland is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

All of our work is guaranteed for twelve months.

Dormansland questions

Is Dormansland in your area for fire rated sealant?

Yes. We work across London and the South East, and Dormansland is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

Do you cover smaller places like Dormansland?

Yes, Dormansland is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you match the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.

Can you work in occupied buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged where it’s needed.

I’m a tenant. Can you help?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Can you seal over the old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

How do I get a quote for fire rated sealant in Dormansland?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Sign-off of the building, which sits with building control or your assessor
  • A wall that isn’t a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame

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

What we seal

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

What the job involves on each surface

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

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.

Fire rated sealant around Dormansland

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.

Rented homes near Dormans station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Dormansland Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

The process

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Dormansland, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Tell us if parking is tricky
  • Clear the area around the work
  • Tell us about any previous sealing or DIY attempts

Advice

How to look after the new joints

After the cure time, these simple habits help:

  • Allow for resealing whenever new services are run
  • Get damaged fire seals looked at promptly
  • File the fire-stopping record where your assessor can find it
  • Make resealing part of every contractor’s brief

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

What affects the cost of fire rated sealant

You’ll get a clear quote before any work starts. It’s based on:

  • The number of rooms or windows
  • Whether the work is at height
  • Which sealant suits the joint
  • Whether old sealant or filler has to be cut out

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Asking for a quote

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

  • If someone has resealed it before
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode
  • Photos by email, if that’s easy
