Trusted fire rated sealant in Fish Island

Do you need fire rated sealant in Fish Island?

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

Keep an eye out for any of the following:

  • Gaps where walls meet ceilings or slabs
  • Door frames with gaps between frame and wall
  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps where pipes and cables go through a wall

For buildings such as St Mary of Eton, gaps around pipes and cables are worth checking after any building work there.

Fire rated sealant in Fish Island, done properly

Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment. Send us the list or the survey and we will quote for the fire-rated sealant work on it. Typical jobs include old fire sealant that has split or come away and unsealed gaps where pipes and cables go through a wall, across door frames, linear gaps and flats & HMOs.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Fish Island, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Workplaces and buildings in Fish Island

Fish Island has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.

As a London address, Fish Island can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Hackney Wick station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What sealant work can’t fix

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

  • Large holes that need a different fire-stopping system
  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire

If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Door frames
  • Service penetrations

  • Linear gaps
  • Pipe & cable gaps

Why act early in Fish Island

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Fish Island.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Why book with us

  • We leave the area clean and tidy
  • Domestic, commercial and hotel work
  • Every job guaranteed for a year
  • Anti-fungal silicone where joints get wet

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Working hours on commercial sites
  • The old material and how stubborn it is
  • The number and length of the joints
  • Access and height

Combining jobs into one visit usually 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

To help us quote quickly, let us know:

  • Any previous sealing or DIY work
  • If it’s domestic, commercial or a hotel
  • Photos by email, if that’s easy
  • The address or postcode of the job

If you’re in Fish Island and need fire rated sealant, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

The process

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. In Fish Island, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any parking rules near the property

Advice

For landlords and businesses

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.

How the job changes by surface

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Common questions in Fish Island

Do you work in hotels near Fish Island?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Is parking a problem for a job in Fish Island?

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 you seal over the old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Can I add another job to the visit?

Of course. Doing several areas at once is usually more efficient.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we will tell you if we spot problems with the door.

Will we have a record of what was sealed?

Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
