Trusted fire rated sealant in Worcester Park

Why act early in Worcester Park

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

How we handle fire rated sealant in Worcester Park

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have gaps flagged on a fire risk assessment and holes left by a change of layout, we can put it right, whatever the surface.

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 Worcester Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

There’s a 12-month guarantee on every job.

Signs you need fire rated sealant in Worcester Park

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The most common problems we see are:

  • Joints picked up in a fire-stopping survey
  • Unsealed gaps around fire door frames
  • Linear gaps at the head of walls
  • New service routes left unsealed after building work

If you let a flat or house near Worcester Park station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Before you book anyone

  • Is the old sealant removed completely?
  • Is VAT in the price?
  • How the surfaces are prepared before sealing
  • How much experience the applicator has

Choosing a sealant specialist

Looking after it afterwards

To keep the joints looking good and working properly:

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Ask every contractor to reseal any fire stopping they disturb
  • Check risers, ceiling voids and cupboards during building checks
  • Don’t paint over fire sealant until it has cured

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.

How it works

We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Worcester Park. It helps if you can point us to a visitor permit or a bay close to the door.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Workplaces and buildings in Worcester Park

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Cuddington Community Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Worcester Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Different surfaces, different methods

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.

When it is not the sealant

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
  • Construction that doesn’t provide fire resistance on its own
  • Deciding what fire stopping a building needs

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