Fire rated sealant in Leigh

Fire rated sealant in Leigh, done properly

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. If you’re dealing with gaps left after a refit or conversion and fire seals that have cracked with movement, we can help, whatever the surface.

For a small place like Leigh, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

Our work is backed for twelve months, in Leigh and everywhere else we cover.

Looking after it afterwards

Looking after new joints is easy:

  • Look in service cupboards and ceiling voids from time to time
  • Plan fire stopping into any work that goes through walls or floors
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we will tell you. Around Leigh, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

When something else is needed

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Big openings where sealant alone isn’t the tested solution
  • Certifying a building or signing off its fire safety
  • Doors that are not fire doors in the first place

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

How we quote for fire rated sealant

There’s no set price list, because jobs vary so much. What we look at:

  • The number and length of the joints
  • Working hours on commercial sites
  • Whether the work is at height
  • The type of sealant required

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • Photos by email, if that is easy
  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is

Every job is quoted individually. Simply phone 0345 464 0079 or email us and describe the job and send photos if you have them.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. Somewhere as small as Leigh, 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. We take out any damaged or unsuitable sealant.
  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. We record what was done and flag anything that needs a different system.

Before we arrive

  • On commercial sites, let us know about site rules
  • Mention any parking rules near the property
  • Keep children and pets away from the work area

Advice

What fire rated sealant looks like in Leigh

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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

For site and facilities teams at buildings such as Leigh Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Do you need fire rated sealant in Leigh?

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

If you can see any of these, it’s time to have the joints looked at:

  • Fire stopping disturbed by later work
  • Linear gaps at the head of walls
  • Gaps filled with a product that isn’t fire-rated
  • Unsealed gaps where pipes and cables go through a wall

Letting a property close to Leigh (Kent) station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
