About our fire rated sealant in Leckhampstead

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That’s the part we focus on. We work on pipe & cable gaps, door frames and plasterboard & masonry, and people most often call us about door frames with gaps between frame and wall and cracked or shrunken fire-rated sealant.

In a village or hamlet like Leckhampstead, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

There’s a 12-month guarantee on every job, whatever its size.

What we are called out for in Leckhampstead

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.

People usually contact us after spotting something like this:

  • Unsealed gaps around fire door frames
  • New service routes left unsealed after building work
  • Fire stopping disturbed by later work
  • Open holes round services passing through fire walls

Community buildings like Church of St James are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Questions from Leckhampstead

Is Leckhampstead in your area for fire rated sealant?

Yes, Leckhampstead is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

What guarantee comes with fire rated sealant in Leckhampstead?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Do you certify the fire stopping?

We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it with a record of each location.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

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

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Early starts or out-of-hours work can be arranged.

When something else is needed

We will not take on work that will not last, so these are the limits:

  • Issuing a fire rating or certificate for a building
  • Large holes that need a different fire-stopping system
  • A wall that is not a fire-resisting element to begin with

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

What we seal

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

Leave it or put it right?

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Leckhampstead, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

How it works

When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Leckhampstead, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

How to prepare

  • Tell us about any water getting in
  • Let us know about parking restrictions
  • On commercial sites, let us know about site rules

How the job changes by surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we’re sealing.

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth.

Quotes for fire rated sealant in Leckhampstead

Jobs vary more than people expect. What affects the quote:

  • Which sealant suits the joint
  • When we can work, for business premises
  • How many areas need sealing
  • Any mould that needs treating

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

You don’t need to know the technical terms. Just tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • Any access issues, like height or stairs
  • The address or postcode of the job

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
