What affects the cost of fire rated sealant

Call for a quick quote. The main things that affect it are:

  • Whether the work is at height
  • The product the joint needs
  • Any mould that needs treating
  • How many areas need sealing

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Helping us quote

Before you ask for a quote, have a think about:

  • Access, such as stairs, a lift or height
  • Where the property is
  • Photos by email, if that’s easy
  • How many joints, rooms or windows are involved

If you’re in Alfold and need fire rated sealant, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.

Fire rated sealant in Alfold

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on plasterboard & masonry, door frames and linear gaps, and the jobs we see most are gaps flagged on a fire risk assessment and linear gaps at the head of walls.

In a village or hamlet like Alfold, 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.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • File the fire-stopping record where your assessor can find it
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Ask which product was used before you paint
  • Look in service cupboards and ceiling voids from time to time

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Signs you need fire rated sealant in Alfold

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

Most people get in touch after spotting one of these:

  • Gaps where walls meet ceilings or slabs
  • Open gaps behind door architraves
  • Standard silicone or caulk in a fire-stopping gap
  • Old fire sealant that has split or come away

Around Alfold, as everywhere, fire rated sealant is only as good as the preparation behind it.

Choosing a sealant specialist

Why it’s worth doing now in Alfold

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Where a wall is exposed, as many are in small places like Alfold, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.

Alfold questions

Is Alfold within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

What guarantee comes with fire rated sealant in Alfold?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

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

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

How long will you be here?

Most jobs take a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Will you assess my building’s fire safety?

No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

What we do, step by step

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Alfold, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. 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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Move anything stored near the joints
  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children

Advice

Commercial buildings in Alfold

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.

Community buildings like Church of St Nicholas are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
