What affects the cost of fire rated sealant

Your quote is based on your job. We look at:

  • Which sealant suits the joint
  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • Any working-time requirements on site

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • A few photos by email, if you can
  • If someone has resealed it before
  • Where the property is
  • How many joints, rooms or windows are involved

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Photograph sealed gaps before they’re covered up
  • Look in service cupboards and ceiling voids from time to time
  • Plan fire stopping into any work that goes through walls or floors

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.

Capel questions

Can you help a landlord with a rental near Ockley station?

Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

Do you cover Capel for fire rated sealant?

Yes, Capel is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

What does fire rated sealant cost?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

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 list the locations and products for you.

What does intumescent mean?

An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

Why act early in Capel

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Where a wall is exposed, as many are in small places like Capel, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the job changes by surface

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length leaving no stretch unsealed.

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail and we flag any that need another system.

How it works

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Capel, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about earlier repairs to the joints

When to call us in Capel

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.

Common reasons people contact us include:

  • Linear gaps at the head of walls
  • Open gaps behind door architraves
  • Gaps flagged on a fire risk assessment
  • Gaps filled with a product that is not fire-rated

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

What sealant work can’t fix

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Issuing a fire rating or certificate for a building
  • Construction that doesn’t provide fire resistance on its own
  • Fire risk assessments, which need a qualified assessor

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

Surfaces we seal

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

Commercial buildings in Capel

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.

Community buildings like Church of St John the Baptist are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Scott Broadwood CofE Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.
