About our fire rated sealant in Heathfield

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on plasterboard & masonry, linear gaps and flats & HMOs, and the jobs we see most are seals cut through by electricians, plumbers or data installers and old fire sealant that has split or come away.

Community buildings, schools and small businesses around places like Heathfield have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

Every job is covered by our one-year guarantee, wherever you are in East Sussex.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. Parking around Heathfield is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  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. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Let us know about parking restrictions
  • Mention any leaks or damp you’ve noticed
  • Mention any tricky access

Heathfield questions

What guarantee comes with fire rated sealant in Heathfield?

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

Will you come out to Heathfield?

Yes, Heathfield is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you hold any approvals?

Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Can you do several jobs on one visit?

Of course. Doing several areas at once is usually more efficient.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Fire rated sealant in Heathfield: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

For site and facilities teams at buildings such as Parkside Community Primary School, fire-stopping around service openings should be restored whenever new services go in.

Surface by surface

Door frames

Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. In an older home around Heathfield, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Keep the record of products and locations with your fire safety documents
  • Check whether a sealant can be painted before decorating over it
  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.

How we quote for fire rated sealant

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

  • The amount of work
  • Whether the work is at height
  • The number of rooms or windows
  • The product the joint needs

The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Asking for a quote

When you call or email, these details help:

  • Photos by email, if that’s easy
  • Roughly how big the job is
  • How we’d reach the joints
  • If someone has resealed it before

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.

Signs you need fire rated sealant in Heathfield

Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

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

  • Open gaps behind door architraves
  • Ordinary sealant used where a fire-rated product was needed
  • New service routes left unsealed after building work
  • Cracked or shrunken fire-rated sealant

For buildings such as St Richards Church, gaps around pipes and cables are worth checking after any building work there.

Before booking anyone

  • Whether they seal over old material or remove it
  • What insurance they hold
  • What the cure time is
  • What the quote includes, VAT included or not
