Signs you need fire rated sealant in Leckhampstead

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

People normally contact us after spotting something like this:

  • Linear gaps at the head of walls
  • Fire seals that have cracked with movement
  • Fire stopping disturbed by later work
  • Sealant items on a fire risk assessment action list

For buildings such as Church of St Mary (Assumption of the Blessed Virgin Mary), older buildings that have had new heating or wiring often have service gaps worth checking.

Our hiring checklist

Fire rated sealant in Leckhampstead, done properly

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate. If you’re dealing with new service routes left unsealed after building work and linear gaps at the head of walls, we can help, on plasterboard & masonry, linear gaps and flats & HMOs alike.

For holiday lets, converted business premises or a community building near Leckhampstead, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

A one-year guarantee comes as standard, so you’re covered after we have gone.

What happens if it’s left?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Around Leckhampstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What fire rated sealant looks like in Leckhampstead

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

In and around Leckhampstead, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

When something else is needed

A few problems are outside what sealant work can do:

  • Big openings where sealant alone is not the tested solution
  • Sign-off of the building, which sits with building control or your assessor
  • Doors that are not fire doors in the first place

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

Leckhampstead: your questions answered

Do you cover smaller places like Leckhampstead?

Yes, Leckhampstead is covered. We work across 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 Leckhampstead?

All our work, in Leckhampstead and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.

Do you work in flats, HMOs and commercial buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.

Are you an approved applicator?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Surface by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement.

The process

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. Somewhere as small as Leckhampstead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  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. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky

Landlord and commercial work in Leckhampstead

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Looking after it afterwards

Aftercare is simple:

  • Keep pictures of seals that will be hidden
  • Do not paint over fire sealant until it has cured
  • Allow for resealing whenever new services are run
  • Include hidden areas like risers in routine checks

Don’t 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.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
