Fire rated sealant in Coneyhurst

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you’re dealing with gaps flagged on a fire risk assessment and linear gaps at the head of walls, we can help, whatever the surface.

In a village or hamlet like Coneyhurst, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

Whatever the size of the job, it’s backed by our 12-month guarantee in Coneyhurst and across West Sussex.

Do you need fire rated sealant in Coneyhurst?

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

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

  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers
  • Open holes round services passing through fire walls
  • Gaps flagged on a fire risk assessment

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

What to look for in a quote

  • Whether all the old sealant comes out first
  • Are they insured?
  • Is VAT in the price?
  • When the joint can take water or movement

How to choose a mastic man

What the job involves on each surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance.

Landlords, agents and businesses in Coneyhurst

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.

How it works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Coneyhurst, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules
  • Keep children and pets away from the work area

DIY versus a professional finish

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Fire rated sealant around Coneyhurst

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’re given, installing the product to its tested details.

Schools such as The Weald School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How we quote for fire rated sealant

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

  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • The type of sealant required
  • Whether the work is at height

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.

Asking for a quote

To make quoting easier, let us know:

  • A few pictures by email, if you can
  • If someone has resealed it before
  • What’s wrong with the joints now
  • The rough size of the job

We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

What happens if it’s left?

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Coneyhurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

What you get with us

  • Full insurance on every job
  • Approved under the ARBOMaster scheme
  • Every job guaranteed for a year
  • Arbo and Everbuild products

Common questions in Coneyhurst

Can you work in occupied 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 will plan around it.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Do you provide details of the products used?

Yes. We note each location and the product that went in, so you have it on file.

What fire rating will the seal have?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.

Do you have insurance?

Yes, we are fully insured for domestic and commercial work.
