Fire rated sealant in North Chailey

About our fire rated sealant in North Chailey

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, one gap at a time. We work on service penetrations, pipe & cable gaps and plasterboard & masonry, and people most often call us about door frames with gaps between frame and wall and damaged fire sealant left by other trades.

If you have holiday lets, a converted barn used for business or a community building near North Chailey, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Every job is covered by our 12-month guarantee, wherever you are in East Sussex.

How the job changes by surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as North Chailey, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  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. We record the locations and products used for your records.

Preparing for the visit

  • Keep children and pets away from the work area
  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts

Advice

Why act early in North Chailey

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Around North Chailey, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.

Looking after it afterwards

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

  • Store the list of sealed gaps with your building paperwork
  • Do not paint over fire sealant until it has cured
  • Ask every contractor to reseal any fire stopping they disturb
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Your questions about fire rated sealant in North Chailey

Do you work for landlords with property near Plumpton station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Is North Chailey in your area for fire rated sealant?

Yes, North Chailey is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Can you match the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Signs you need fire rated sealant in North Chailey

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

It’s worth asking for a quote if you see:

  • Old fire sealant that has split or come away
  • Gaps around pipes and cables through fire-resisting walls
  • Open gaps behind door architraves
  • Open joints along the top of partitions

Managing a site like Chailey Heritage School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

What to look for in a quote

  • Whether all the old sealant comes out first
  • Which sealant they’ll use, and why
  • Whether you can choose the colour
  • The length of the guarantee

Honest limits

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • Doors that aren’t fire doors in the first place
  • Big openings where sealant alone isn’t the tested solution
  • Assessing a building’s fire safety

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

What we seal

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

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The number and length of the joints
  • Any mould that needs treating
  • Whether the work is at height
  • How many rooms, windows or areas are involved

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Helping us quote

To make quoting easier, please include:

  • Where the property is
  • The rough size of the job
  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height

Every job is quoted individually. Just phone 0345 464 0079 or send us an email with the details.

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
