Need fire rated sealant in Shelley?

Fire rated sealant for homes and businesses in Shelley

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We’re often asked to deal with new service routes left unsealed after building work and fire seals that have cracked with movement, across service penetrations, flats & HMOs and door frames.

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

A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What we can’t put right

We’d rather tell you now than do work that won’t last, so these are the limits:

  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Where we work in Shelley

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

Surface by surface

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.

Workplaces and buildings in Shelley

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.

Schools such as Ongar Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.

Why deal with it now?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a small place like Shelley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Shelley: your questions answered

Do you cover Shelley for fire rated sealant?

Yes. We work across London and the South East, and Shelley is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

Is Shelley within the area you cover?

Yes, Shelley is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Where do you work from?

Our base is Crawley. Our area covers South East England, London and Scotland.

How long does the job take?

That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Do you certify the fire stopping?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Landlords, agents and businesses in Shelley

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

Landlords and agents in Shelley can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Should I try it myself first?

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 are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We look at:

  • Access and height
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • Any mould that needs treating

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Helping us quote

When you contact us, it’s useful to know:

  • Access, such as stairs, a lift or height
  • Where the property is
  • How many joints, rooms or windows are involved
  • Photos by email, if that is easy

We don’t publish a price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.

What we do, step by step

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Shelley, 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. Access to each area is agreed so the work can run in order.
  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.

Preparing for the visit

  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks
  • On commercial sites, let us know about site rules
