Fire rated sealant in Cold Brayfield

How we handle fire rated sealant in Cold Brayfield

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. 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. If you have ordinary sealant used where a fire-rated product was needed and new service routes left unsealed after building work, we can put it right.

For a small place like Cold Brayfield, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

Whatever the size of the job, it’s backed by our one-year guarantee in Cold Brayfield and across Milton Keynes.

Looking after it afterwards

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

  • Check risers, ceiling voids and cupboards during building checks
  • Keep the record of products and locations with your fire safety documents
  • Do not paint over fire sealant until it has cured
  • Get damaged fire seals looked at promptly

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

FAQs for Cold Brayfield

Do you cover Cold Brayfield for fire rated sealant?

Yes. We work across London and the South East, and Cold Brayfield is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Is there a guarantee on fire rated sealant in Cold Brayfield?

All our work, in Cold Brayfield and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Where do you work from?

We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.

What information do you need?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do you certify the fire stopping?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.

Do you provide details of the products used?

Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Certifying a building or signing off its fire safety
  • Openings too large for sealant, which need batts, boards or another system
  • Deciding what fire stopping a building needs

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

What we seal

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

How we quote for fire rated sealant

We don’t publish a price list. The quote depends on:

  • When we can work, for business premises
  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

Photos help, but a description is a good start. Please mention:

  • A few pictures by email, if you can
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • The problem you’ve noticed

For fire rated sealant in Cold Brayfield, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you will get a clear quote before any work starts.

Why deal with it now?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Older cottages and farmhouses around Cold Brayfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.

What you get with us

  • Approved under the ARBOMaster scheme
  • We never seal over old sealant
  • Trusted Arbo and Everbuild sealants
  • We leave the area clean and tidy

The process

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. 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 Cold Brayfield, 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. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit
  • Mention any sign-in or site rules at work premises

Advice

Fire rated sealant around Cold Brayfield

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, 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.

Managing a site like Newton Blossomville Church of England School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What the job involves on each surface

Service penetrations

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
