How we handle fire rated sealant in Goose Green

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with unsealed gaps around fire door frames and fire seals that have cracked with movement, we can help, on pipe & cable gaps, flats & HMOs and service penetrations alike.

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

Every job is covered by a 12-month guarantee.

What we’re called out for in Goose Green

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.

People generally contact us after spotting one of these:

  • Seals cut through by electricians, plumbers or data installers
  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps around fire door frames
  • Joints picked up in a fire-stopping survey

If you look after a building such as Westfield Community Primary School, fire-stopping around service openings should be restored whenever new services go in.

Choosing a sealant specialist

Landlords, agents and businesses in Goose Green

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.

What happens if it’s left?

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. In a small place like Goose Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Fire rated sealant around Goose Green

What the job involves on each surface

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

FAQs for Goose Green

I let a flat near Broxbourne station. Can you help?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Do you cover smaller places like Goose Green?

Yes, Goose Green is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Are you insured?

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Do you remove the old sealant?

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

Where are you based?

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

What we do, step by step

Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Goose Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  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.

How to prepare

  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts
  • Let us know if you’ve seen damp or leaks

Getting a quote

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

Related advice

Can I do it myself?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the quote in Goose Green

Your quote is based on your job. We look at:

  • The old material and how stubborn it is
  • How much there is to do
  • The number of rooms or windows
  • Any working-time requirements on site

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • The problem you’ve noticed
  • Photos by email, if that is easy
  • If someone has resealed it before
  • Access, such as stairs, a lift or height
