What the job involves on each surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.

Fire rated sealant for homes and businesses in Culverstone Green

We often work from an action list drawn up by a fire risk assessor for buildings in Culverstone Green. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on linear gaps, door frames and pipe & cable gaps, and common reasons people get in touch are ordinary sealant used where a fire-rated product was needed and gaps left after a refit or conversion.

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

All of our work is guaranteed for twelve months, in Culverstone Green and everywhere else we cover.

Aftercare tips

After the cure time, these simple habits help:

  • Store the list of sealed gaps with your building paperwork
  • Check risers, ceiling voids and cupboards during building checks
  • Do not paint over fire sealant until it has cured
  • Include fire stopping when you schedule refits

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

What happens if it’s left?

A quick fill with any sealant to hand isn’t 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. Older cottages and farmhouses around Culverstone Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

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

When something else is needed

To be straight with you, some problems need a different trade:

  • Construction that does not provide fire resistance on its own
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone isn’t the tested solution

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

What happens on the day

You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Somewhere like Culverstone Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules

Culverstone Green questions

Can you do fire rated sealant in Culverstone Green?

Yes. Our work covers London and the South East, and Culverstone Green is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Sole Street station?

Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Do you provide details of the products used?

Yes. We record the locations we have sealed and the products used to keep with your fire safety documents.

Can you tell me how many minutes the seal will last?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Can new sealant go over the old?

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.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.

Common problems we fix in Culverstone Green

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Any of these means the joints need attention:

  • Old fire sealant that has split or come away
  • Damaged fire sealant left by other trades
  • Unsealed gaps where pipes and cables go through a wall
  • Ordinary sealant used where a fire-rated product was needed

For site and facilities teams at buildings such as Culverstone Green Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Before booking anyone

  • Who does the work, and how experienced they are
  • What happens if they find a problem under the old sealant
  • How the surfaces are prepared before sealing
  • What insurance they hold

Choosing a sealant specialist

Commercial buildings in Culverstone Green

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Sole Street station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
