We work on flats & HMOs, service penetrations and pipe & cable gaps, and common reasons people get in touch are open joints along the top of partitions and gaps flagged on a fire risk assessment.

What fire rated sealant looks like in Ashampstead 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.

Community buildings like Church of St Clement are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Goring & Streatley station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

How the job changes by surface

Flats and HMOs

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance to keep disruption down.

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Get damaged fire seals looked at promptly
  • Store the list of sealed gaps with your building paperwork
  • Plan fire stopping into any work that goes through walls or floors
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

When something else is needed

We will always be straight with you, so here’s what sealant cannot fix:

  • Certifying a building or signing off its fire safety
  • Assessing a building’s fire safety
  • Problems with the door itself rather than the gap around the frame

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

What happens on the day

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Ashampstead Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  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.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Clear items away from the joints we are working on
