We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. If you have standard silicone or caulk in a fire-stopping gap and joints picked up in a fire-stopping survey, we can put it right, on flats & HMOs, door frames and pipe & cable gaps alike.

For holiday lets, converted business premises or a community building near Stonegate, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Big or small, it’s backed by our one-year guarantee in Stonegate and across East Sussex.

Why deal with it now?

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. Around Stonegate, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What you get with us

  • Experience in homes, commercial sites and hotels
  • One-year guarantee on every job
  • Trusted Arbo and Everbuild sealants
  • Anti-fungal silicone where joints get wet

Quotes for fire rated sealant in Stonegate

For a quick quote, just ask. What matters most is:

  • Access and height
  • How many areas need sealing
  • When we can work, for business premises
  • Which sealant suits the joint

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What we need to know

When you contact us, these details help:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • The address or postcode of the job

For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.

What we do, step by step

There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. Somewhere as small as Stonegate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we are working on
  • Mention any sign-in or site rules at work premises

Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.

What fire rated sealant looks like in Stonegate

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 work to the specification you’re given, installing the product to its tested details.

If you look after a church, hall or community building such as Church of St Peter, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Stonegate Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

Stonegate is about 9 miles south-east of Royal Tunbridge Wells, in East Sussex.

Surface by surface

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.

What we’re called out for in Stonegate

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.

Any of these means the joints need attention:

  • Open joints along the top of partitions
  • Unsealed gaps around fire door frames
  • Sealant items on a fire risk assessment action list
  • Fire stopping disturbed by later work

For landlords with property near Stonegate station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What sealant work can’t fix

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Fire doors that need new seals, closers or hardware
  • Large holes that need a different fire-stopping system
  • Fire risk assessments, which need a qualified assessor

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Joints and surfaces we work on

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

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
