Trusted fire rated sealant in St Mary Bourne

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

We also work for property managers and facilities teams in St Mary Bourne and across Hampshire. We can quote a run of properties together.

Fire rated sealant in St Mary Bourne

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you’re dealing with sealant items on a fire risk assessment action list and standard silicone or caulk in a fire-stopping gap, we can help.

For holiday lets, converted business premises or a community building near St Mary Bourne, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

All our work comes with a one-year guarantee, wherever you are in Hampshire.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Fire rated sealant around St Mary Bourne

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

For buildings such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as St Mary Bourne Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Do you need fire rated sealant in St Mary Bourne?

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.

These are the problems we are asked about most:

  • New service routes left unsealed after building work
  • Unsealed gaps around fire door frames
  • Linear gaps at the head of walls
  • Gaps flagged on a fire risk assessment

Rented homes near Whitchurch (Hampshire) station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Our hiring checklist

How the visit works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as St Mary Bourne, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

What happens if it’s left?

A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around St Mary Bourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking

Questions from St Mary Bourne

Can you do fire rated sealant in St Mary Bourne?

Yes. We work across London and the South East, and St Mary Bourne is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.

Will you come out to St Mary Bourne?

Yes, St Mary Bourne is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Where do you work from?

We work from Crawley. Our applicators cover St Mary Bourne.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected.

Can ordinary silicone be used in a fire-stopping gap?

No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.

Is the work guaranteed?

Yes. Each job is guaranteed for twelve months.

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Include fire stopping when you schedule refits
  • Store the list of sealed gaps with your building paperwork
  • Photograph sealed gaps before they’re covered up
  • Flag any open gap you spot round a pipe or cable

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we will tell you which one you have.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
