Fire rated sealant in Great Haseley, done properly

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, gap by gap. Typical jobs include gaps flagged on a fire risk assessment and gaps around pipes and cables through fire-resisting walls, on flats & HMOs, linear gaps and pipe & cable gaps.

If you have holiday lets, a converted barn used for business or a community building near Great Haseley, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

A 12-month guarantee comes as standard.

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks
  • Make resealing part of every contractor’s brief
  • Keep photos of seals that will be hidden

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

How it works

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Great Haseley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

How to prepare

  • Mention any tricky access
  • On commercial sites, let us know about site rules
  • Let us know about earlier repairs to the joints

Questions from Great Haseley

Is Great Haseley within the area you cover?

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

Can you do fire rated sealant in Great Haseley?

Yes. Our work covers London and the South East, and Great Haseley is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

What does fire rated sealant cost?

It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.

What does intumescent mean?

Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

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

No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed and we can apply it for you.

Can you seal over the old sealant?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

When something else is needed

A few problems are outside what sealant work can do:

  • Problems with the door itself rather than the gap around the frame
  • Fire risk assessments, which need a qualified assessor
  • Big openings where sealant alone is not the tested solution

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

Where we work in Great Haseley

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

Can I do it myself?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

What affects the quote in Great Haseley

There’s no set price list. What we look at:

  • The type of sealant required
  • Any working-time requirements on site
  • The number and length of the joints
  • Any mould that needs treating

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What we need to know

You don’t need to know the technical terms. It helps if you can tell us:

  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • Roughly how big the job is
  • Whether it has been sealed before

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Surface by surface

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.

Workplaces and buildings in Great Haseley

Great Haseley has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For site and facilities teams at buildings such as Great Milton Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Why it’s worth doing now in Great Haseley

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Older cottages and farmhouses around Great Haseley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
