Fire rated sealant for Highleigh homes and businesses

How we handle fire rated sealant in Highleigh

We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. Typical jobs include standard silicone or caulk in a fire-stopping gap and cracked or shrunken fire-rated sealant, on service penetrations, door frames and pipe & cable gaps.

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

There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a small place like Highleigh, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Why us?

  • Arbo and Everbuild products
  • Rated 4.9 stars on Google

Honest limits

Before booking, it’s worth knowing the limits:

  • Openings too large for sealant, which need batts, boards or another system
  • Problems with the door itself rather than the gap around the frame
  • Walls or floors that weren’t built to resist fire

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

Surfaces we seal

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

Commercial buildings in Highleigh

For seaside hotels, guest houses and holiday lets around Highleigh, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. There are hotels and other places to stay in and around Highleigh. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a building such as Sidlesham Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Mary Our Lady Sidlesham are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Different surfaces, different methods

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we will tell you.

Highleigh: your questions answered

Do you work for landlords with property near Chichester station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Do you work for hotels and guest houses in Highleigh?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Can you tell me which gaps need fire stopping?

No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.

How long will you be here?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will say how long yours will take.

Is there any odour?

Some sealants have a smell while they cure. Opening a window helps.

What fire rating will the seal have?

Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

How to look after the new joints

After the cure time, these simple habits help:

  • File the fire-stopping record where your assessor can find it
  • Allow for resealing whenever new services are run
  • Ask every contractor to reseal any fire stopping they disturb
  • Photograph sealed gaps before they’re covered up

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

When to call us in Highleigh

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

People normally contact us after spotting one of these:

  • Ordinary sealant used where a fire-rated product was needed
  • Gaps where walls meet ceilings or slabs
  • Open gaps behind door architraves
  • Damaged fire sealant left by other trades

For landlords with property near Chichester station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What to look for in a quote

  • How long to leave it before use
  • Are they insured?
  • How hidden problems are handled
  • Is the old sealant removed completely?

10 questions to ask before you book

How the visit works

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a small place like Highleigh, access is normally the main thing to plan.
