Fire rated sealant near Westbourne

Do you need fire rated sealant in Westbourne?

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

The problems people normally mention when they call include:

  • New service routes left unsealed after building work
  • Open holes round services passing through fire walls
  • Cracked or shrunken fire-rated sealant
  • Gaps where walls meet ceilings or slabs

Schools such as Westbourne Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

How we handle fire rated sealant in Westbourne

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 apply it to the depth its tested detail calls for. We work on plasterboard & masonry, service penetrations and flats & HMOs, and common reasons people get in touch are open holes round services passing through fire walls and open gaps behind door architraves.

For a small place like Westbourne, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

Whatever the size of the job, you get the same 12-month guarantee.

Fire rated sealant in Westbourne: local notes

For seaside hotels, guest houses and holiday lets around Westbourne, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

Community buildings like St John the Baptist's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Emsworth station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Westbourne is about 3 miles east of Havant, in West Sussex. Jobs in Westbourne get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 371 places across West Sussex, large and small. For nearby work, see our Portsmouth page, about 8 miles away.

Landlord and commercial work in Westbourne

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

For anyone letting property in or around Westbourne, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

What sealant work cannot fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • A wall that is not a fire-resisting element to begin with
  • Deciding what fire stopping a building needs
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What we seal

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

The process

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Westbourne, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  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. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Tell us if parking is tricky
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Westbourne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Look in service cupboards and ceiling voids from time to time
  • Allow for resealing whenever new services are run
  • Keep pictures of seals that will be hidden
  • Make resealing part of every contractor’s brief

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Common questions in Westbourne

Do you cover Westbourne for fire rated sealant?

Yes, Westbourne is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

Will you come out to Westbourne?

Yes. Westbourne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

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.

Can new sealant go over the old?

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

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame, and we will mention anything we notice about the door.

How long will you be here?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.
