Fire rated sealant near Walberton

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

How we handle fire rated sealant in Walberton

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on door frames, pipe & cable gaps and service penetrations, and the jobs we see most are gaps around pipes and cables through fire-resisting walls and linear gaps at the head of walls.

In a village or hamlet like Walberton, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. In a small place like Walberton, access is usually 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. 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.

Preparing for the visit

  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about stairs, lifts or work at height

Surface by surface

Flats and HMOs

Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

When something else is needed

Before booking, it’s worth knowing the limits too:

  • Fire doors that need new seals, closers or hardware
  • A wall that isn’t a fire-resisting element to begin with
  • Openings too large for sealant, which need batts, boards or another system

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.

What we seal

  • Plasterboard & masonry
  • Flats & HMOs
  • Pipe & cable gaps

What fire rated sealant looks like in Walberton

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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

Letting a property close to Barnham station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as St Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Walberton and Binsted CofE Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Why act early in Walberton

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Walberton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

  • Working hours on commercial sites

Your questions about fire rated sealant in Walberton

Can you do fire rated sealant in Walberton?

Yes. We work across London and the South East, and Walberton is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Do you work for landlords with property near Barnham station?

Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

Do you seal gaps around fire door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door, its seals and closer are for a door specialist.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Can I use normal mastic around a pipe through a fire wall?

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 tell me which gaps need fire stopping?

No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
