About our fire rated sealant in Rotherbridge

We often work from an action list drawn up by a fire risk assessor on buildings across Rotherbridge. If you share the list, we can quote for the gaps that need fire-rated sealant. Common call-outs are for gaps where walls meet ceilings or slabs and cracked or shrunken fire-rated sealant, across flats & HMOs, linear gaps and service penetrations.

In a village or hamlet like Rotherbridge, 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.

Each job carries a 12-month guarantee, whatever its size.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Rotherbridge, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in

When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Construction that does not provide fire resistance on its own
  • Fire risk assessments, which need a qualified assessor
  • Issuing a fire rating or certificate for a building

If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

Joints and surfaces we work on

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

Workplaces and buildings in Rotherbridge

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.

Schools such as Petworth Cof E Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like The Parish Church of All Hallows are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you do try it yourself, take your time over the 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.

What affects the cost of fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The old material and how stubborn it is
  • The type of sealant required
  • The size of the job
  • Any working-time requirements on site

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

What we need to know

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Roughly how big the job is
  • If someone has resealed it before
  • The type of property
  • Where the job is, and your postcode

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.

What the job involves on each surface

Door frames

Frame gaps are normally hidden behind the architrave. We seal any open gap to the product’s tested details.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

Landlord and commercial work in Rotherbridge

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Common problems we fix in Rotherbridge

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

These are the problems we are asked about most:

  • Unsealed gaps around fire door frames
  • Joints picked up in a fire-stopping survey
  • Fire stopping disturbed by later work
  • Linear gaps at the head of walls

Letting a property close to Pulborough station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
