What the job involves on each surface

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.

How we handle fire rated sealant in Blenheim

Bigger jobs can be worked through in stages, flat by flat or floor by floor. It gives you a list to keep with the building’s fire safety documents. We work on plasterboard & masonry, pipe & cable gaps and linear gaps, and common reasons people get in touch are standard silicone or caulk in a fire-stopping gap and new service routes left unsealed after building work.

Work in a small place like Blenheim is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

Each job carries a 12-month guarantee.

What we do, step by step

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. Somewhere as small as Blenheim, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

When it isn’t the sealant

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

  • A wall that is not a fire-resisting element to begin with
  • Problems with the door itself rather than the gap around the frame
  • Deciding what fire stopping a building needs

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

Surfaces we seal

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

Why deal with it now?

Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Around Blenheim, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

What you get with us

  • Neat joints and a tidy finish
  • Sanitary silicone with an anti-fungal additive in wet areas
  • We never seal over old sealant
  • 4.9 on Google from 180+ five-star reviews

Common problems we fix in Blenheim

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.

The problems people usually mention when they call are:

  • Fire stopping disturbed by later work
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps around pipes and cables through fire-resisting walls
  • Cracked or shrunken fire-rated sealant

If you let a flat or house near Radley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Our hiring checklist

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Plan fire stopping into any work that goes through walls or floors
  • Include hidden areas like risers in routine checks
  • File the fire-stopping record where your assessor can find it
  • Take pictures of fire stopping before ceilings or boxing go back

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Fire rated sealant around Blenheim

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 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 Garsington Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
