Fire rated sealant for Petersfield homes and businesses

The process

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Petersfield, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.

  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Tell us about any water getting in
  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children

How we handle fire rated sealant in Petersfield

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on. We work on door frames, flats & HMOs and pipe & cable gaps, and people most often call us about unsealed gaps where pipes and cables go through a wall and standard silicone or caulk in a fire-stopping gap.

For anyone managing a school, care home, pub or office in Petersfield, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Out-of-hours working is possible to arrange.

A one-year guarantee comes as standard.

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Assessing a building’s fire safety
  • Fire doors that need new seals, closers or hardware
  • Construction that doesn’t provide fire resistance on its own

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

Joints and surfaces we work on

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

Workplaces and buildings in Petersfield

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Schools such as Petersfield Infant School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Peter's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How we quote for fire rated sealant

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

  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • How easy the joints are to reach

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.

Helping us quote

When you call or email, these details help:

  • The rough size of the job
  • How we’d reach the joints
  • If someone has resealed it before
  • The problem you’ve noticed

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Why it’s worth doing now in Petersfield

Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Petersfield they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why us?

  • Tidy, careful work
  • Old sealant always removed completely
  • Over 20 years’ experience
  • Sanitary silicone with an anti-fungal additive in wet areas

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Landlord and commercial work in Petersfield

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

When to call us in Petersfield

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

Signs it’s time to call us include:

  • Unsealed gaps around fire door frames
  • Fire seals that have cracked with movement
  • Unsealed gaps where pipes and cables go through a wall
  • Linear gaps at the head of walls

For landlords with property near Petersfield station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

  • Is the old sealant removed completely?
  • How the colour is chosen
