About our fire rated sealant in Southrope

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’s the part we focus on. Typical jobs include damaged fire sealant left by other trades and unsealed gaps around fire door frames, across plasterboard & masonry, flats & HMOs and door frames.

If you have holiday lets, a converted barn used for business or a community building near Southrope, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

All our work is covered by a one-year guarantee, wherever you are in Hampshire.

Fire rated sealant around Southrope

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.

Rented homes near Alton station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Honest limits

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

  • Problems with the door itself rather than the gap around the frame
  • Large holes that need a different fire-stopping system
  • Walls or floors that weren’t built to resist fire

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

Joints and surfaces we work on

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

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 work involved is often modest. Older cottages and farmhouses around Southrope can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Why book with us

  • Fully insured
  • Anti-fungal sanitary silicone in wet areas

Quotes for fire rated sealant in Southrope

Your quote is based on your job. We look at:

  • The size of the job
  • Whether old sealant or filler has to be cut out
  • Which sealant suits the joint
  • How many rooms, windows or areas are involved

Rather than a set price list, 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.

What we need to know

When you call or email, these details help:

  • Any previous sealing or DIY work
  • A few pictures by email, if you can
  • Where the property is
  • Any access issues, like height or stairs

Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or email us with the details.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Signs you need fire rated sealant in Southrope

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’re asked about most:

  • Gaps filled with a product that is not fire-rated
  • Linear gaps at the head of walls
  • Unsealed gaps around fire door frames
  • New service routes left unsealed after building work

For buildings such as Church of St. Mary, gaps around pipes and cables are worth checking after any building work there.

  • What insurance they hold
  • Whether you can choose the colour
  • What guarantee comes with the work

Our hiring checklist

How the visit works

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Southrope, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any parking rules near the property

How to look after the new joints

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

  • Tell trades working in the building that fire seals must be put back
  • Include hidden areas like risers in routine checks
  • Store the list of sealed gaps with your building paperwork
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
