Fire rated sealant in Horseport, done properly

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Common call-outs are for door frames with gaps between frame and wall and seals cut through by electricians, plumbers or data installers, on plasterboard & masonry, linear gaps and service penetrations.

In a village or hamlet like Horseport, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Landlord and commercial work in Horseport

For anyone letting property in or around Horseport, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Common problems we fix in Horseport

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Any of these means the joints need attention:

  • Linear gaps at the head of walls
  • Sealant items on a fire risk assessment action list
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that isn’t fire-rated

If you look after a church, hall or community building such as St Mary's Church, service openings in its walls need the right fire-rated sealant, as in any building.

How the visit works

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. For a village or hamlet like Horseport, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints

Ask for a quote

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.

Related advice

What happens if it’s left?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Older cottages and farmhouses around Horseport can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Fire rated sealant around Horseport

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.

If you look after a building such as Fordingbridge Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What the job involves on each surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
