Workplaces and buildings in Southbourne

For seaside hotels, guest houses and holiday lets around Southbourne, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

If you look after a church, hall or community building such as St. John's, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Southbourne Junior School, fire-stopping around service openings should be restored whenever new services go in.

How we handle fire rated sealant in Southbourne

We often work from an action list drawn up by a fire risk assessor for buildings in Southbourne. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on linear gaps, service penetrations and door frames, and the jobs we see most are gaps where walls meet ceilings or slabs and holes left by a change of layout.

In a smaller place like Southbourne, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.

Our work is backed for twelve months.

Common problems we fix in Southbourne

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.

Most people get in touch when they notice one of these:

  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that isn’t fire-rated
  • Open joints along the top of partitions
  • Fire seals that have cracked with movement

Letting a property close to Southbourne station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before booking

  • How long to leave it before use
  • How the colour is chosen
  • Is VAT in the price?
  • Is the old sealant removed completely?

What happens if it’s left?

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. In an older home around Southbourne, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What you get with us

  • Over 20 years’ experience
  • Full insurance on every job
  • Old sealant always removed completely
  • We leave the area clean and tidy

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you seal gaps around fire door frames?

As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we will tell you how long to expect.

For anyone letting property in or around Southbourne, jobs at different addresses can be quoted together. Send us the addresses and the work at each.

Landlords and letting agents in Southbourne can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Check whether a sealant can be painted before decorating over it
  • Look in service cupboards and ceiling voids from time to time
  • Ask every contractor to reseal any fire stopping they disturb
  • Get damaged fire seals looked at promptly

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

The process

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a handful of gaps, and longer for a whole building. Parking around Southbourne is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  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 and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children

Related advice

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. 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.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

  • Whether it has been sealed before
