Fire rated sealant in Gillingham: local notes

For seaside hotels, guest houses and holiday lets around Gillingham, 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. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For landlords with property near Gillingham (Kent) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as Featherby Junior School, service openings in fire-resisting walls need checking after any refurbishment.

Fire rated sealant for homes and businesses in Gillingham

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you are dealing with old fire sealant that has split or come away and fire stopping disturbed by later work, we can put it right.

Hotels and other accommodation in Gillingham need sealant work done around guests. Room-by-room programmes and out-of-hours working can be arranged.

A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Questions from Gillingham

Do you cover Gillingham for fire rated sealant?

Yes. We work across London and the South East, and Gillingham is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.

Is fire rated sealant in Gillingham guaranteed?

All our work, in Gillingham and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Will we have a record of what was sealed?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

Can ordinary silicone be used in a fire-stopping gap?

No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

Will you leave a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Is intumescent sealant the same as fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

Common problems we fix in Gillingham

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps flagged on a fire risk assessment
  • Seals cut through by electricians, plumbers or data installers
  • Holes left by a change of layout
  • Fire seals that have cracked with movement

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

What your quote should include

  • How the colour is chosen
  • How long the guarantee is
  • Whether they’re fully insured
  • How the joint is cleaned and prepared

10 questions to ask before you book

What affects the cost of fire rated sealant

There’s no set price list. What we look at:

  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove

How the job changes by surface

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we will flag it.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

The process

We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. In Gillingham, we work in everything from flats and family homes to offices and hotels. Whichever it is, tell us how to get in, where to park and where the work is.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  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.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

Related advice

Leave it or put it right?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. In a large rental market like Gillingham, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
