Fire rated sealant in Aspley Guise, done properly

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on. Typical jobs include gaps flagged on a fire risk assessment and standard silicone or caulk in a fire-stopping gap, across linear gaps, flats & HMOs and service penetrations.

For a small place like Aspley Guise, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

There’s a 12-month guarantee on every job, large or small.

What we’re called out for in Aspley Guise

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

Any of these means the joints need attention:

  • Open holes round services passing through fire walls
  • Cracked or shrunken fire-rated sealant
  • Ordinary sealant used where a fire-rated product was needed
  • Holes left by a change of layout

Letting a property close to Aspley Guise station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • Whether all the old sealant comes out first
  • What happens if they find a problem under the old sealant
  • Whether you can choose the colour
  • What insurance they hold

Our hiring checklist

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check whether a sealant can be painted before decorating over it
  • Keep the record of products and locations with your fire safety documents
  • Never patch a fire seal with standard sealant
  • Get damaged fire seals looked at promptly

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

What fire rated sealant looks like in Aspley Guise

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.

For site and facilities teams at buildings such as Aspley Guise Lower School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Botolph, service openings in its walls need the right fire-rated sealant, as in any building.

Why act early in Aspley Guise

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 sealing itself is often a contained piece of work. Older cottages and farmhouses around Aspley Guise can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Honest limits

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Construction that doesn’t provide fire resistance on its own
  • Doors that aren’t fire doors in the first place
  • Certifying a building or signing off its fire safety

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
