Fire rated sealant near Great Missenden

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Fire rated sealant in Great Missenden, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on plasterboard & masonry, linear gaps and service penetrations, and common reasons people get in touch are holes left by a change of layout and damaged fire sealant left by other trades.

In a village or hamlet like Great Missenden, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.

Fire rated sealant around Great Missenden

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’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Great Missenden CofE Combined 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 Saints Peter and Paul, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Great Missenden station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Why it’s worth doing now in Great Missenden

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Great Missenden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Why book with us

  • We never seal over old sealant

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Keep the record of products and locations with your fire safety documents
  • Keep pictures of seals that will be hidden
  • Allow for resealing whenever new services are run
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
