Looking after it afterwards

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

  • Get damaged fire seals looked at promptly
  • Make resealing part of every contractor’s brief
  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks

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. Have it sealed, then keep the record.

About our fire rated sealant in Denton

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 the sealant goes in to the depth the product’s details set. If you are dealing with sealant items on a fire risk assessment action list and linear gaps at the head of walls, we can put it right, on linear gaps, flats & HMOs and door frames alike.

Work in a small place like Denton is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

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

How the job changes by surface

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we’ll tell you.

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.

What happens on the day

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Denton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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 gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Advice

Workplaces and buildings in Denton

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as Garsington Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Radley station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Church of All Saints, gaps around pipes and cables are worth checking after any building work there.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Why act early in Denton

For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Where a wall is exposed, as many are in small places like Denton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
