How we handle fire rated sealant in Four Ashes

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. If you are dealing with standard silicone or caulk in a fire-stopping gap and door frames with gaps between frame and wall, we can help, whatever the surface.

Somewhere as small as Four Ashes, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Fire rated sealant around Four Ashes

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 work to the specification you are given, installing the product to its tested details.

Schools such as Great Kingshill Church of England Combined School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as St Michael and All Angels Church, gaps around pipes and cables are worth checking after any building work there.

Surface by surface

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment, flat by flat if needed.

DIY sealant or a professional job?

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

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What affects the quote in Four Ashes

Every job gets its own quote. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • The amount of work
  • Any working-time requirements on site

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • If someone has resealed it before
  • How many joints, rooms or windows are involved
  • How we’d reach the joints
  • A few photos by email, if you can

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

What happens if it’s left?

Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a small place like Four Ashes, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • We never seal over old sealant
  • Quality sealants from Arbo and Everbuild
  • Over 20 years’ experience

What happens on the day

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Somewhere as small as Four Ashes, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Keep children and pets away from the work area
  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in

Signs you need fire rated sealant in Four Ashes

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Look out for these signs:

  • Door frames with gaps between frame and wall
  • Open holes round services passing through fire walls
  • Cracked or shrunken fire-rated sealant
  • Linear gaps at the head of walls

Letting a property close to High Wycombe station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
