Fire rated sealant in Arborfield

Fire rated sealant in Arborfield

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We’re often asked to deal with new service routes left unsealed after building work and damaged fire sealant left by other trades, across plasterboard & masonry, pipe & cable gaps and service penetrations.

For holiday lets, converted business premises or a community building near Arborfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Our work is backed for twelve months.

What happens if it’s left?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Older cottages and farmhouses around Arborfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Arborfield questions

Is Arborfield in your area for fire rated sealant?

Yes. We work across London and the South East, and Arborfield is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Winnersh station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

Are you fully insured?

Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Is it OK to seal over old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Where are you based?

Our base is Crawley. We work across South East England, London and Scotland.

For landlords and businesses

For anyone letting property in or around Arborfield, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.

Landlords and letting agents in Arborfield can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Ask which product was used before you paint
  • Flag any open gap you spot round a pipe or cable
  • Plan fire stopping into any work that goes through walls or floors
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

How it works

Before we leave, we go over the finished joints with you. The visit itself usually takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. In a small place like Arborfield, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Keep children and pets away from the work area
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

Commercial buildings in Arborfield

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

If you let a flat or house near Winnersh station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of St Bartholomew are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Arborfield is about 3 miles west of Wokingham, in Reading. Whether you are in the middle of Arborfield or further out, we cover fire rated sealant for every kind of property, from flats and houses to offices and hotels. We cover 34 towns and villages across Reading, from the larger towns to small villages.

Work in RG2 works the same way as everywhere else we cover. If you need fire rated sealant at a property on Church Lane, Walden Avenue and Cartershill Lane or anywhere close by, we can help. Neighbouring places we cover for fire rated sealant include Shinfield (2 miles west), Lower Earley (2 miles north), Ryeish Green (2 miles west), Earley (2 miles north) and Whitley Wood (2 miles north-west). We also work in nearby towns such as Caversham (6 miles north-west), Norcot (6 miles north-west), West Reading (5 miles north-west), Tilehurst Within (6 miles north-west), Caversham Heights (6 miles north-west) and Horncastle (6 miles north-west).

Surface by surface

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.

What we are called out for in Arborfield

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

These are the problems we’re asked about most:

  • Gaps flagged on a fire risk assessment
  • Seals cut through by electricians, plumbers or data installers
  • Open holes round services passing through fire walls
  • Open joints along the top of partitions

Managing a site like The Coombes Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
