Fire rated sealant in South Stoke, 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. If you are dealing with gaps left after a refit or conversion and linear gaps at the head of walls, we can put it right, whatever the surface.

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

A 12-month guarantee comes with the work, just as it does everywhere we cover.

How we quote for fire rated sealant

The quote reflects the job in front of us. We take into account:

  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • The number and length of the joints
  • Which sealant suits the joint

What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What to tell us for a quote

When you contact us, it’s useful to know:

  • Any access issues, like height or stairs
  • Roughly how big the job is
  • Any previous sealing or DIY work
  • What’s wrong with the joints now

Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job and send pictures if you have them.

What happens if it’s left?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Around South Stoke, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What you get with us

  • Homes, businesses and hotels
  • Sanitary silicone with an anti-fungal additive in wet areas
  • A 12-month guarantee on all work

Commercial buildings in South Stoke

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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.

Managing a site like South Stoke Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of St Andrew, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Cholsey station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

When it is not the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Large holes that need a different fire-stopping system
  • Problems with the door itself rather than the gap around the frame
  • Certifying a building or signing off its fire safety

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Joints and surfaces we work on

  • Door frames
  • Pipe & cable gaps
  • Service penetrations
  • Linear gaps
  • Plasterboard & masonry
  • Flats & HMOs

What happens on the day

Before we leave, we go over the finished joints with you and explain the cure time. 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 amount of work. For a village or hamlet like South Stoke, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Move anything stored near the joints
  • Keep children and pets away from the work area
  • Tell us if parking is tricky

Advice

What the job involves on each surface

Flats and HMOs

Working in occupied flats needs some planning. We agree access to each flat and the common parts before work begins.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

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. Everything old must be removed first.

South Stoke questions

Can you do fire rated sealant in South Stoke?

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

I let a flat near Cholsey station. Can you help?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can you fill the gap behind a fire door frame?

Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door, its seals and closer are for a door specialist.

Not at all. The area is protected while we work and cleaned up afterwards.

Where do you work from?

We work from Crawley. We cover South Stoke and the rest of Oxfordshire.

Can you match the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator.
