Trusted fire rated sealant in Headington Quarry

Why deal with it now?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. Around Headington Quarry, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Why us?

  • Full insurance on every job
  • Anti-fungal silicone where joints get wet
  • Neat joints and a tidy finish
  • One-year guarantee on every job

Fire rated sealant for homes and businesses in Headington Quarry

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have standard silicone or caulk in a fire-stopping gap and joints picked up in a fire-stopping survey, we can help.

For a pub, café, guest house or shop in or near Headington Quarry, its washrooms and kitchen need the same sealant care as any big building.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What fire rated sealant looks like in Headington Quarry

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.

If you look after a building such as Headington Quarry Foundation Stage School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Holy Trinity Church, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Oxford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for Headington Quarry

Do you work for landlords with property near Oxford station?

Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Do you cover Headington Quarry for fire rated sealant?

Yes. Our work covers London and the South East, and Headington Quarry is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.

Can new sealant go over the old?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Do you have insurance?

Yes, we are fully insured.

Do the sealants smell?

There can be a smell while the sealant cures. Opening a window helps.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Take photos of fire stopping before ceilings or boxing go back
  • Never patch a fire seal with standard sealant
  • Look in service cupboards and ceiling voids from time to time
  • Flag any open gap you spot round a pipe or cable

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

How the visit works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. A visit to Headington Quarry is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  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. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints

The quote reflects the job in front of us. We look at:

  • Any working-time requirements on site

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.
