About our fire rated sealant in Headington

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, one gap at a time. We work on service penetrations, linear gaps and plasterboard & masonry, and the jobs we see most are gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed.

Community buildings, schools and small businesses around places like Headington have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. Our tips:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Look in service cupboards and ceiling voids from time to time
  • File the fire-stopping record where your assessor can find it
  • Get damaged fire seals looked at promptly

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

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.

Commercial buildings in Headington

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

Schools such as St Andrew's Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St Andrew's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

FAQs for Headington

Will you come out to Headington?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

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

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

Can I choose the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Are you insured?

Yes. Full insurance covers our work.

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or drop us an email with a short description of the job.

Will it make a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Do you need fire rated sealant in Headington?

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Most people get in touch after spotting something like this:

  • Unsealed gaps where pipes and cables go through a wall
  • Cracked or shrunken fire-rated sealant
  • Door frames with gaps between frame and wall
  • Sealant items on a fire risk assessment action list

Letting a property close to Oxford station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

10 questions to ask before you book

Landlords, agents and businesses in Headington

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Why deal with it now?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Homes in smaller places like Headington can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

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.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

When it is not the sealant

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Openings too large for sealant, which need batts, boards or another system
  • Walls or floors that weren’t built to resist fire
  • Certifying a building or signing off its fire safety

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

What we do, step by step

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. Parking around Headington is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  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.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Mention any tricky access
  • Let us know about parking restrictions
