About our fire rated sealant in Northway

We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on linear gaps, flats & HMOs and service penetrations, and people most often call us about seals cut through by electricians, plumbers or data installers and standard silicone or caulk in a fire-stopping gap.

If you run a pub, café, guest house or shop in or near Northway, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Workplaces and buildings in Northway

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.

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. If you look after a church, hall or community building such as St Anthony of Padua, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as New Marston Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Northway is about 1 mile north of Oxford, in Oxfordshire. From the centre of Northway to the outskirts, we cover fire rated sealant for every kind of property, from flats and houses to offices and hotels. Our Oxfordshire coverage runs to 443 places, and Northway is one of them.

Postcode districts we cover here for fire rated sealant: OX3. We cover properties on Copse Lane, Marsh Lane and Upway Road and the roads around them. You’ll find Northway on the A40, so it’s easy for us to get to. Neighbouring places we cover for fire rated sealant include Headington (1 mile south-east), Marston (1 mile north-west), New Marston (1 mile south-west), Headington Hill (1 mile south) and Headington Quarry (1 mile south-east). Larger places within reach include Didcot (11 miles south), Bicester (9 miles north), Abingdon-on-Thames (7 miles south), Witney (12 miles west), Thame (11 miles east) and Wantage (15 miles south-west).

Aftercare tips

To keep the joints looking good and working properly:

  • Do not paint over fire sealant until it has cured
  • Flag any open gap you spot round a pipe or cable
  • Keep photos of seals that will be hidden
  • Check risers, ceiling voids and cupboards during building checks

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.

Honest limits

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

  • Walls or floors that weren’t built to resist fire
  • Openings too large for sealant, which need batts, boards or another system
  • Fire doors that need new seals, closers or hardware

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

What affects the cost of fire rated sealant

Your quote is based on your job. We look at:

  • The amount of work
  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is
  • Whether there’s mould to deal with

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • The type of property
  • Where the property is
  • Pictures of the joints, sent by email
  • The rough size of the job

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work.

How it works

You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Parking around Northway 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 plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about parking restrictions

Surface by surface

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth with backing where the detail needs it.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

For landlords and businesses

For anyone letting property in or around Northway, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Northway questions

Is Northway in your area for fire rated sealant?

Yes. We work across London and the South East, and Northway is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Will you come out to Northway?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Do you offer different sealant colours?

Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator.

DIY versus a professional 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.

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.
