What we can’t put right

We will always be straight with you, so here’s what new sealant will not do:

  • Sign-off of the building, which sits with building control or your assessor
  • Doors that are not fire doors in the first place
  • Deciding what fire stopping a building needs

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

Surfaces we seal

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

Fire rated sealant in North Aston

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, gap by gap. If you have gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap, we can put it right.

Somewhere as small as North Aston, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

There’s a 12-month guarantee on every job.

What fire rated sealant looks like in North Aston

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 work to the specification you are given, installing the product to its tested details.

If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

How we quote for fire rated sealant

We quote each job individually. These are the things that affect it:

  • Whether old sealant or filler has to be cut out
  • The size of the job
  • Whether there’s mould to deal with
  • Working hours on commercial sites

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • The rough size of the job
  • Pictures of the joints, sent by email
  • If someone has resealed it before
  • Where the job is, and your postcode

We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job.

Signs you need fire rated sealant in North Aston

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.

Keep an eye out for these signs:

  • Damaged fire sealant left by other trades
  • Fire seals that have cracked with movement
  • Sealant items on a fire risk assessment action list
  • Door frames with gaps between frame and wall

Rented homes near Heyford station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • How the joint is cleaned and prepared
  • Whether VAT is included
  • What guarantee comes with the work
  • How the colour is chosen

Common questions in North Aston

Is North Aston in your area for fire rated sealant?

Yes, North Aston is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.

Do you work for landlords with property near Heyford station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.

What does intumescent mean?

An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Do you work in flats, HMOs and commercial buildings?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

Will you leave a mess?

We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

If you manage several properties in or around North Aston, several properties can go on one quote. Send us the addresses and the work at each.

Keeping the joints in good condition

So the new joints stay in good condition:

  • File the fire-stopping record where your assessor can find it
  • Get damaged fire seals looked at promptly
  • Ask which product was used before you paint
  • Keep general-purpose foam and caulk away from fire-stopping gaps

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.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. In a small place like North Aston, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. 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

  • Tell us about any water getting in
  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height

Advice

Different surfaces, different methods

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Flats and HMOs

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