Need fire rated sealant in North Street?

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. Where a wall is exposed, as many are in small places like North Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Why book with us

  • Approved under the ARBOMaster scheme
  • Homes, businesses and hotels
  • Anti-fungal silicone where joints get wet
  • More than 20 years in sealant work

About our fire rated sealant in North Street

Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. Typical jobs include new service routes left unsealed after building work and fire seals that have cracked with movement, across pipe & cable gaps, linear gaps and plasterboard & masonry.

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

You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

What we’re called out for in North Street

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

It’s worth asking for a quote if you see:

  • Ordinary sealant used where a fire-rated product was needed
  • Door frames with gaps between frame and wall
  • Cracked or shrunken fire-rated sealant
  • New service routes left unsealed after building work

Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Choosing a sealant specialist

Workplaces and buildings in North Street

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.

If you look after a building such as Ropley Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

North Street is about 6 miles south-west of Alton, in Hampshire. Our applicators cover fire rated sealant for householders, landlords and businesses in North Street. Our area takes in 683 places across Hampshire, large and small. You can also see our page for Southampton, about 18 miles away.

What affects the quote in North Street

Some jobs are bigger than they look, and some smaller. The main factors:

  • How many rooms, windows or areas are involved
  • Whether there’s mould to deal with
  • Any working-time requirements on site
  • Which sealant suits the joint

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What to tell us for a quote

To make quoting easier, please include:

  • The address or postcode of the job
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • What’s wrong with the joints now

Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.

North Street questions

What guarantee comes with fire rated sealant in North Street?

All our work, in North Street and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Will you come out to North Street?

Yes, North Street is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Will you assess my building’s fire safety?

No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Do you have insurance?

Yes. Full insurance covers our work.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we will quote it together.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status.

How long will you be here?

It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.

How to look after the new joints

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

  • Include fire stopping when you schedule refits
  • Ask every contractor to reseal any fire stopping they disturb
  • Photograph sealed gaps before they’re covered up
  • Flag any open gap you spot round a pipe or cable

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.

Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What we do, step by step

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like North Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

How to prepare

  • Keep pets and children clear of the area while we work
  • Move anything stored near the joints
  • Mention any sign-in or site rules at work premises

When something else is needed

It helps to know what we cannot do too:

  • Openings too large for sealant, which need batts, boards or another system
  • Certifying a building or signing off its fire safety
  • Construction that doesn’t provide fire resistance on its own

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
