Fire rated sealant in South Harewood

When to call us in South Harewood

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

Keep an eye out for any of the following:

  • Cracked or shrunken fire-rated sealant
  • Linear gaps at the head of walls
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps flagged on a fire risk assessment

Schools such as Wherwell Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

What to look for in a quote

  • How much experience the applicator has
  • The length of the guarantee
  • Whether all the old sealant comes out first
  • Are they insured?

Choosing a sealant specialist

Fire rated sealant in South Harewood

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. Common call-outs are for holes left by a change of layout and open gaps behind door architraves, on pipe & cable gaps, linear gaps and door frames.

For a small place like South Harewood, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

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

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Keep photos of seals that will be hidden
  • Do not paint over fire sealant until it has cured
  • Keep the record of products and locations with your fire safety documents
  • Make resealing part of every contractor’s brief

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 generally a straightforward job.

Questions from South Harewood

Is South Harewood within the area you cover?

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 Andover station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

What does intumescent mean?

Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Do you take on fire stopping in schools and offices?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.

Do you certify the fire stopping?

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.

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in so it’s there for the next inspection.

How the job changes by surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Why it’s worth doing now in South Harewood

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Where a wall is exposed, as many are in small places like South Harewood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Why us?

  • Trusted Arbo and Everbuild sealants
  • Any old sealant cut out fully, not covered over
  • We are fully insured
  • 4.9 on Google from 180+ five-star reviews
