Fire rated sealant in Sheerness

Fire rated sealant in Sheerness, done properly

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. We work on service penetrations, pipe & cable gaps and door frames, and people most often call us about gaps around pipes and cables through fire-resisting walls and standard silicone or caulk in a fire-stopping gap.

Commercial work around a smaller place like Sheerness usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

There’s a 12-month guarantee on every job, whatever its size.

When to call us in Sheerness

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

People normally contact us when they notice one of these:

  • Joints picked up in a fire-stopping survey
  • New service routes left unsealed after building work
  • Open holes round services passing through fire walls
  • Gaps where walls meet ceilings or slabs

Rented homes near Sheerness-On-Sea station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

What your quote should include

  • What happens if they find a problem under the old sealant
  • How long the guarantee is
  • Are they insured?
  • How the colour is chosen

Our hiring checklist

How it works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on how many gaps there are. For a job in Sheerness, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Let us know about parking restrictions
  • Let us know about stairs, lifts or work at height
  • Keep pets and children clear of the area while we work

Keeping the joints in good condition

Simple care keeps the joints in good condition. Our advice:

  • Don’t paint over fire sealant until it has cured
  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors
  • Keep the record of products and locations with your fire safety documents

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.

When it isn’t the sealant

New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:

  • Fire doors that need new seals, closers or hardware
  • Certifying a building or signing off its fire safety
  • Fire risk assessments, which need a qualified assessor

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

What we seal

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

Your questions about fire rated sealant in Sheerness

Do you cover Sheerness for fire rated sealant?

Yes. Our work covers London and the South East, and Sheerness is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Is Sheerness within the area you cover?

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

What does fire rated sealant cost?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

Can you give us a record of the work?

Yes. We record the locations we have sealed and the products used to keep with your fire safety documents.

What information do you need?

A short description and the location, with photos by email if possible. If we need more, we will ask.

Do you remove the old sealant?

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

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.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Around Sheerness, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Why us?

  • Old sealant always removed completely
  • Arbo and Everbuild products
  • We leave the area clean and tidy
  • Anti-fungal silicone where joints get wet

Fire rated sealant around Sheerness

If you run a hotel, guest house or holiday let in a coastal place like Sheerness, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

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

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
