Fire rated sealant for Shalstone homes and businesses

What happens on the day

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In a small place like Shalstone, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  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. We record the locations and products used for your records.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky
  • Let us know about stairs, lifts or work at height

Fire rated sealant in Shalstone

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 are dealing with ordinary sealant used where a fire-rated product was needed and seals cut through by electricians, plumbers or data installers, we can help, on plasterboard & masonry, pipe & cable gaps and service penetrations alike.

In a village or hamlet like Shalstone, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

All our work is covered by a 12-month guarantee.

Surface by surface

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Include fire stopping when you schedule refits
  • Check risers, ceiling voids and cupboards during building checks
  • Tell trades working in the building that fire seals must be put back

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 and the list grows.

Commercial buildings in Shalstone

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For buildings such as Church of St Edward, service openings in its walls need the right fire-rated sealant, as in any building. In and around Shalstone, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Quotes for fire rated sealant in Shalstone

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

  • Any working-time requirements on site
  • The amount of work
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • A few pictures by email, if you can
  • The rough size of the job
  • If it’s domestic, commercial or a hotel
  • What’s wrong with the joints now

If you’re in Shalstone and need fire rated sealant, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before work begins.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Doors that are not fire doors in the first place
  • Construction that does not provide fire resistance on its own
  • Openings too large for sealant, which need batts, boards or another system

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Joints and surfaces we work on

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

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Questions from Shalstone

Will you come out to Shalstone?

Yes, Shalstone is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is fire rated sealant in Shalstone guaranteed?

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

What does fire rated sealant cost?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

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

No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

What should I tell you?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Why deal with it now?

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, 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 Shalstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
