What fire rated sealant looks like in St Lawrence Bay

For seaside hotels, guest houses and holiday lets around St Lawrence Bay, 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, 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 St Lawrence Church Centre, gaps around pipes and cables are worth checking after any building work there.

Fire rated sealant in St Lawrence Bay

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. Typical jobs include gaps filled with a product that isn’t fire-rated and unsealed gaps around fire door frames, on service penetrations, pipe & cable gaps and linear gaps.

In a village or hamlet like St Lawrence Bay, 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.

A 12-month guarantee comes as standard.

How we quote for fire rated sealant

There’s no set price list, because no two jobs are the same. The quote depends on:

  • The type of sealant required
  • Whether there’s mould to deal with
  • Whether the work is at height
  • The number of rooms or windows

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Asking for a quote

To help us quote quickly, let us know:

  • Whether it has been sealed before
  • The problem you’ve noticed
  • Any access issues, like height or stairs
  • Photos by email, if that’s easy

For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear quote before any work starts.

Why it’s worth doing now in St Lawrence Bay

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. In a small place like St Lawrence Bay, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Landlord and commercial work in St Lawrence Bay

We also work for property managers and facilities teams. We can quote a run of properties together.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

What we do, step by step

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 from a few hours to a few days, depending on the number of gaps and the access. Somewhere like St Lawrence Bay needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Let us know about parking restrictions
  • Let us know about stairs, lifts or work at height
  • Tell us about any water getting in

Advice

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Signs you need fire rated sealant in St Lawrence Bay

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

Most people get in touch after spotting one of these:

  • Ordinary sealant used where a fire-rated product was needed
  • Damaged fire sealant left by other trades
  • New service routes left unsealed after building work
  • Linear gaps at the head of walls

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

10 questions to ask before booking

Surface by surface

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we’ll mention anything we notice.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail and we flag any that need another system.

St Lawrence Bay questions

Do you work for landlords with property near Southminster station?

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Do you cover smaller places like St Lawrence Bay?

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.

Can you match the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Can you tell me which gaps need fire stopping?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

Can ordinary silicone be used in a fire-stopping gap?

No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
