Fire rated sealant near Crow Green

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Crow Green, access is often the only tricky part. 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. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  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.

Getting ready for the visit

  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
  • Where the joints are inside, avoid wetting them before we arrive

Fire rated sealant for homes and businesses in Crow Green

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. If you are dealing with new service routes left unsealed after building work and linear gaps at the head of walls, we can put it right, whatever the surface.

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

All of our work is guaranteed for twelve months, in Crow Green and everywhere else we cover.

What sealant work cannot fix

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • Problems with the door itself rather than the gap around the frame
  • Certifying a building or signing off its fire safety
  • Big openings where sealant alone is not the tested solution

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

Crow Green questions

I let a flat near Shenfield station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.

Do you cover smaller places like Crow Green?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Where are you based?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you carry out fire risk assessments?

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

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.

Can I choose the sealant colour?

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.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Can you work in occupied buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged if that suits the building.

Workplaces and buildings in Crow Green

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 let a flat or house near Shenfield station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Larchwood Primary School, fire-stopping around service openings should be restored whenever new services go in.

DIY versus a professional finish

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.

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

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We take into account:

  • Mould in or behind the old joints
  • How easy the joints are to reach
  • The old material and how stubborn it is
  • The number and length of the joints

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What we need to know

Before you ask for a quote, have a think about:

  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • If someone has resealed it before
  • Photos by email, if that is easy

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Leave it or put it right?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own and needn’t wait for anything else. Older cottages and farmhouses around Crow Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

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. Ask us for a quote and we’ll explain what it covers.

Why us?

  • Neat joints and a tidy finish
  • One-year guarantee on every job
  • Anti-fungal sanitary silicone in wet areas
  • Full insurance on every job

When to call us in Crow Green

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.

Signs it’s time to call us include:

  • Gaps flagged on a fire risk assessment
  • Standard silicone or caulk in a fire-stopping gap
  • New service routes left unsealed after building work
  • Gaps around pipes and cables through fire-resisting walls

If you look after a church, hall or community building such as Trinity Church, older buildings that have had new heating or wiring often have service gaps worth checking.
