Fire rated sealant for Lucas Green homes and businesses

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

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

Fire rated sealant in Lucas Green

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you are dealing with joints picked up in a fire-stopping survey and linear gaps at the head of walls, we can put it right, on service penetrations, pipe & cable gaps and plasterboard & masonry alike.

Somewhere as small as Lucas Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

Each job carries a 12-month guarantee.

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Somewhere like Lucas Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Mention any parking rules near the property
  • Keep children and pets away from the work area
  • Mention any tricky access

Questions from Lucas Green

Will you come out to Lucas Green?

Yes, Lucas Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is Lucas Green in your area for fire rated sealant?

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

Can you tell me how many minutes the seal will last?

We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Get your landlord’s agreement first.

What’s the difference between intumescent and fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.

Can you seal over the old sealant?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame and we will tell you if we spot problems with the door.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.

What fire rated sealant looks like in Lucas Green

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’re given, installing the product to its tested details.

If you look after a building such as Bisley CofE Primary School, fire-stopping around service openings should be restored whenever new services go in. For buildings such as Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Brookwood station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What the job involves on each surface

Service penetrations

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

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing.

How we quote for fire rated sealant

Every job gets its own quote. This is what makes a difference:

  • Which sealant suits the joint
  • Working hours on commercial sites
  • Mould in or behind the old joints
  • How many areas need sealing

Rather than a set price list, 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.

What to tell us for a quote

When you call or email, these details help:

  • The type of property
  • Roughly how big the job is
  • What’s wrong with the joints now
  • A few photos by email, if you can

Need a quote? Please call 0345 464 0079 or email us with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

How to look after the new joints

Looking after new joints is easy:

  • Make resealing part of every contractor’s brief
  • Never patch a fire seal with standard sealant
  • Report cracked or damaged seals as soon as you notice them
  • Include hidden areas like risers in routine checks

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.

Landlord and commercial work in Lucas Green

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Letting agents and landlords in Lucas Green can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

When it is not the sealant

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system
  • A wall that isn’t a fire-resisting element to begin with

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