Fire rated sealant in Church End

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What fire rated sealant looks like in Church End

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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

Schools such as St Mary's CofE Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Harlesden station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Looking after it afterwards

So the new joints stay in good condition:

  • Do not paint over fire sealant until it has cured
  • Never patch a fire seal with standard sealant
  • Get damaged fire seals looked at promptly
  • Check risers, ceiling voids and cupboards during building checks

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

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.

What happens on the day

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Church End. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Getting ready for the visit

  • Mention any tricky access
  • Plan for the work area to be out of bounds to pets and children
  • Mention any leaks or damp you’ve noticed

Advice

FAQs for Church End

Can you help a landlord with a rental near Harlesden station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Is Church End in your area for fire rated sealant?

Yes, Church End is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings. The product needed can limit the range.

Do you carry out fire risk assessments?

No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.

Do you have insurance?

Yes. We’re fully insured, and we can confirm the details when we quote.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is usually more efficient.

How long does fire rated sealant take?

It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll give you a better idea when we quote.

When something else is needed

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

  • Certifying a building or signing off its fire safety
  • Fire doors that need new seals, closers or hardware
  • Assessing a building’s fire safety

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Surfaces we seal

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

What affects the quote in Church End

Jobs vary more than people expect. The main factors:

  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with
  • Any working-time requirements on site

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

What to tell us for a quote

What to tell us when you ask for a quote:

  • Where the property is
  • How we’d reach the joints
  • A few pictures by email, if you can
  • The type of property

To get a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.

What the job involves on each surface

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

What we are called out for in Church End

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

Keep an eye out for any of the following:

  • Open joints along the top of partitions
  • Fire seals that have cracked with movement
  • Joints picked up in a fire-stopping survey
  • Open holes round services passing through fire walls

As a London address, Church End can be tricky for parking: let us know about parking bays, permits or a driveway.

What your quote should include

  • How the surfaces are prepared before sealing
  • Whether all the old sealant comes out first
  • How much experience the applicator has
  • What insurance they hold
