Fire rated sealant in Crowborough, done properly

We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with open holes round services passing through fire walls and standard silicone or caulk in a fire-stopping gap, we can help.

Washrooms in busy buildings wear their sealant out faster than a bathroom at home, and fire-rated joints need restoring whenever new services are run through a wall. For a building in Crowborough, we plan timings around how it’s used.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What sealant work cannot fix

To be straight with you, there are a few things sealant won’t fix:

  • Fire risk assessments, which need a qualified assessor
  • Construction that doesn’t provide fire resistance on its own
  • Large holes that need a different fire-stopping system

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Surfaces we seal

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

How it works

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. In Crowborough, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Before we arrive

  • Let us know about parking restrictions
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

Quotes for fire rated sealant in Crowborough

What we need to know

When you call or email, these details help:

  • A few photos by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the property is
  • Whether it has been sealed before

There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.

Looking after it afterwards

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

  • Ask which product was used before you paint
  • Keep the record of products and locations with your fire safety documents
  • Check risers, ceiling voids and cupboards during building checks
  • Report cracked or damaged seals as soon as you notice them

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Fire rated sealant in Crowborough: local notes

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 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 The Parish Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Crowborough station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as St Marys Catholic Primary School, fire-stopping around service openings should be restored whenever new services go in.

Your questions about fire rated sealant in Crowborough

Do you work for landlords with property near Crowborough station?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

What fire rating will the seal have?

We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.

Can you give us a record of the work?

Yes. We record the locations we have sealed and the products used for your files.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

For landlords and businesses

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Surface by surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment.
