Need fire rated sealant in Liss?

The process

The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours for a handful of gaps, and longer for a whole building. In a smaller place like Liss, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed
  • Tell us about any previous sealing or DIY attempts

Fire rated sealant in Liss, done properly

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and common reasons people get in touch are unsealed gaps around fire door frames and linear gaps at the head of walls.

Around a place like Liss, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Quotes for fire rated sealant in Liss

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

  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • Whether there’s mould to deal with
  • Any working-time requirements on site

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

There’s no need for technical detail. Just tell us:

  • The rough size of the job
  • The address or postcode of the job
  • A few photos by email, if you can
  • What’s wrong with the joints now

We do not publish a price list. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.

How the job changes by surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Honest limits

Before you book, it’s worth knowing the limits too:

  • Big openings where sealant alone is not the tested solution
  • Problems with the door itself rather than the gap around the frame
  • Walls or floors that weren’t built to resist fire

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

Joints and surfaces we work on

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

Can I do it myself?

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Liss: your questions answered

Do you work for landlords with property near Liss station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.

Do you cover smaller places like Liss?

Yes, Liss 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.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.

How long will you be here?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Larger jobs naturally take longer, and we’ll say how long yours will take.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Where are you based?

We are based in Crawley, and we work across South East England, London and Scotland.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Ask every contractor to reseal any fire stopping they disturb
  • Flag any open gap you spot round a pipe or cable
  • Don’t paint over fire sealant until it has cured
  • Check risers, ceiling voids and cupboards during building checks

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Workplaces and buildings in Liss

There are hotels and other places to stay in and around Liss. Hotel work can be planned room by room, with out-of-hours working where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Schools such as Liss Infant School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Liss station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
