Fire-rated sealant in Balls Cross, West Sussex

  • Damaged fire sealant left by other trades

Fire rated sealant in Balls Cross

Fire rated sealant in Balls Cross, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you have gaps where walls meet ceilings or slabs and fire stopping disturbed by later work, we can help, whatever the surface.

For a small place like Balls Cross, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

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

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Check risers, ceiling voids and cupboards during building checks
  • Ask which product was used before you paint
  • Report cracked or damaged seals as soon as you notice them
  • Allow for resealing whenever new services are run

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

When to call us in Balls Cross

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

People generally contact us after spotting one of these:

  • Open joints along the top of partitions
  • Fire stopping disturbed by later work
  • Gaps flagged on a fire risk assessment
  • Unsealed gaps around fire door frames

For buildings such as Holy Trinity Church, gaps around pipes and cables are worth checking after any building work there.

Our hiring checklist

How the job changes by surface

Service penetrations

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

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

  • The number of rooms or windows
  • The old material and how stubborn it is
  • Access and height
  • Any working-time requirements on site

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • If someone has resealed it before
  • Where the job is, and your postcode
  • The problem you’ve noticed
  • Pictures of the joints, sent by email

For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.

When something else is needed

It helps to know what we cannot do:

  • Certifying a building or signing off its fire safety
  • Assessing a building’s fire safety
  • Walls or floors that weren’t built to resist fire

Not sure which it is? You can ring 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

The process

At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. For a village or hamlet like Balls Cross, the journey is planned in advance: 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 go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Before we arrive

  • On commercial sites, let us know about site rules
  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height

FAQs for Balls Cross

Will you come out to Balls Cross?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is fire rated sealant in Balls Cross guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.

Where do you work from?

Our base is in Crawley, and we work across South East England, London and Scotland.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access.
