Need fire rated sealant in Fareham?

What we are called out for in Fareham

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Keep an eye out for these signs:

  • Cracked or shrunken fire-rated sealant
  • Ordinary sealant used where a fire-rated product was needed
  • Linear gaps at the head of walls
  • Holes left by a change of layout

If you look after a building such as St Jude's Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What your quote should include

  • What guarantee comes with the work
  • What happens if they find a problem under the old sealant
  • What the quote includes, VAT included or not
  • Whether they’re fully insured

Our hiring checklist

Fire rated sealant in Fareham, done properly

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. Common call-outs are for gaps left after a refit or conversion and open holes round services passing through fire walls, on door frames, flats & HMOs and pipe & cable gaps.

Washrooms in busy buildings wear their sealant out faster than a bathroom at home, while fire-rated sealant has to be made good whenever new pipes or cables go through. For a building in Fareham, we plan timings around how it’s used.

Big or small, it’s backed by our 12-month guarantee in Fareham and across Hampshire.

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

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Can you give us a record of the work?

Yes. You get a list of where we worked and what we used to keep with your fire safety documents.

Can I choose the sealant colour?

Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

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

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

What we do, step by step

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. For a job in Fareham, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  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. Locations and products are noted so you have them on file.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Let us know if you’ve seen damp or leaks
  • Keep children and pets away from the work area

Quotes for fire rated sealant in Fareham

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

What to tell us for a quote

You don’t need to know the technical terms. Just tell us:

  • The type of property
  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • What’s wrong with the joints now

Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.

DIY versus a professional finish

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Honest limits

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

  • Construction that doesn’t provide fire resistance on its own
  • Issuing a fire rating or certificate for a building
  • Problems with the door itself rather than the gap around the frame

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

Surfaces we seal

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

Why it’s worth doing now in Fareham

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. In a family home in Fareham, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Why us?

  • Neat joints and a tidy finish
  • Quality sealants from Arbo and Everbuild
  • ARBOMaster approved applicator
  • We’re fully insured
