Remedial sealant in Slindon

Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. Typical jobs include sealant applied over old sealant that has lifted and black mould underneath the bead, on expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.

Somewhere as small as Slindon, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

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.

When it is not the sealant

It helps to know what we can’t do:

  • Older mastics that may need an asbestos check before removal
  • A bath, tray or worktop that moves until it’s properly fixed
  • A cracked shower tray or bath (that needs repair or replacing)

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Where we work in Slindon

  • Shrunken worktop sealant
  • Leaking tray & enclosure joints
  • Expansion joints
  • Mouldy bath & shower sealant
  • Botched or over-sealed joints
  • Failed movement joints

Signs you need remedial sealant in Slindon

Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.

The problems people usually mention when they call are:

  • Products that weren’t meant for the joint
  • Sealant peeling off a dusty or damp surface
  • Kitchen joints letting water behind the worktop
  • A shower that leaks however often it’s resealed

If you let a flat or house near Barnham station, a joint that keeps failing is best fixed properly while the property is empty.

Our hiring checklist

What happens on the day

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Slindon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. We finish neatly and point out anything that needs another trade.

Preparing for the visit

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Tell us about access, such as stairs, a lift or high-level joints

Why deal with it now?

A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Slindon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Why us?

  • Approved under the ARBOMaster scheme
  • Sanitary silicone with an anti-fungal additive in wet areas
  • We never seal over old sealant
  • Trusted Arbo and Everbuild sealants

Bathrooms and kitchens in Slindon

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Homes close to The Parish Church of St Mary include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as Slindon CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What if the leak is not the sealant?

We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

How the job changes by surface

Leaking trays & enclosures

Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.

Over-sealed & botched joints

Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
