What the job involves on each surface

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.

Worktops & kitchens

Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.

Remedial sealant in Highleigh, done properly

If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you call 0345 464 0079 or drop us an email. We work on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are repeat leaks from the same joint and over-sealed joints coming away.

In a village or hamlet like Highleigh, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

Your job is guaranteed for a year, as with all our work.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours, depending on how many layers have to come out. In a small place like Highleigh, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. We clean the joint, treat any mould and let it dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. The new joint is tooled neatly and we explain anything else we found.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints

Getting a quote

Advice

Bathrooms and kitchens in Highleigh

Highleigh is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Highleigh has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

If you look after a building such as Sidlesham Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Chichester station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Leave it or put it right?

DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Around Highleigh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Take a look at what affects the cost and what customers say.

Do you need remedial sealant in Highleigh?

Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

The most common problems we see are:

  • Gaps opening along the back of the worktop
  • Torn expansion joints
  • Repeat leaks from the same joint
  • Smears and lumps from a botched reseal

For an older house near a landmark such as St Mary Our Lady Sidlesham, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How to choose a mastic man

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What affects the quote in Highleigh

Some jobs are bigger than they look, and some smaller. The main factors:

  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • The size of the job
  • Any working-time requirements on site

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • How we’d reach the joints
  • Any previous sealing or DIY work
  • What’s wrong with the joints now
  • Whether it’s a home or a business

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Have loose fittings fixed before resealing
  • Check ceilings under showers for marks
  • Act on a lifting corner right away
  • Ask why a joint failed before redoing it

Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.

Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
