What the job involves on each surface

Student & care accommodation

Many accommodation blocks have rows of similar en suites. We agree a programme and work through them steadily.

Rental portfolios

An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.

Why act early in Clewer

Sealing over the old bead can seem the fastest option, but silicone does not bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. Around Clewer, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Common problems we fix in Clewer

In office kitchens and tea points, joints are wet and wiped all day, so sealant there wears and stains. Worktop and sink joints are often the first to go.

These are the problems we are asked about most:

  • Washroom sealant that looks dirty however often it’s cleaned
  • Tired sealant ahead of a health and safety audit
  • Sealant failing again soon after quick repairs
  • Rental bathrooms that need resealing between tenants

If you look after a church, hall or community building such as Church of St Andrew, any kitchen and washrooms need the same sealant care as any other building.

How the visit works

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of rooms. A visit to Clewer is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints

Advice

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Pass on the cure time to whoever cleans the rooms
  • Don’t leave a failed joint until the next refurbishment
  • Put a squeegee in each shower
  • Check the joints during routine room inspections

Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.

Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
