Looking after it afterwards

To keep the joints looking good and working properly:

  • Check the joints during routine room inspections
  • Keep strong chemicals and scourers off the joints
  • Log resealing so you know what’s due
  • Don’t leave a failed joint until the next refurbishment

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.

In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.

About our commercial sealant in Highleigh

In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, fitting around residents and staff. If you are dealing with whole floors of tired en suites and leaking joints in shower rooms and changing areas, we can put it right.

Work in a small place like Highleigh is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.

Whatever the size of the job, you get the same one-year guarantee in Highleigh and across West Sussex.

Commercial buildings in Highleigh

For seaside hotels, guest houses and holiday lets around Highleigh, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. There are hotels and other places to stay in and around Highleigh. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Community buildings like St Mary Our Lady Sidlesham are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else. For site and facilities teams at buildings such as Sidlesham Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For landlords with property near Chichester station, sealant work can be quoted for a single flat or a whole portfolio.

Different surfaces, different methods

Welfare facilities

Before a health and safety visit or audit, tired sealant is easy to sort. Let us know when it needs to be done and we will schedule around it, cure time included.

Office washrooms & kitchens

Kitchen and tea point joints are degreased and resealed, using a food-safe sealant by sinks where it’s needed.

Honest limits

A few problems are outside what sealant work can do:

  • A shower tray, bath or basin that’s cracked or broken
  • A broken extractor fan behind the mould problem
  • Water damage behind the tiles that needs a tiler or builder

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

The process

Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per room, so whole buildings are phased. Somewhere as small as Highleigh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with a site walk to agree the rooms and the timing.
  2. Every area is sheeted and the old silicone stripped out.
  3. We clean the joints, treat any mould and let them dry.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Each room is checked and handed back with its cure time.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Let us know about stairs, lifts or work at height
  • Keep children and pets away from the work area
