Bathroom resealing in AL5: how it works

The secret of a lasting bead is the preparation. Every bit of old silicone comes out, down to the thin film left on the tiles, after which the joint is degreased and any mould treated. Only once it’s dry does the new bead go on. We work on kitchen worktops & upstands, shower trays & enclosures and basins & vanity units, and common reasons people get in touch are water getting behind the kitchen upstand and gaps where the bath or tray has moved.

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen.

  1. We cover the area around the joints we are working on.
  2. We cut away the old sealant and clean off what’s left.
  3. Mould is treated, then the joint is left to dry thoroughly.
  4. Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
  5. The joint is finished neatly and we explain when it can get wet.

Where we work in AL5

From Harpenden, Batford and Kinsbourne Green to its smaller places, homes across AL5 have bathrooms and kitchens of every age. Family bathrooms, rented flats and hotel en suites all need their sealant and grout renewing in time.

London and the South East are among the drier parts of the UK, but outdoor sealant still needs a dry day and clean surfaces, so outside work in AL5 is planned around the forecast.

Harpenden: If you let a flat or house near Harpenden station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. For site and facilities teams at buildings such as Harpenden Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface

Basins & vanity units

Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so a neat, continuous bead matters.

Wet rooms

Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.

What we’re called out for in AL5

Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.

Most people get in touch when they notice one of these:

  • Two layers of silicone, both failing
  • Gaps between the worktop and the wall
  • Water escaping at the shower enclosure
  • Lumpy, uneven sealant from a DIY attempt

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Avoid abrasive pads on the sealant
  • Move toiletries away from the joint
  • Stick to a soft cloth and a mild cleaner
  • Keep an eye on the corners, where splits start

Check the sealant now and then. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.

A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.

How we quote for bathroom resealing

Every job gets its own quote. These are the things that affect it:

  • Whether the work is at height
  • The number and length of the joints
  • The number of rooms or windows
  • Working hours on commercial sites

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any access issues, like height or stairs

Need a quote? Please call 0345 464 0079 or email us and tell us about the job. We will explain what we’d do and send you a clear quote before we start.
