Bath resealing in Lee, done in place

We cut out all of the old sealant, deal with any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. Our technicians work on basins & vanity units, wet rooms and shower trays & enclosures, and common reasons people get in touch are missing sealant behind the taps and old sealant that looks dirty.

Every job is backed for twelve months, and the guarantee is the same wherever you live. If something goes wrong with the work, we come back.

What happens on the day

Arrival times are agreed in advance, so you are not left guessing. Once we are there, the work takes around two hours for most jobs. We leave the room clean and you will know when it can be used.

  1. We protect the area and mask the joint lines.
  2. We remove the old sealant and every trace of residue.
  3. The joint is cleaned, treated and dried.
  4. Fresh silicone is applied in a continuous bead.
  5. The bead is smoothed, the tape removed and the seal left to cure.

How to prepare

  • Make sure the room can be ventilated
  • Let us know about parking or access
  • Keep children and pets away from the room on the day

Why it’s worth resealing in Lee

Resealing costs very little. Failed sealant can lead to water damage that is much more expensive. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send photos and you’ll get a fixed figure.

DIY repairs versus a professional job

The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.

For a hairline mark somewhere you’ll never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.

Work for landlords and builders

We’re used to working with agents and managing companies. Send the address, photos and access details.

We carry out planned and one-off repairs for housing associations and facilities teams. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.

Materials and what they mean for the repair

Baths

We fill the bath before sealing, so the joint is at its widest.

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

Questions from Lee

Can you redo someone else’s repair?

Yes, we frequently do. Removing the old work can add time, and that is in the quote.

Do you come to Lee?

Yes. We work across the UK and travel to Lee and the rest of Greater London. Send photos and we will quote, or call 0345 017 0787.

How long will it take?

Usually a couple of hours, plus curing time.

What if the damage is worse than the photos show?

We’ll show you and explain before doing anything extra. Nothing extra is done without your say-so.

Is repairing better than replacing?

Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we will tell you.

How quickly can you book me in?

Your quote comes with available dates. Tell us if you need it done quickly.

Is there a guarantee?

Every repair comes with our one-year guarantee. We will explain what it covers when we quote.

Is it messy?

Dust sheets and masking go down before we start, and we clean up when we’ve finished.

How to look after the repair

Once the work has cured, treat it gently:

  • Replace the seal when mould sets in
  • Run the extractor fan during and after showers
  • Let steam out after showers
  • Clean the sealant gently and regularly

Let it cure fully before using the bath or shower, normally about a day.

Damp below or loose tiles need checking quickly. There may be more going on, and we will say if you need a builder or plumber.

Do you need bath resealing in Lee?

Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning cannot get it all out.

Send us a picture if you notice any of these:

  • Water getting behind the bath or tray
  • Silicone smeared on tiles
  • Unsealed corners
  • Black spots in the silicone

Questions to ask before you book

  • What the guarantee covers, and for how long

  • What preparation is included
  • What happens if the damage is worse than the photos show
