Bath resealing in St Dennis

Bath resealing in St Dennis, done in place

A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they protect the walls and floor. Common call-outs are for an untidy old seal and mould you can’t clean out, on baths, wet rooms and kitchen worktops & sinks.

We guarantee the work for a year. If something is not right in that time, we come back and put it right.

Honest limits

A few problems are outside what a surface repair can do:

  • Movement in the bath or tray
  • Very wide gaps that need a trim
  • Hollow or loose tiles

If in doubt, send pictures and we’ll say what we think before you book.

Surfaces we repair

  • Shower trays & enclosures
  • Kitchen worktops & sinks
  • Basins & vanity units
  • Baths
  • Wet rooms

How the visit works

The work is clean and fairly quiet, so you can stay at home while we are there. We protect the area first, then the work takes a couple of hours. Before we leave, we explain how soon it can be used and how to look after it.

  1. All the old sealant is cut out and removed.
  2. Next we clean the joint and deal with mould.
  3. We dry the joint thoroughly.
  4. We fill a bath with water before sealing so the gap is at its widest.
  5. New mould-resistant silicone goes on and is tooled to a neat finish, taps included.

Preparing for the visit

  • Let us know if it has been repaired before
  • Keep pets and children out of the room while we work
  • Keep a parking space free if you can

Resealing in St Dennis: why it matters

Resealing is routine maintenance. Leaving split or mouldy sealant lets water get behind the bath or tray, which costs far more to put right. Rather than charging by the hour, we fix the price before we start. It depends on the damage, the material and access.

Why us?

  • Fixed prices from your photos
  • We come to you, anywhere in the UK
  • One-year guarantee on every repair
  • One price list for the entire UK

Take a look at our pricing.

For landlords and businesses

Landlords, letting agents and housing providers in St Dennis use us as well as householders. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

Will there be a smell?

There can be some smell while we work, which is why we ventilate. It clears as the materials cure.

Aftercare tips

To keep it looking its best:

  • Keep bottles off the joints
  • Give the seal a regular clean
  • Ventilate the bathroom well
  • Wipe the joints dry after use

Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.

Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.

DIY kit or professional repair?

Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.

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, it’s worth having it done properly.
