Bath resealing in Erith without replacing anything

Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, as one neat, continuous bead. We’re frequently asked to fix damp near the bath and missing sealant behind the taps, on basins & vanity units, wet rooms and shower trays & enclosures.

All our work is covered by our one-year guarantee.

What your bath or shower is made of matters

Sinks and worktops

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

Shower trays

We put weight on a tray before sealing it, for the same reason.

Why reseal now?

Resealing costs very little. Failed sealant can lead to water damage that is much more expensive. We charge the same wherever you are, so there’s no premium for Erith. What changes the price is the job itself: the material, the amount of damage and how many items.

Why book with us

  • No need to remove anything
  • One-year guarantee on every repair
  • We leave the room as we found it
  • A fixed quote before you book

Read our pricing.

What bath resealing costs

Every quote is fixed and free. What we take into account:

  • Whether it’s a chip, crack, burn or wear
  • Access to the area
  • Previous DIY repairs that have to come out
  • How hard the colour is to match

There are no surprise extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.

Quotes from your pictures

We price nearly every job from photos. This is what we need:

  • Natural light rather than flash
  • The postcode, so we can plan the visit
  • A close-up of the damage, in focus
  • A coin beside the damage so we can judge size

For most jobs, pictures are all we need to give you a price. Add a line about what happened and your postcode, and we’ll send back a fixed quote and some dates.

Honest limits

Some problems need a builder, plumber or fitter rather than us:

  • Loose tiles, which need refixing first
  • Very wide gaps that need a trim
  • A flexing bath

Send us pictures and we’ll tell you honestly.

Surfaces we repair

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

Erith: your questions answered

What information do you need?

A close-up, a wider photo and your postcode. After that, we just agree a date.

What areas do you cover?

All of Greater London, and the rest of the UK. Travel is included in the price.

Is it messy?

Very little mess: we sheet and mask everything nearby, and we take our waste away with us.

What happens next?

We come back with a fixed quote, plus dates. There is no obligation to book.

Why does mould come back so fast?

Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.

Can I add another job to the visit?

Yes, and it’s often cheaper. Just add the extra items to your photos and we’ll quote them together.

Is the work guaranteed?

Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.

Why does the silicone keep cracking?

The bath or tray is probably flexing. If it keeps happening, the support may need fixing.

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. Doing it properly first is typically the cheaper route.

It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.

Landlord and trade work in Erith

Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.

Letting agents often send us pictures straight from the inventory. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.

Do you need bath resealing in Erith?

Most reseals are because of black mould. It grows into the sealant itself, so cleaning only removes the surface.

Send us a picture if you notice any of these:

  • Discoloured, yellow sealant
  • Black spots in the silicone
  • Unsealed corners
  • Sealant that is split or lifting

10 questions to ask before booking

What we do, step by step

You do not need to empty the room beforehand. Everything we use comes in the van with us, lay protective sheets and start once you’re happy with the plan. Most jobs take about two hours for a bath, and you can get on with other things while we are there.

  1. The surrounding area is protected and the joints masked.
  2. Old sealant and residue are removed.
  3. We clean, treat and dry the joint.
  4. We run a continuous bead of new silicone.
  5. The bead is smoothed, the tape removed and the seal left to cure.

Preparing for the visit

  • Move bottles, mats and clutter away from the area
  • Tell us about any previous repairs or coatings
  • Let the surface dry out before the visit

Getting a price

We price from pictures so you do not have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and you’ll get a fixed figure back.
