Bath resealing at your home in Clapham

A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. We work on basins & vanity units, kitchen worktops & sinks and shower trays & enclosures, and the jobs we see most are leaks at the edges and unsealed corners.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Materials and what they mean for the repair

Shower trays

We put weight on a tray before sealing it, so the joint is at its widest.

Baths

We fill the bath before sealing, to open the joint fully.

Common questions in Clapham

Can you repair something that’s been repaired before?

Generally, yes. Let us know what was used before and we’ll plan for it.

What happens once I’ve sent pictures?

We check the damage, the material and your postcode, then reply with a quote.

Why does the silicone keep cracking?

The bath or tray is probably flexing. Persistent splitting can mean the support needs attention.

Can I add another job to the visit?

Yes. Combining jobs on one visit brings the cost down. Include photos of each item.

Is there a call-out fee?

We do not add a call-out fee. Your fixed price includes everything.

Is there a guarantee?

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

What happens if you find more damage?

Your quote covers the damage in the photos. If there’s more, we’ll tell you before starting.

When can I use the bath after resealing?

We’ll give you the curing time, usually around a day.

The process

Here’s how a visit usually runs: we arrive on time, protect everything around the work area, do the job and clear up. Plan for about two hours for a bath. Before leaving, we tell you when it can be used and what to avoid for the first few days.

  1. First we strip out every bit of the old mastic.
  2. The joint is cleaned and any mould treated.
  3. We ensure the joint is completely dry.
  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

  • Keep a parking space free if you can
  • Let us know which floor the room is on
  • Clear toiletries, mats and anything else from around the area

Ask for a price

A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, include your postcode and send them to us. What comes back is a fixed price, not a guess.

What bath resealing costs

There’s no charge for travel to Clapham. The price depends on:

  • How much damage there is
  • What the surface is made of
  • Access to the area
  • The type of damage

A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send pictures and you will get a fixed figure.

Send photos for a quote

The better the pictures, the more accurate the price. Here’s what helps:

  • A coin beside the damage so we can judge size
  • The material, if you know it
  • One sharp close-up of the damage
  • The postcode, so we can plan the visit

Email us photos of the damage and a wider shot of the whole item, and tell us you are in Clapham, and we will reply with a fixed price.

Keeping it looking good

Good habits make a big difference to how long a repair lasts. Here’s what we suggest:

  • Reseal when black spots won’t clean off
  • Keep bottles off the joints
  • Dry the seal after bathing
  • Run the extractor fan during and after showers

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.

Is resealing worth it?

A professional reseal costs little compared with water damage. It’s a quick job that protects your walls and floors. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send photos and we’ll give you the exact figure.

DIY kit or professional repair?

If you do try a kit, read the instructions carefully, make sure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.

It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is generally cheaper.

What we’re called out for in Clapham

Sealant doesn’t last forever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint moves slightly every time the bath is filled.

People normally call us after spotting something like this:

  • Silicone coming away from the tiles
  • Stained silicone
  • Silicone smeared on tiles
  • Gaps by the taps

What to look for in a quote

  • What happens if the damage is worse than the photos show
  • A fixed quote, and whether VAT is included
  • How long the guarantee is and what it covers
  • How the room is protected while they work
