Bath resealing for Ashburton homes

Bath resealing in Ashburton, done in place

We reseal baths with them filled with water, so the joint opens fully, which stops the new seal tearing the first time the bath is used. We regularly repair kitchen worktops & sinks, wet rooms and shower trays & enclosures, and common reasons people contact us are damp near the bath and a messy previous reseal.

We stand behind the work with a one-year guarantee.

DIY repairs versus a professional job

If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.

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, and the work is guaranteed.

What we do, step by step

Arrival times are agreed in advance, so you’re not left guessing. Once we are there, the work takes about two hours for a bath for most jobs. We leave the room clean and ready to use once it has cured.

  1. The old silicone is cut out completely.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  4. The bath is filled with water, or weight put on the tray.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

Before we arrive

  • Tell us about parking, stairs or access
  • Let us know which floor the room is on
  • Move bottles, mats and clutter away from the area

Related advice

Keeping it looking good

Once the work has cured, treat it gently:

  • Use the extractor fan
  • Give the seal a regular clean
  • Let steam out after showers
  • Dry the seal after bathing

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

Black mould in sealant isn’t just unsightly; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.

Ashburton: your questions answered

How do I stop mould in sealant?

Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.

Can you reseal over the old silicone?

Never over old. It’s removed, cleaned off and the joint dried first.

What areas do you cover?

We cover the entire UK, including Ashburton and the rest of Greater London. Send your postcode with your photos and we’ll confirm dates.

I rent my home. Can I book you?

Yes. Ask your landlord first, and we can send them the quote if that helps.

What do you need from me?

Send pictures through the quote form or call 0345 017 0787.

How long before I can shower?

Generally after around 24 hours. We confirm before we leave.

Can landlords book you?

Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses in Ashburton.

Does someone need to be in?

Someone needs to let us in and show us the job. After that, you can carry on with your day.

What we cannot put right

Not everything can be repaired, and we would rather say so up front. Repairs will not solve:

  • Gaps too big for silicone alone
  • Loose tiles, which need refixing first
  • Hidden water damage

Send us photos and we’ll tell you honestly before booking.

Surfaces we repair

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

Landlords, agents and businesses in Ashburton

Housing associations and facilities teams use us for planned and reactive repairs in Greater London and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.

We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover so nothing needs replacing. We hold CHAS, Constructionline and SafeContractor accreditations.

What affects the price in Ashburton

You’ll know the full cost before you book. We look at:

  • Whether old repairs or coatings need taking off
  • Doing more than one item at once
  • Unusual colours or finishes
  • The type of damage

Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send photos and we will give you the exact figure.

Send photos for a quote

You can take the pictures on your phone. Ensure they show:

  • Good light, ideally daylight, without flash glare
  • One picture of the entire bath or shower
  • Details of any past repairs
  • Your postcode, so we can check dates

Pricing is simple: snap the damage close up and then the whole item, send them to us with your postcode, and we’ll reply with a fixed quote. Quotes are free and you’re under no obligation.

Resealing in Ashburton: why it matters

Putting new silicone over old doesn’t last. It soon peels, and mould stays trapped behind it. We remove the old sealant completely. The price reflects the work involved, not where you live. You will see the full price before you book, with nothing added on the day.

What you get with us

  • Accredited with CHAS, Constructionline and SafeContractor
  • Work done at your home or business
  • Free fixed quotes from pictures
  • Honest advice, even when it means no job

What your bath or shower is made of matters

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.

Shower trays

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