Can I fix it myself?

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

A DIY attempt is not a disaster. We take the old repair out and do it properly, so it won’t stop us repairing it. Just mention it when you send pictures, as it can add time.

What your bath or shower is made of matters

Shower trays

Trays are sealed with weight on them, for the same reason.

Baths

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

Why reseal now?

A professional reseal costs little compared with water damage. It’s a quick job that protects your walls and floors. What it costs depends on the type and amount of damage, the material and how many items we do on one visit. We give a fixed price from your photos, so you know the cost before booking.

Why book with us

  • Honest advice, even when it means no job
  • Technicians who travel to you, UK-wide
  • One-year guarantee on every repair
  • No need to remove anything

What we cannot put right

We will not take on work that will not last, so these are the limits:

  • A bath or tray that moves, until its support is fixed
  • Loose tiles, which need refixing first
  • Gaps so wide they need filling or trims before sealing

Send us pictures and we’ll tell you honestly before you book.

What we work on

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

Aftercare tips

Looking after the surface is easy, and it makes a real difference:

  • Reseal at the first sign of lifting
  • Air the room after use
  • Keep bottles off the joints
  • Wipe the joints dry after use

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

Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. An early reseal keeps water where it belongs.

Do you need bath resealing in Whetstone?

Sealant splits when the bath or tray moves, often because it was sealed with the bath empty.

If you can see any of these, send us a picture:

  • Unsealed corners
  • Old sealant that looks dirty
  • Leaks at the edges
  • Black mould in the sealant

How to compare quotes

How the visit works

Once we’re through the door, the aim is to do the job without disturbing the rest of your home. Surfaces nearby are masked off, the work takes about two hours for a bath, and we finish by cleaning up and talking you through the result.

  1. First we strip out every bit of the old mastic.
  2. Next we clean the joint and deal with mould.
  3. We ensure the joint is completely dry.
  4. Baths are filled with water first, so the joint is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.

How to prepare

  • Keep a parking space free if you can
  • Mention any earlier repairs or resurfacing
  • Clear toiletries, mats and anything else from around the area

Advice

Prices and what affects them

Each job gets its own fixed quote. This is what makes a difference:

  • How many items we do on one visit
  • The colour and finish to match
  • The type of damage
  • How easy the damage is to reach

No two jobs are quite the same, so we price each one individually. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.

Quotes from your pictures

Good photos mean an accurate price. Here’s what helps:

  • Any details about the material
  • Where you are, by postcode
  • Daylight if possible, and no flash reflection
  • A close-up of the damage, in focus

Pricing is simple: take a close-up of the damage and a picture from further back, send them to us with your postcode, and we’ll reply with a fixed price. There’s no charge for the quote and no obligation.

Questions from Whetstone

Can I add another job to the visit?

Yes. Doing several items on one visit typically costs less than separate visits. Include pictures of each item.

Do you do work for letting agents?

We do, regularly. We can quote for several properties together and work between tenancies.

Is it worth repairing rather than replacing?

Normally, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.

I rent my home. Can I book you?

We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Can pets and children be at home?

Yes, as long as they stay out of the room we’re working in. We will let you know when it’s safe to use again.

Is it messy?

Dust sheets and masking go down before we start, and tidy up before we leave.

Can you repair something that is been repaired before?

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

How long does silicone take to cure?

Normally about a day later. We’ll tell you the exact time.
