Questions from Castleton

Do you work in Castleton?

Yes. We work across the UK and travel to Castleton and the rest of North Yorkshire. Send us photos for a fixed quote, or call 0345 017 0787.

It’s been repaired before. Can you still fix it?

Usually, yes. The old repair comes out first.

How long does silicone take to cure?

You’ll get the curing time from us, typically around a day.

Will the price change on the day?

We stop, show you and agree any change before carrying on. Nothing extra is done without your say-so.

What happens once I’ve sent photos?

We come back with a fixed quote, plus dates. You’re under no obligation.

Do I need to be at home?

Yes. The technician needs access to the room for the visit, at a time that suits you.

Is it OK to have pets in the house?

Just keep them out of the work area. We’ll tell you when the room can be used again.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Many landlords are happy for a repair to be arranged before the end of a tenancy.

About our bath resealing in Castleton

A good reseal is all about preparation: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, in a neat, continuous bead. Typical jobs include unsealed corners and water getting behind the bath or tray, across baths, basins & vanity units and kitchen worktops & sinks.

The work is guaranteed for twelve months. If there’s a problem with the repair within the year, we return and sort it.

When to call us in Castleton

Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.

The things clients normally mention when they call include:

  • Gaps in the seal
  • Silicone smeared on tiles
  • Water getting behind the bath or tray
  • Discoloured, yellow sealant

Before booking anyone

  • Whether there are any call-out or travel charges
  • Whether the colour is mixed to match
  • The length of the guarantee and what it covers
  • What protection goes down before work starts

How to compare quotes

Honest limits

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
  • Water damage behind the bath that needs a builder

If in doubt, send photos and we will say what we think before you book.

Materials we work on in Castleton

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

Different materials, different repairs

Baths

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

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.

How we price bath resealing

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

  • The colour and finish to match
  • The material and finish
  • Doing more than one item at once
  • How easy the damage is to reach

A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send pictures and you will get a fixed figure.

Send photos for a quote

Phone pictures are fine. Ensure they show:

  • A clear, close picture of the problem area
  • Any earlier repairs or coatings
  • A coin beside the damage so we can judge size
  • The material, if you know it

Getting a quote takes a couple of minutes: photograph the damage, then the entire bath or shower, add your postcode and send them over. What comes back is a fixed price, not a guess.

Why reseal now?

Resealing is routine maintenance. Putting off a reseal lets water get behind the bath or tray, which costs far more to put right. We do not add extras on the day. What we quote from your photos is what you pay, unless the damage turns out to be different, in which case we talk to you first.

Why Castleton clients choose us

  • One visit for most repairs
  • Technicians who travel to you, UK-wide
  • Honest advice, even when it means no job
  • Everything repaired in place

DIY kit or professional repair?

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 normally cheaper.

We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.

The process

When we visit, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. The job typically takes a couple of hours. We tidy up before we leave and let you know when you can use it again.

  1. We cut out and remove all of the old sealant.
  2. Next we clean the joint and deal with mould.
  3. We ensure the joint is completely dry.
  4. For a bath, we fill it with water first so the joint is at its widest.
  5. We apply new mould-resistant silicone and tool it to a neat finish, taps included.

Getting ready for the visit

  • Avoid using the area for a few hours before we arrive
  • Clear toiletries, mats and anything else from around the area
  • Let us know about parking or access

How to get a price

To get a price, send two or three pictures through our quote form or call us. We will tell you honestly if a repair is the right fix.

Keeping it looking good

Good habits make a big difference to how long a repair lasts:

  • Replace the seal when mould sets in
  • Dry the seal after bathing
  • Air the room after use
  • Store bottles on a shelf

Avoid scraping the joints, and keep shampoo bottles off the joints.

Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
