Aftercare tips

Much of the damage we repair could have been avoided. These habits help:

  • Run the extractor fan during and after showers
  • Replace the seal when mould sets in
  • Do not stand toiletries on the seal
  • Wipe the joints dry after use

Good ventilation is the best protection, and wipe the joints after use.

Black mould in sealant is not just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.

What affects the price in Newcastle

There are no hourly rates or hidden extras. The price is based on:

  • The material and finish
  • Whether we combine several jobs
  • Previous DIY repairs that have to come out
  • Where the damage is and how we get to it

A repair generally costs much less than people expect, particularly next to the cost of replacement. Photos let us give you the exact figure.

Getting a price from photos

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

  • Your postcode, so we can check dates
  • One picture of the whole bath or shower
  • Daylight if possible, and no flash reflection
  • A close-up of the damage, in focus

Send us a photo of the damage and one of the entire item, with your CF31 postcode, and we will reply with a fixed quote.

How it works

Once we’re through the door, we keep the work contained to the one room. Surfaces nearby are masked off, the job takes a couple of hours, depending on what we find, and we finish with a tidy-up and a look at the finished work together.

  1. The old silicone is cut out completely.
  2. We remove the residue and clean the joint.
  3. We treat mould and dry the joint thoroughly.
  4. We fill the bath, or weight the tray, to open the joint.
  5. New mould-resistant silicone is applied and tooled neatly.

How to prepare

  • Clear toiletries, mats and anything else from around the area
  • Have a window or extractor fan available
  • Let us know about parking or access

How to get a price

There’s no need for us to visit first. Nearly every job can be priced from photos: we need a close-up, a wider picture and your postcode, and we will come back to you with a fixed figure.

10 questions to ask before you book

Landlords, agents and businesses in Newcastle

We carry out planned and one-off repairs for housing associations and facilities teams in Bridgend and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

Newcastle: your questions answered

What information do you need?

Use the quote form or ring 0345 017 0787, and we will take it from there.

Do you cover Newcastle?

Yes. We cover the entire UK and travel to Newcastle and the rest of Bridgend. Send us pictures for a fixed quote, or call 0345 017 0787.

Do you cover the whole of Bridgend?

We cover the entire UK, including Newcastle and the rest of Bridgend. Just include your postcode and we’ll confirm dates.

What happens if you find more damage?

It’s rare, but if it happens we talk to you first. The price only changes if you agree.

Is a repair better than a new one?

Usually, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.

What happens after I send photos?

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

How do I stop mould in sealant?

Mould needs moisture. Ventilation and drying keep it clean longer.

Is the work guaranteed?

All our work carries our one-year guarantee. We will explain what it covers when we quote.

What your bath or shower is made of matters

Baths

We fill the bath before sealing, so the joint is at its widest.

Sinks and worktops

Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.

What we cannot put right

We won’t take on work that will not last, so here’s what a repair can’t put right:

  • Gaps too big for silicone alone
  • Water damage behind the bath that needs a builder
  • A bath or tray that moves, until its support is fixed

Not sure? Send photos and we’ll give you a straight answer.

Materials we work on in Newcastle

  • Baths
  • Basins & vanity units

  • Shower trays & enclosures
  • Kitchen worktops & sinks

DIY repairs versus a professional job

Kits are cheap and easy to find, but the repairs we redo most often are DIY ones that have discoloured or lifted. Doing it properly first is usually the cheaper route.

If you’re set on a kit, follow its instructions closely, and give it the full curing time. If it does not work out, we can still repair it properly.
