Bath resealing in Netherwitton

Bath resealing in Netherwitton, done in place

All of the old sealant is cut out, deal with any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. Our technicians work on basins & vanity units, baths and kitchen worktops & sinks, and people most often call us about water getting behind the bath or tray and black mould in the sealant.

You get a one-year guarantee, the same in Netherwitton as everywhere else we work.

How to look after the repair

Once the work has cured, treat it gently:

  • Dry the seal after bathing
  • Don’t stand toiletries on the seal
  • Let steam out after showers
  • Run the extractor fan during and after showers

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

Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.

DIY kit or professional repair?

If you’re set on a kit, follow its instructions closely, and don’t use it until it has fully cured. If it fails, we can still put it right.

We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.

What we do, step by step

Nothing needs to be moved out of the room. We bring everything we need with us, put protection down and start once you’re happy with the plan. It usually takes a couple of hours, and you’re welcome to carry on with your day while we work.

  1. The surrounding area is protected and the joints masked.
  2. Old sealant and residue are removed.
  3. The joint is cleaned, treated and dried.
  4. Fresh silicone is applied in a continuous bead.
  5. We smooth the bead, remove the tape and leave it to cure.

Before we arrive

  • Avoid using the area for a few hours before we arrive
  • Tell us if there are stairs or a lift
  • Keep a parking space free if you can

Advice

What bath resealing costs

We do not charge extra for travel to Netherwitton. The price depends on:

  • Whether old repairs or coatings need taking off
  • How easy the damage is to reach
  • The material
  • Unusual colours or finishes

Compared with replacing, a repair is usually a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.

Getting a price from photos

You can normally get a fixed price without us visiting. To help us price it:

  • A close-up of the damage, in focus
  • Good light, ideally daylight, without flash glare
  • A coin or ruler next to the damage for scale
  • One picture of the whole bath or shower

Most customers in Netherwitton get their price from photos. Add a line about what happened and your postcode, and we will reply with a fixed quote and the earliest dates we have.

Is resealing worth it?

Resealing is a small job. Putting off a reseal lets water get behind the bath or tray, which costs far more to put right. The price depends on how much damage there is and what kind, the material and how many items we do on one visit. You get a fixed quote from your photos, so you know the cost before booking.

Why book with us

  • Work done at your home or business
  • CHAS, Constructionline and SafeContractor accredited
  • A fixed quote before you book
  • We’ll tell you if it’s not worth repairing

Read our pricing.

For landlords and businesses

Builders use us to fix snagging damage before handover, saving last-minute replacements. Several plots can be done in one visit to keep costs down.

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

Signs you need bath resealing in Netherwitton

Joints split if the bath or tray moves, frequently because it was sealed while the bath was empty.

It’s worth getting a quote if you see:

  • Damp near the bath
  • Sealant that is split or lifting
  • Silicone smeared on tiles
  • Stained silicone

Questions to ask before you book

  • The length of the guarantee and what it covers
  • How to look after the finish
  • Whether a trained technician does the job
  • A fixed quote, and whether VAT is included

Choosing a repair company

When a repair isn’t the answer

A repair isn’t right for every job, for example:

  • Loose tiles, which need refixing first
  • Rotten walls or floors behind the bath
  • Gaps so wide they need filling or trims before sealing

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

What we work on

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

Questions from Netherwitton

Why does the silicone keep cracking?

Generally because the bath or tray moves, or it was sealed with the bath empty. We seal baths full of water.

Are you accredited?

Yes, including CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.

Is there a call-out fee?

We do not add a call-out fee. The fixed price covers the visit and the work.

Is it worth repairing rather than replacing?

Usually, when the rest is in good condition. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.

Will the price change on the day?

We’ll show you and explain before doing anything extra. You will not be charged for anything you haven’t agreed.

Why does mould come back so fast?

Typically poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.

How long will it take?

Generally a couple of hours, plus curing time.

Can I add another job to the visit?

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