About our bath resealing in Northaw Valley

Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. Whether it’s black spots in the silicone and gaps by the taps, we can help, on basins & vanity units, wet rooms and baths alike.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping it looking good

So the finish stays in good condition:

  • Air the room after use
  • Wipe the joints dry after use
  • Give the seal a regular clean
  • Reseal when black spots won’t clean off

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

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.

How the visit works

From the moment we arrive, we keep the work contained to the one room. Surfaces nearby are masked off, the work takes around two hours, and we finish with a tidy-up and a look at the finished work together.

  1. First we strip out every bit of the old mastic.
  2. The joint is cleaned and any mould treated.
  3. We dry the joint thoroughly.
  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.

Preparing for the visit

  • Mention if the room is upstairs or in a flat
  • Mention any parking restrictions or tricky access
  • Tell us about any previous repairs or coatings

Different materials, different repairs

Shower trays

We put weight on a tray before sealing it, 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.

How we price bath resealing

We charge the same across the UK, including Northaw Valley. What changes the price is:

  • The material and finish
  • Any earlier repairs that need removing first
  • What kind of damage it is
  • Doing more than one item at once

A repair is priced on what needs doing, not where you live. You will see the full price before you book, with no extras added later.

Quotes from your pictures

Good photos mean an accurate price. Here’s what we find most useful:

  • Daylight if possible, and no flash reflection
  • Any details about the material
  • The postcode, so we can plan the visit
  • A coin or ruler next to the damage for scale

Call 0345 017 0787 or use the quote form. With a clear picture of the damage and one of the whole bath or shower, we can price the job without visiting.

DIY repairs versus a professional job

For a hairline mark somewhere you will never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

If you are set on a kit, follow its instructions closely, and don’t use it until it has fully cured. If it does not work out, we can still repair it properly.

Why it’s worth resealing in Northaw Valley

A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. Set against the cost of replacement, a repair is normally a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

What a repair cannot fix

Some jobs are not right for a repair, for example:

  • Movement in the bath or tray
  • Tiles that move, until they’re refixed
  • Gaps too big for silicone alone

Send us photos and we will tell you honestly.

Materials we repair

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

When to call us in Northaw Valley

No sealant lasts for ever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint flexes each time the bath fills.

Look out for these signs:

  • Black spots in the silicone
  • Unsealed corners
  • An untidy old seal
  • Silicone coming away from the tiles

What your quote should include

  • If travel is included in the price
  • What the guarantee covers, and for how long
  • What protection goes down before work starts
  • How the colour is matched
