Bath resealing in Mullion

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

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

Bath resealing in Mullion, done in place

Resealing is quick, but it transforms the look. Clean, white joints make a bathroom look cared for, and they keep water out. We are often asked to fix unsealed corners and stained silicone, in kitchen worktops & sinks, baths and shower trays & enclosures.

Your repair is guaranteed for a year, as with every job we do.

Mullion: your questions answered

How do I book?

Photos of the damage, a picture of the whole bath or shower and your postcode. Then we will agree a date.

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.

How soon can you come?

It depends on the time of year and where you are. We will offer you dates when we send your quote.

How long will it take?

Around two hours for a bath, plus curing time.

Are you a vetted contractor?

We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.

Is there a guarantee?

Every repair comes with a one-year guarantee. Ask us what it covers when you get your quote.

Why does the silicone keep cracking?

Movement is the usual cause. We seal baths full of water.

Can I get a quote without a visit?

Yes, almost always. A close-up and a wider photo are enough to give a fixed price.

Work for landlords and builders

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

For anyone letting property in or around Mullion, we will quote for several properties at once. Send pictures for each one and we’ll price them together.

Aftercare tips

To keep it looking its best for years:

  • Reseal when black spots won’t clean off
  • Keep the joints dry
  • Store bottles on a shelf
  • Use the extractor fan

Keep the room well ventilated, and wipe the joints after use to keep mould away.

Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

Do you need bath resealing in Mullion?

Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all take their toll.

Signs it’s time to call us include:

  • Gaps by the taps
  • Black mould in the sealant
  • Old sealant that looks dirty
  • Gaps in the seal

Questions to ask before you book

  • What protection goes down before work starts
  • Is the price fixed, and does it include VAT?
  • Who turns up on the day
  • How the colour is matched

How we price bath resealing

There’s no charge for travel to Mullion. The price depends on:

  • How many items we do on one visit
  • Access to the area
  • Whether it’s a chip, crack, burn or wear
  • How hard the colour is to match

We charge the same wherever you are, with no extra for Mullion. What changes the price is the job itself: how much damage, what it’s made of and how many items.

Send pictures for a quote

Phone pictures are fine, there is no need for anything special. Make sure they show:

  • Details of any past repairs
  • Good light, ideally daylight, without flash glare
  • A coin beside the damage so we can judge size
  • What it’s made of, if you know

We price from pictures so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through.

When we’d advise against a repair

Before you book, it’s worth knowing the limits too:

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

If in doubt, send pictures and we’ll say what we think before you book.

Materials we work on in Mullion

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

The process

A typical visit goes like this: we arrive at the agreed slot, protect everything around the work area, do the job and clear up. Allow around two hours. Before we go, we’ll explain how long to leave it and what to avoid for the first few days.

  1. We cut out and remove all of the old sealant.
  2. We clean the joint and treat any mould.
  3. The joint is dried thoroughly.
  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.

Before we arrive

  • Plan for the room to be out of bounds to pets and children
  • Avoid using the area for a few hours before we arrive
  • Tell us if there are stairs or a lift

How to get a price
