Bath resealing near Llanbedr

Bath resealing in Llanbedr without replacing anything

A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, as one neat, continuous bead. Typical jobs include gaps by the taps and silicone smeared on tiles, on basins & vanity units, shower trays & enclosures and kitchen worktops & sinks.

You are covered for a year from the day of the repair. If anything is not right, ring us and we will come back.

For landlords and businesses

Builders use us to fix snagging damage before handover, so there is no need to replace a damaged item at the last minute. Several plots can be done in one visit to keep costs down.

Hospitality businesses can’t afford rooms out of action for long, so most of our work is done in a single visit. We can work around your bookings.

Can I fix it myself?

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

The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.

Prices and what affects them

We price every job individually, from your photos. The main factors are:

  • How many items we do on one visit
  • How much damage there is
  • The material and finish
  • Whether old repairs or coatings need taking off

Instead of hourly rates, we price the whole job up front. Damage, material and access decide it, and doing several items at once reduces it.

Quotes from your pictures

When you take your pictures, a few simple things make all the difference:

  • A coin beside the damage so we can judge size
  • The postcode, so we can plan the visit
  • What it’s made of, if you know
  • Any earlier repairs or coatings

There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed price.

Signs you need bath resealing in Llanbedr

Even good sealant eventually discolours particularly in a well-used bathroom. Steam, soap and movement all take their toll.

You may need us if you’ve spotted any of these:

  • Discoloured, yellow sealant
  • Unsealed corners
  • Mould you can’t clean out
  • Leaks at the edges

What your quote should include

  • How your room will be protected
  • How changes to the job are handled
  • What preparation is included
  • Who will actually do the work

How to compare quotes

Aftercare tips

Once the work has cured, treat it gently:

  • Don’t stand toiletries on the seal
  • Reseal when black spots will not clean off
  • Dry the seal after bathing
  • Give the seal a regular clean

Keep the room well ventilated, and dry the joints after bathing so mould struggles to take hold.

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

When a repair is not the answer

Honesty matters more than a booking, so here’s what a repair will not do:

  • Water damage behind the bath that needs a builder
  • Loose tiles, which need refixing first
  • Gaps so wide they need filling or trims before sealing

Send us pictures and we will tell you honestly.

Materials we repair

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

What happens on the day

On the day itself, there is little for you to do. Show us the job, point us to the room, and we will get on with it. Most visits take a couple of hours, including clearing up.

  1. The old silicone is cut out completely.
  2. Residue is removed and the joint cleaned.
  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.

Before we arrive

  • Clear the area around the damage
  • Let us know if it has been repaired before
  • Mention if the room is upstairs or in a flat

Keep pets and children away from the work area on the day, mainly so nothing gets touched before it has cured.

Materials and what they mean for the repair

Baths

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