Bath resealing in Llan Ffestiniog

Bath resealing in Llan Ffestiniog, done in place

The key to a good reseal is getting all of the old silicone out. New silicone will not bond to old, which is why so many DIY reseals peel. Common call-outs are for leaks at the edges and missing sealant behind the taps, in kitchen worktops & sinks, wet rooms and shower trays & enclosures.

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

DIY kit or professional repair?

It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is typically the cheaper route.

It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.

FAQs for Llan Ffestiniog

How do I book?

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

It’s been repaired before. Can you still fix it?

Typically, yes. We remove the old repair before doing a new one, so mention it when you send photos.

Why does my sealant keep splitting?

The bath or tray is probably flexing. If it keeps happening, the support may need fixing.

Is it safe with children and pets around?

Just keep them out of the work area. We will tell you when the room can be used again.

How do I stop mould in sealant?

Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.

I rent my home. Can I book you?

Of course. Check with your landlord; we can send the quote to them too.

Will the price change on the day?

If we find something the photos didn’t show, we explain it first. You decide whether to go ahead.

Is it worth repairing rather than replacing?

Usually, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.

What we’re called out for in Llan Ffestiniog

Sealant does not last forever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint flexes each time the bath fills.

It’s worth getting a quote if you see:

  • Gaps by the taps
  • Discoloured, yellow sealant
  • Silicone coming away from the tiles
  • Black mould in the sealant

Questions to ask before you book

  • How long it needs to cure
  • How the room is protected while they work
  • Whether the price covers travel
  • Who will actually do the work

Choosing a repair company

Honest limits

We will not take on work that will not last, so these are the limits:

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

Send us pictures and we’ll tell you honestly.

Materials we repair

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

How the visit works

Visits start with a quick look at the job together, so there are no surprises. Then the area is sheeted and masked and we start. Allow around two hours.

  1. The surrounding area is protected and the joints masked.
  2. Old sealant and residue are removed.
  3. We clean, treat and dry the joint.
  4. Fresh silicone is applied in a continuous bead.
  5. The bead is smoothed, the tape removed and the seal left to cure.

Before we arrive

  • Move bottles, mats and clutter away from the area
  • Avoid using the area for a few hours before we arrive
  • Keep pets and children out of the room while we work

Advice

Materials and what they mean for the repair

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.

Baths

Baths are resealed with water in them, to open the joint fully.

Aftercare tips

Most damage we see is avoidable. A few tips:

  • Air the room after use
  • Ventilate the bathroom well
  • Don’t stand toiletries on the seal
  • Reseal at the first sign of lifting

Avoid scraping the joints, and do not stand bottles on the seal.

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

Is resealing worth it?

Resealing is a small job. Leaving split or mouldy sealant lets water get behind the bath or tray, and that damage costs much more to fix. Compared with replacing, repairing generally costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.

What you get with us

  • Nothing taken out or refitted
  • Rooms protected and left tidy
  • Free fixed quotes from pictures
  • A year’s guarantee on all work
