Bath resealing near Clydach

What we cannot put right

We would rather lose a job than do one that will not last, so these are the limits:

  • Tiles that move, until they’re refixed
  • Gaps too big for silicone alone
  • Water damage behind the bath that needs a builder

Not sure? Send photos and we will give you a straight answer.

Surfaces we repair

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

Bath resealing in Clydach without replacing anything

A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they keep water out. If you’re dealing with black spots in the silicone and sealant that’s split or lifting, we can help, whatever the material.

You’re covered for a year from the day of the repair. Just call us if there is a problem and we’ll sort it.

How to look after the repair

Much of the damage we repair could have been avoided. These habits help:

  • Dry the seal after bathing
  • Reseal at the first sign of lifting
  • Let steam out after showers
  • Clean the sealant gently and regularly

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

Black mould in sealant is not just unsightly. An early reseal keeps water where it belongs.

How it works

Your technician turns up at the time we agreed with you, introduces themselves and looks over the damage before anything else. Dust sheets and masking tape go down before we open a single tin. Most visits take around two hours, and we leave the room as we found it.

  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. The bath is filled with water, or weight put on the tray.
  5. New mould-resistant silicone is applied and tooled neatly.

Getting ready for the visit

  • Mention any earlier repairs or resurfacing
  • Tell us about parking, stairs or access
  • Have somewhere for us to park nearby if possible

Related advice

Can I fix it myself?

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 normally the cheaper route.

What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.

Is resealing worth it?

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. The price depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. You get a fixed price from your photos, so you know the cost before you book.

What you get with us

  • Generally one visit, start to finish
  • A fixed quote before booking
  • Rooms protected and left tidy

Questions from Clydach

Do you hold any accreditations?

We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.

Why does my sealant keep splitting?

Typically because the bath or tray moves. We fill the bath before sealing it.

Do the materials smell?

Expect a mild smell while we are working.

Is repairing better than replacing?

Typically, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.

Can you quote from pictures?

Nearly always. If photos don’t show enough, we’ll ask for another angle.

Can you reseal over the old silicone?

No, we never seal over old silicone. The old sealant is cut out and the joint cleaned and dried.

How do I book?

A close-up, a wider photo and your postcode. After that, we just agree a date.

What if the damage is worse than the pictures show?

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

What bath resealing costs

We don’t charge extra for travel to Clydach. The price depends on:

  • How much damage there is
  • The type of damage
  • Doing more than one item at once
  • Access to the area

Every job is a little different, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.

Quotes from your pictures

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

  • Any earlier repairs or coatings
  • The material, if you know it
  • Natural light rather than flash
  • A clear, close picture of the problem area

Email us a photo of the damage and one of the whole item, with your SA6 postcode, and we’ll come back with a fixed quote.

Different materials, different repairs

Baths

We fill the bath before sealing, to open the joint fully.

Sinks and worktops

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

For landlords and businesses

We regularly price jobs from inventory or check-out photos. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.

If you manage property in Clydach, we’ll quote for several properties at once. Just send pictures for each address and we’ll price them together.
