Trusted bath resealing in Sunderland

Bath resealing in Sunderland, done in place

Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, as one neat, continuous bead. We work on basins & vanity units, shower trays & enclosures and baths, and common reasons people contact us are damp near the bath and black spots in the silicone.

You are covered after we leave: our one-year guarantee applies to every job, and we explain what it covers before you book.

FAQs for Sunderland

Can you repair several things at once?

Yes. Doing several items on one visit usually costs less than separate visits. Include photos of each item.

Are there extra charges for Sunderland?

No. Our quotes include travel, and we charge the same wherever you are.

Can pets and children be at home?

Please keep children and pets out of the room during the visit. The rest of the house is unaffected.

My seal keeps tearing. Why?

Movement is the usual cause, or it was sealed with the bath empty. We seal baths full of water.

How do I stop mould in sealant?

Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.

Is it worth repairing rather than replacing?

In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.

Do you do work for letting agents?

Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses across Lancashire.

Do you seal over the old sealant?

All the old sealant comes out. New silicone will not bond to old.

Is resealing worth it?

Resealing is a small job. Putting off a reseal can let water reach the walls and floor, and that damage costs much more to fix. We charge the same wherever you are, with no extra for Sunderland. What changes the price is the job itself: how much damage, what it’s made of and how many items.

Signs you need bath resealing in Sunderland

Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint moves slightly every time the bath is filled.

Send us a picture if you notice any of these:

  • Sealant that’s split or lifting
  • Gaps by the taps
  • Stained silicone
  • An untidy old seal

Questions to ask before you book

  • Whether the price is fixed and includes VAT
  • How long it needs to cure
  • How changes to the job are handled
  • What prep work is covered

10 questions to ask before you book

Can I fix it myself?

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.

Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is usually cheaper.

Looking after it afterwards

Nothing complicated is needed:

  • Dry the seal after bathing
  • Keep bottles off the joints
  • Run the extractor fan during and after showers
  • Open a window after bathing

Good ventilation is the best protection, and wipe the joints after use 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.

Materials and what they mean for the repair

Shower trays

Trays are sealed with weight on them, for the same reason.

Baths

Baths are resealed with water in them, so the joint is at its widest.

What we do, step by step

When we visit, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. Expect it to take about two hours for a bath. We clean up when we are done and tell you when it’s ready to use.

  1. First we strip out every bit of the old mastic.
  2. Next we clean the joint and deal with mould.
  3. The joint is dried thoroughly.
  4. Baths are filled with water first, so the joint is at its widest.
  5. New mould-resistant silicone goes on and is tooled to a neat finish, taps included.

Preparing for the visit

  • Have a window or extractor fan available
  • Tell us about parking, stairs or access
  • Keep children and pets away from the room on the day
