How we handle bath resealing in Gwernesney
All of the old sealant is cut out, treat any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. We work on baths, wet rooms and kitchen worktops & sinks, and the jobs we see most are silicone smeared on tiles and old sealant that looks dirty.
Your repair is guaranteed for a year, as with every job we do.

How it works
It’s a tidy, low-fuss visit. We confirm the time with you beforehand, protect the area, and get on with the job, which usually takes about two hours for a bath. If we find something your photos didn’t show, we’ll explain it before carrying on.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
Preparing for the visit
- Move bottles, mats and clutter away from the area
- Mention any parking restrictions or tricky access
- Keep children and pets away from the room on the day

Advice
For landlords and businesses
Hotels, guest houses and holiday lets need rooms back in use quickly, so we keep visits short and tidy. We can work around your bookings.
Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

Aftercare tips
So the finish stays in good condition:
- Don’t stand toiletries on the seal
- Ventilate the bathroom well
- Reseal when black spots won’t clean off
- Clean the joints with a mild cleaner
Avoid scraping the joints, and keep shampoo bottles off the joints.
Damp below or loose tiles need checking quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
Your questions about bath resealing in Gwernesney
Is a repair better than a new one?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we will tell you.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
My seal keeps tearing. Why?
Movement is the usual cause. We fill the bath before sealing it.
Are you a vetted contractor?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
Do I have to be there?
We need someone to let us in. After that, you can carry on with your day.
Is it OK to have pets in the house?
Yes, as long as they stay out of the room we are working in. We will let you know when it’s safe to use again.
Can you quote from pictures?
Yes, almost always. Clear pictures let us give you a fixed price without visiting.
Can new silicone go over old?
We always remove the old sealant completely. New silicone will not bond to old.
Different materials, different repairs
Shower trays
We put weight on a tray before sealing it, for the same reason.
Sinks and worktops

Should I try a DIY kit first?
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.
