Bath resealing at your home in Cwm
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. Our technicians work on shower trays & enclosures, kitchen worktops & sinks and wet rooms, and people most often call us about silicone smeared on tiles and unsealed corners.
Every repair comes with a one-year guarantee, wherever you are in Swansea.

Can I fix it myself?
If you are 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.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is generally cheaper.
Prices and what affects them
We don’t charge extra for travel to Cwm. The price depends on:
- The material and finish
- How easy the damage is to reach
- How many items we do on one visit
- Any earlier repairs that need removing first
Our prices are the same across the UK, so there’s no premium for Cwm. What changes the price is the job itself: how much damage, what it’s made of and how many items.
How to get a fixed price
Almost every job we do is priced from pictures. This is what to send:
- A wider photo showing the entire bath or shower
- Natural light rather than flash
- Any details about the material
- A clear, close picture of the problem area
No survey visit is needed: we price from pictures. Use the quote form, or ring 0345 017 0787 to talk it through, and we’ll come back with a fixed figure.
The process
Once we are through the door, we keep the work contained to the one room. We mask off everything nearby, the work takes about two hours for a bath, and we finish by cleaning up and talking you through the result.
- First we strip out every bit of the old mastic.
- We clean the joint and treat any mould.
- We ensure the joint is completely dry.
- For a bath, we fill it with water first so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, including around the taps.
Before we arrive
- Move bottles, mats and clutter away from the area
- Open a window if you can
- Let us know which floor the room is on
Ask for a price
To get a price, send two or three photos through our quote form or call us. We will tell you honestly if a repair is the right fix.

Honest limits
Before booking, it’s worth knowing the limits:
- Tiles that move, until they’re refixed
- Gaps too big for silicone alone
- A bath or tray that moves, until its support is fixed
If in doubt, send photos and we will say what we think before booking.
Surfaces we repair
- Baths
- Shower trays & enclosures
- Basins & vanity units
- Kitchen worktops & sinks
- Wet rooms
What your bath or shower is made of matters
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Shower trays
We put weight on a tray before sealing it, for the same reason.

Aftercare tips
To keep it looking its best for years:
- Wipe the joints dry after use
- Let steam out after showers
- Reseal at the first sign of lifting
- Do not stand toiletries on the seal
Run the extractor fan, dry the joints after bathing, and give them a regular clean with a mild cleaner to slow mould growth.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Common problems we fix in Cwm
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
The most common problems we’re called about are:
- Leaks at the edges
- Mould you cannot clean out
- Unsealed corners
- Sealant that’s split or lifting

Work for landlords and builders
Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
If you manage property in Cwm, we can repair and quote for several addresses together. Just send photos for each address and we’ll come back with a combined price.
Cwm questions
Can you reseal over the old silicone?
Never over old. The old sealant is cut out and the joint cleaned and dried.
Can you repair several things at once?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
Do the materials smell?
It depends on the job, but often a little. Open windows and an extractor fan help.
Is the work guaranteed?
Every repair comes with our one-year guarantee. Ask us what it covers when you get your quote.
Do you charge for travel?
There’s no separate call-out charge. The fixed price covers the visit and the work.
Is it worth repairing rather than replacing?
In most cases, yes. A repair skips the removal, fitting and redecorating. If it isn’t worth repairing, we’ll tell you.
Can you quote from pictures?
Nearly always. We only ask to see it in person if the pictures can’t show what we need.
Is it OK to have pets in the house?
On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.
