What affects the price in Gwaun Treoda
You’ll know the full cost before you book. We look at:
- Where the damage is and how we get to it
- What kind of damage it is
- What the surface is made of
- How hard the colour is to match
Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access.
Quotes from your pictures
When you take your pictures, these tips help us give you a firm price:
- Something in shot to show the size
- Any earlier repairs or coatings
- One sharp close-up of the damage
- One picture of the entire bath or shower
Email us a picture of the damage and one of the entire item, and tell us you are in Gwaun Treoda, and we will come back with a fixed quote.
Can I fix it myself?
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
Materials and what they mean for the repair
Baths
Baths are resealed with water in them, to open the joint fully.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
What happens on the day
Nothing needs to be moved out of the room. Everything we use comes in the van with us, put protection down and get going once we have agreed what we’re doing. Most jobs take about two hours for a bath, and you’re welcome to carry on with your day while we work.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Getting ready for the visit
- Ensure the room can be ventilated
- Clear the area around the damage
- Tell us about any previous repairs or coatings
Ask for a price
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them to us. You’ll get a fixed price, not an estimate.
Related advice
Signs you need bath resealing in Gwaun Treoda
Sealant splits when the bath or tray moves, often because it was sealed while the bath was empty.
Keep an eye out for any of the following:
- An untidy old seal
- Old sealant that looks dirty
- Mould you can’t clean out
- Gaps in the seal
What your quote should include
- Who turns up on the day
- How to look after the finish
- How changes to the job are handled
- How long it needs to cure
Keeping it looking good
How the surface is treated afterwards matters:
- Clean the sealant gently and regularly
- Keep the joints dry
- Reseal at the first sign of lifting
- Keep bottles off the joints
Use 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.
