Bath & shower resealing (mastic) in Chwilog, Gwynedd
Bath, shower and sink resealing with new mould-resistant silicone at your home in Chwilog, with a one-year guarantee on every repair.
- Gaps by the taps
- Black mould in the sealant
- A messy previous reseal
DIY repairs versus a professional job
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is typically the cheaper route.
How we handle bath resealing in Chwilog
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, as one neat, continuous bead. We work on baths, shower trays & enclosures and wet rooms, and people most often call us about gaps in the seal and old sealant that looks dirty.
The work is guaranteed for twelve months. If something is not right in that time, we come back and put it right.

FAQs for Chwilog
What does bath resealing cost?
Because every job differs, we price from pictures. You know the full cost before anything is booked.
What if the damage is worse than the photos show?
The price is fixed for what the pictures show. If there is more, we’ll tell you before starting.
How soon can you come?
Your quote comes with available dates. Tell us if you need it done quickly.
Why does mould come back so fast?
Mould needs moisture. Ventilation and drying keep it clean longer.
What happens after I send pictures?
We review the pictures and send a fixed quote and the next dates we have.
What do you need from me?
A close-up, a wider photo and your postcode. Then we’ll agree a date.
Are you accredited?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Looking after it afterwards
After the repair has cured, a few habits help it last:
- Replace the seal when mould sets in
- Run the extractor fan during and after showers
- Clean the sealant gently and regularly
- Air the room after use
Keep the room well ventilated, and wipe the joints after use.
Don’t wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
Prices and what affects them
There is no charge for travel to Chwilog. The price depends on:
- The material and finish
- Unusual colours or finishes
- Whether old repairs or coatings need taking off
- How many areas need work
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 doing several things on one visit costs less than separate visits.
Quotes from your photos
You can usually get a fixed price without us visiting. To help us price it:
- Where you are, by postcode
- Any details about the material
- A wider photo showing the whole bath or shower
- One sharp close-up of the damage
To get a price, send a couple of photos using our quote form or call us. We’ll say immediately if a repair is the right fix.
When to call us in Chwilog
Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all wear it down.
The most common problems we’re called about are:
- Silicone coming away from the tiles
- Gaps by the taps
- Discoloured, yellow sealant
- Silicone smeared on tiles
What your quote should include
- Is the price fixed, and does it include VAT?
- How your room will be protected
- Whether the price covers travel
- Whether cleaning and preparation are in the price
