Bath, shower and sink resealing with new mould-resistant silicone at your home in Caernarfon, with a one-year guarantee on every repair.

For landlords and businesses
Hospitality businesses cannot afford rooms out of action for long, so most of our work is done in a single visit. We will fit around changeovers where we can.
Landlords, letting agents and housing providers in Caernarfon use us as well as homeowners. A repair between tenants keeps the property empty for less time, and it typically costs far less than a refit.
About our bath resealing in Caernarfon
A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. Whether it’s a messy previous reseal and discoloured, yellow sealant, we can generally put it right, on baths, basins & vanity units and wet rooms alike.
We stand behind the work with a one-year guarantee, so you’re covered after the visit.

The process
It’s a tidy, low-fuss visit. We confirm the time with you beforehand, protect the area, and get on with the job, which normally takes about two hours for a bath. If we find something your photos didn’t show, we’ll explain it before carrying on.
- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- The joint is dried thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, taps included.
Preparing for the visit
- Point us to the nearest place to park
- Let the surface dry out before the visit
- Mention if the room is upstairs or in a flat

Most clients in Caernarfon get their price from photos. Add a line about what happened and your postcode, and we’ll reply with a fixed quote and the earliest dates we have.
Advice
Repairs by material
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Prices and what affects them
Every quote is fixed and free. What we look at:
- How many areas need work
- Whether old repairs or coatings need taking off
- What the surface is made of
- The colour and finish to match
Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.
How to get a fixed price
Before you send pictures, these tips help us give you a firm price:
- The postcode, so we can plan the visit
- Any details about the material
- A close-up of the damage, in focus
- Natural light rather than flash
Send us a picture of the damage and one of the whole item, and tell us you are in Caernarfon, and we’ll reply with a fixed price.
Keeping it looking good
Most damage we see is avoidable. A few tips:
- Use the extractor fan
- Wipe the joints dry after use
- Replace the seal when mould sets in
- Do not stand toiletries on the seal
Do not scrape the sealant with anything sharp, and don’t stand bottles on the seal.
Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
Caernarfon: your questions answered
Are you accredited?
We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
What do you need from me?
Send pictures through the quote form or call 0345 017 0787, and we will do the rest.
Can you do more than one item on the same visit?
Yes, and it’s often cheaper. Just add the extra items to your photos and we’ll quote them together.
Is it worth repairing rather than replacing?
Normally, if the item is otherwise sound. A repair avoids removal and making good. We’ll tell you honestly if replacement makes more sense.
What does bath resealing cost?
Every job gets a fixed quote from your pictures. Send a close-up of the damage and a wider photo and your postcode.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Why does mould come back so fast?
Damp is the cause. Ventilation and drying keep it clean longer.
How quickly can you book me in?
We’ll give you dates with your quote. Tell us if you need it done quickly.

What we cannot put right
Not everything can be repaired, and we’ll tell you before we start. Repairs won’t solve:
- Loose tiles, which need refixing first
- Rotten walls or floors behind the bath
- Gaps so wide they need filling or trims before sealing
Send us photos and we’ll tell you honestly before you book.
Materials we repair
- Wet rooms
- Kitchen worktops & sinks
- Basins & vanity units
- Baths
- Shower trays & enclosures
DIY kit or professional repair?
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it does not work out, we can still repair it properly.
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.
Signs you need bath resealing in Caernarfon
Sealant splits when the bath or tray moves, often because it was sealed while the bath was empty.
