Bath & shower resealing (mastic) in Rhiwlas, Gwynedd
We travel to Rhiwlas for bath, shower and sink resealing with new mould-resistant silicone. Nothing is taken out, and the work is guaranteed.

- Mould you can’t clean out
- A messy previous reseal
About our bath resealing in Rhiwlas
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, as one neat, continuous bead. If you are dealing with black mould in the sealant and gaps by the taps, we can usually put it right.
Big or small, it’s backed by a one-year guarantee in Rhiwlas and across Gwynedd.

How the visit works
Your technician turns up at the time we agreed with you and checks the damage against your photos first. The floor and nearby surfaces are covered before any work starts. Most visits take about two hours for a bath, and we leave the room as we found it.
- First we strip out every bit of the old mastic.
- Next we clean the joint and deal with mould.
- The joint is dried thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Getting ready for the visit
- Keep a parking space free if you can
- Have a window or extractor fan available
- Keep children and pets away from the room on the day

For landlords and businesses
We work for landlords, letting agents and housing providers in Rhiwlas as well as householders. A repair between tenants keeps the property empty for less time, and it costs much less than replacing.
We’re used to working with agents and managing companies. Send the address, photos and access details and we’ll handle the rest.
DIY repairs versus a professional job
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it does not stop a professional repair. Just mention it when you send photos, as it can add time.
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
Is resealing worth it?
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Send pictures and we’ll give you the exact figure.
Why book with us
- Nothing taken out or refitted
- One visit for most repairs
- Every repair guaranteed for a year
- A fixed quote before booking

How we price bath resealing
You will not pay by the hour. The price depends on:
- What kind of damage it is
- The material and finish
- How many items we do on one visit
- Unusual colours or finishes
Set against the cost of replacement, repairing typically costs far less, because there’s no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Getting a price from pictures
When you take your photos, these tips help us give you a firm price:
- One picture of the entire bath or shower
- Whether it’s been repaired or coated before
- Your postcode, so we can check dates
- The material, if you know it
There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we will come back to you with a fixed figure.
Rhiwlas questions
Are you accredited?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
How long does a reseal take?
Most reseals take about two hours. It then needs time to cure.
How much does bath resealing cost in Rhiwlas?
The exact price depends on the damage, so we quote from photos. You know the full cost before anything is booked.
How long does silicone take to cure?
We’ll give you the curing time.
Why does my sealant keep splitting?
The bath or tray is probably flexing. Persistent splitting can mean the support needs attention.
What happens next?
We come back with a fixed quote, usually with dates to choose from. There is no obligation to book.
When can you do it?
It depends on the time of year and where you are. Send pictures with your postcode and we will reply with the earliest dates.
Is repairing better than replacing?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
Different materials, different repairs
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Baths
We fill the bath before sealing, to open the joint fully.
Keeping it looking good
Most damage we see is avoidable. These habits help:
- Ventilate the bathroom well
- Let steam out after showers
- Dry the seal after bathing
- Reseal when black spots will not clean off
Leave the sealant to cure for the time we give you, usually around 24 hours.
Do not wait until water gets behind the bath. Gaps or lifting edges mean it needs doing.
What we’re called out for in Rhiwlas
Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all wear it down.
Typical reasons for a call-out include:
- An untidy old seal
- Discoloured, yellow sealant
- Black mould in the sealant
- Leaks at the edges
What your quote should include
- When it can be used again
- The length of the guarantee and what it covers
- Who will actually do the work
- Aftercare advice
