Bath & shower resealing (mastic) in Pentrefelin, Gwynedd
Bath, shower and sink resealing with new mould-resistant silicone in Pentrefelin, carried out at your home and guaranteed for a year.
- Stained silicone
- Silicone smeared on tiles
- Unsealed corners
Can I fix it myself?
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send photos.
You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
Bath resealing in Pentrefelin without replacing anything
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and a new seal stops it. Common call-outs are for silicone smeared on tiles and stained silicone, across baths, wet rooms and shower trays & enclosures.
Whatever the size of the job, you get the same one-year guarantee.

- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.

Why it’s worth resealing in Pentrefelin
Resealing is routine maintenance. Putting off a reseal can let water reach the walls and floor, which costs far more to put right. The price depends on the type and amount of damage, what it’s made of and how many items we do on one visit. We give a fixed price from your pictures, so there are no surprises on the day.
What you get with us
- Dust sheets down, tidy finish
- Nothing taken out or refitted
- Every repair guaranteed for a year
- Accredited with CHAS, Constructionline and SafeContractor

Questions from Pentrefelin
Is it messy?
Dust sheets and masking go down before we start, and we clean up when we’ve finished.
How do I stop mould in sealant?
Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
Can you redo someone else’s repair?
Yes, we frequently do. Removing the old work can add time, and that’s in the quote.
Is there a call-out fee?
We do not add a call-out fee. Your fixed quote includes everything.
How long will it take?
Generally a couple of hours, then it needs to cure.
Is it safe with children and pets around?
On the day, the room should be kept clear of pets and children, so the repair is not disturbed while it cures.
Are you a vetted contractor?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Do you come to Pentrefelin?
Yes. We work across the UK and come to Pentrefelin. Send pictures and we will quote, or call 0345 017 0787.
