Landlord and trade work in Dinorwig
We regularly price jobs from inventory or check-out photos. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.
We are used to working with agents and managing companies. Just send photos, the address and how to get access.
Should I try a DIY kit first?
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, then guarantee it for a year.
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and give it the full curing time. If it fails, we can still put it right.
Materials and what they mean for the repair
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Baths
We fill the bath before sealing, to open the joint fully.
How to care for the repair
It’s all simple stuff:
- Air the room after use
- Clean the sealant gently and regularly
- Use the extractor fan
- Dry the seal after bathing
Keep the room well ventilated, and wipe the joints after use to keep mould away.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
Resealing in Dinorwig: why it matters
Resealing is a small job. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send photos and you will get a fixed figure.
Why us?
- Honest advice, even when it means no job
- Same prices wherever you are
- Most jobs done in one visit

How the visit works
You don’t need to empty the room beforehand. We bring everything we need with us, lay protective sheets and start once you are happy with the plan. It normally takes around two hours, and you are welcome to carry on with your day while we work.
- We cut out all of the old sealant.
- 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.
Preparing for the visit

FAQs for Dinorwig
Is there a guarantee?
Yes: twelve months. If there’s a problem with the work in that time, we come back and put it right.
It’s been repaired before. Can you still fix it?
Most of the time. Let us know what was used before and we’ll plan for it.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Is there any odour?
Some materials have a smell while they’re applied, which is why we ventilate. It fades as everything cures.
Is it OK to have pets in the house?
We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.
Can new silicone go over old?
No, we never seal over old silicone. The old sealant is cut out and the joint cleaned and dried.
How do I stop mould in sealant?
Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
Will you leave a mess?
Dust sheets and masking go down before we start, and we clean up when we have finished.
