Should I try a DIY kit first?
It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.
If you are set on a kit, follow its instructions closely and work on a clean, dry surface, and don’t use it until it has fully cured. If it does not work out, we can still repair it properly.

Keeping it looking good
How the surface is treated afterwards matters. Here’s what we suggest:
- Clean the sealant gently and regularly
- Ventilate the bathroom well
- Keep the joints dry
- Store bottles on a shelf
Keep the room well ventilated, and wipe the joints after use.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
Johnstown: your questions answered
How long before I can shower?
You’ll get the curing time from us, usually around a day.
Do the materials smell?
Some materials have a smell while they’re applied, which is why we ventilate. It clears as the materials cure.
How long does a reseal take?
Most reseals take about two hours. Leave it to cure before use.
What if the damage is worse than the photos show?
We will show you and explain before doing anything extra. Nothing extra is done without your say-so.
Do I need to be at home?
Yes. We need access to the room while we work, at a time we agree with you.
How do I stop mould in sealant?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Can you repair several things at once?
Of course, and it usually saves money. Just add the extra items to your pictures and you will get one combined price.
Can landlords book you?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses.
What affects the price in Johnstown

- We protect the area and mask the joint lines.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- We run a continuous bead of new silicone.
- The bead is smoothed, the tape removed and the seal left to cure.
