About our bath resealing in Londonderry
The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why so many DIY reseals peel. Whether it’s stained silicone and damp near the bath, we can help.
You’re covered after we leave: our one-year guarantee applies to every job, and we will explain exactly what it covers when we quote.

Common questions in Londonderry
Do I have to be there?
We need someone to let us in. You don’t need to watch us work.
Do you do work for letting agents?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses in Londonderry.
Do you work in Londonderry?
Yes. We cover the whole UK and come to Londonderry and the rest of Derry. Send us photos for a fixed quote, or call 0345 017 0787.
Do you seal over the old sealant?
We always remove the old sealant completely. Fresh silicone does not stick to old.
How long does silicone take to cure?
We’ll give you the curing time, generally around a day.
It’s been repaired before. Can you still fix it?
Yes, we frequently do. Removing the old work can add time, and that is in the quote.
Is there any odour?
Some materials have a smell while they’re applied, so we ventilate the room. It fades as everything cures.
What happens next?
We check the damage, the material and your postcode, then reply with a quote with dates.
Landlord and trade work in Londonderry
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
Landlords, letting agents and housing providers in Londonderry use us as well as homeowners. A repair between tenants keeps the property empty for less time, and it generally costs far less than a refit.
How we price bath resealing
We charge the same across the UK, including Londonderry. The price reflects:
- What the surface is made of
- Any earlier repairs that need removing first
- The size and number of damaged areas
- Unusual colours or finishes
Set against the cost of replacement, a repair is typically a fraction of the price, because there’s no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Quotes from your photos
You can usually get a fixed quote without us visiting. To make it quick:
- A close-up of the damage, in focus
- Any earlier repairs or coatings
- Something in shot to show the size
- The postcode, so we can plan the visit
Getting a quote takes a couple of minutes: photograph the damage, then the whole bath or shower, add your postcode and send them over. What comes back is a fixed quote, not a guess.
How the visit works
Once we are through the door, we keep the work contained to the one room. We mask off everything nearby, the work takes a couple of hours, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- The old silicone is cut out completely.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Before we arrive
- Mention any earlier repairs or resurfacing
- Mention if the room is upstairs or in a flat
- Let us know about parking or access
Getting a price
If you’re in Londonderry and want a price, the easiest route is pictures: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.
Related advice
Can I fix it myself?
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and do not use it until it has fully cured. If it doesn’t work out, we can still repair it properly.
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
Keeping it looking good
To keep it looking its best for years:
- Open a window after bathing
- Ventilate the bathroom well
- Clean the joints with a mild cleaner
- Store bottles on a shelf
Good ventilation is the best protection, and wipe the joints after use so mould struggles to take hold.
Damp below or loose tiles need checking quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
Is resealing worth it?
Putting new silicone over old does not last. It peels within weeks, and mould stays trapped behind it. A proper reseal removes the old first. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send photos and we will give you the exact figure.
