Bath resealing in Northaw without replacing anything
A reseal is a small job that makes a big difference. Fresh joints make the whole room look cleaner, and they keep water out. If you’re dealing with sealant that’s split or lifting and mould you can’t clean out, we can help.
You’re covered after we leave: our one-year guarantee applies to every job, and we explain what it covers before booking.

DIY kit or professional repair?
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
Northaw: your questions answered
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone does not stick to old.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often glad to have it sorted.
What happens next?
We come back with a fixed price. There’s no obligation to book.
How long does silicone take to cure?
Typically after around 24 hours. We confirm before we leave.
Is there any odour?
Some materials have a smell while they’re applied, which is why we ventilate. It clears as the materials cure.
Can landlords book you?
Yes. We work for landlords, agents, builders and businesses as well as homeowners across Hertfordshire.
Why does my sealant keep splitting?
Usually because the bath or tray moves. We seal baths full of water.
Which areas do you work in?
Across the UK. Our prices are the same everywhere.
Why it’s worth resealing in Northaw
Putting new silicone over old doesn’t last. It soon peels, and traps mould underneath. We remove the old sealant completely. Instead of hourly rates, we fix the price before we start. It depends on the damage, the material and access.

Looking after it afterwards
Once the work has cured, treat it gently:
- Use the extractor fan
- Give the seal a regular clean
- Air the room after use
- Do not stand toiletries on the seal
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
Work for landlords and builders
We regularly work with letting and managing agents. Send the address, photos and access details and we will arrange it.
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.
What bath resealing costs
We give every job a fixed quote from photos. These are the things that affect it:
- What kind of damage it is
- What the surface is made of
- Any earlier repairs that need removing first
- Where the damage is and how we get to it
What it costs depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. We give a fixed quote from your photos, so there are no surprises on the day.
Quotes from your photos
The better the pictures, the more accurate the price. Here’s what we find most useful:
- What it’s made of, if you know
- A wider photo showing the whole bath or shower
- Any earlier repairs or coatings
- Where you are, by postcode
Most clients in Northaw get their price from photos. Add a line about what happened and your postcode, and we’ll send back a fixed quote and some dates.

Advice
What we can’t put right
We would rather lose a job than do one that will not last, so here’s what a repair cannot put right:
- Tiles that move, until they’re refixed
- Hidden water damage
- Very wide gaps that need a trim
Send us pictures and we will tell you honestly before booking.
