Resealing in Belsize: why it matters
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. The price reflects the work involved, not your postcode. You’ll see the full price before booking, with no extras added later.

- One-year guarantee on every repair
- No extra charge for your area
- Most jobs done in one visit

How we handle bath resealing in Belsize
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. Whether it’s missing sealant behind the taps and silicone smeared on tiles, we can help.
A one-year guarantee comes with the work, just as it does everywhere we cover.

When we would advise against a repair
Before you book, it’s worth knowing the limits too:
- Water damage behind the bath that needs a builder
- Tiles that move, until they’re refixed
- A flexing bath
If in doubt, send photos and we’ll say what we think before booking.
Surfaces we repair
- Basins & vanity units
- Baths
- Kitchen worktops & sinks
- Wet rooms
- Shower trays & enclosures
Keeping it looking good
After the repair has cured, a few habits help it last:
- Reseal at the first sign of lifting
- Don’t stand toiletries on the seal
- Give the seal a regular clean
- Dry the seal after bathing
Keep the room well ventilated, and wipe the joints after use to keep mould away.
Black mould in sealant isn’t just unsightly. An early reseal keeps water where it belongs.
Belsize: your questions answered
Does someone need to be in?
We need someone to let us in. After that, you can carry on with your day.
Can you repair several things at once?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
Is there any odour?
A little, depending on the job. Open windows and an extractor fan help, and it soon fades.
Is it safe with children and pets around?
Keep pets and children away from the work area on the day, mainly so nothing gets touched before it has cured.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
What happens once I’ve sent pictures?
We come back with a fixed quote. There is no obligation to book.
Why does the silicone keep cracking?
The bath or tray is probably flexing. Persistent splitting can mean the support needs attention.
How quickly can you book me in?
Your quote comes with available dates. If it’s urgent, say so and we’ll do what we can.

What bath resealing costs
We don’t charge extra for travel to Belsize. The price comes down to:
- How much damage there is
- What kind of damage it is
- Whether we combine several jobs
- Whether old repairs or coatings need taking off
Compared with replacing, a repair is generally a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.
Quotes from your pictures
We price nearly every job from photos. This is what we need:
- Any earlier repairs or coatings
- Something in shot to show the size
- Your postcode, so we can check dates
- Natural light rather than flash
For most jobs, pictures are all we need to give you a price. Add a line about what happened and your postcode, and we’ll send back a fixed quote and some dates.

What else we do in Belsize
Different materials, different repairs
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Baths
Baths are resealed with water in them, to open the joint fully.
What happens on the day
Your technician turns up when we said we would and looks over the damage before anything else. The floor and nearby surfaces are covered before any work starts. The work itself takes a couple of hours, and the room is left clean and tidy.
- First we strip out every bit of the old mastic.
- The joint is cleaned and any mould treated.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
Before we arrive
- Let the surface dry out before the visit
- Mention any parking restrictions or tricky access
- Keep pets and children out of the room while we work
How to get a price
The quickest way to a price is to send two or three photos through our quote form or ring us. We’ll say right away whether it can be repaired.
