Bath resealing at your home in St John's Wood
The key to a good reseal is getting all of the old silicone out. New silicone will not bond to old, which is why so many DIY reseals peel. Our technicians work on kitchen worktops & sinks, shower trays & enclosures and basins & vanity units, and people most often call us about black mould in the sealant and leaks at the edges.
Whatever the size of the job, you get the same one-year guarantee.

DIY repairs versus a professional job
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
A DIY attempt is not a disaster. We remove the old filler and start again, so it does not stop a professional repair. Just mention it when you send photos, as it can add time.
Keeping it looking good
Most damage we see is avoidable. A few tips:
- Air the room after use
- Clean the sealant gently and regularly
- Replace the seal when mould sets in
- Use the extractor fan
Good ventilation is the best protection, and dry the joints after bathing.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
FAQs for St John's Wood
Is it worth repairing rather than replacing?
Generally, yes. A repair skips the removal, fitting and redecorating. We will be honest if it’s not worth it.
Can you reseal over the old silicone?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
How long does silicone take to cure?
You’ll get the curing time from us.
Will it make a mess?
Dust sheets and masking go down before we start, and tidy up before we leave.
What happens once I’ve sent pictures?
We review the pictures and send a fixed quote.
Do you work in St John's Wood?
We do. Technicians travel to St John's Wood from across the region, with no extra charge for travel.
Is it safe with children and pets around?
Keep pets and children away from the work area on the day, so the repair isn’t disturbed while it cures.
Do the materials smell?
There may be a mild smell during the work that clears as it cures.
Work for landlords and builders
We regularly work with letting and managing agents. Send the address, pictures and access details and we’ll handle the rest.
We carry out planned and one-off repairs for housing associations and facilities teams in Greater London and across the UK. Repairing in place avoids the disruption of a replacement, which is easier on the people living there.
Prices and what affects them
There is no area surcharge for St John's Wood. What changes the price is:
- Previous DIY repairs that have to come out
- Doing more than one item at once
- What the surface is made of
- How hard the colour is to match
There are no surprise extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
Send pictures for a quote
Almost every job we do is priced from pictures. This is what to send:
- A wider photo showing the entire bath or shower
- A clear, close picture of the problem area
- Where you are, by postcode
- Any earlier repairs or coatings
No survey visit is needed: we price from photos. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and you’ll get a fixed figure back.
What your bath or shower is made of matters
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
Baths
Baths are resealed with water in them, to open the joint fully.
How it works
You don’t need to empty the room beforehand. Everything we use comes in the van with us, put protection down and start once you’re happy with the plan. Most jobs take about two hours for a bath, and you’re welcome to carry on with your day while we work.
- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
Preparing for the visit
- Move bottles, mats and clutter away from the area
- Point us to the nearest place to park
- Mention any earlier repairs or resurfacing

Getting a quote takes a couple of minutes: take one close-up and one wider shot of the bath or shower, include your postcode and send them over. What comes back is a fixed quote, not a guess.
