Bath Resealing in North Harrow
Our repair technicians come to North Harrow for bath, shower and sink resealing with new mould-resistant silicone. Everything is done in place, and the work is guaranteed.
- Discoloured, yellow sealant
- Damp near the bath
- Gaps in the seal
What we can’t put right
We will not take on work that won’t last, so these are the limits:
- Gaps too big for silicone alone
- Water damage behind the bath that needs a builder
- Tiles that move, until they’re refixed
Not sure? Send photos and we will give you a straight answer before you book.

About our bath resealing in North Harrow
A fresh seal protects your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. If you are dealing with water getting behind the bath or tray and silicone coming away from the tiles, we can help, on wet rooms, shower trays & enclosures and baths alike.
We guarantee the work for a year. If there’s a problem with the repair within the year, we return and sort it.

Should I try a DIY kit first?
For a hairline mark somewhere you’ll never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it won’t stop us repairing it. It does add a little time, so tell us about it when you send photos.
Different materials, different repairs
Baths
We fill the bath before sealing, to open the joint fully.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
What we are called out for in North Harrow
Poor ventilation speeds things up: moisture sits on the joints longer, and mould takes hold.
Keep an eye out for any of the following:
- Gaps by the taps
- Stained silicone
- Sealant that is split or lifting
- Damp near the bath
What to look for in a quote
- Whether the price is fixed and includes VAT
- When it can be used again
- What protection goes down before work starts
- Whether cleaning and preparation are in the price
What happens on the day
There is not much you need to do on the day. Show us the job, point us to the room, and we’ll take it from there. The job generally runs to a couple of hours, tidy-up included.
- 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.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
How to prepare
- Keep pets and children out of the room while we work
- Tell us about any previous repairs or coatings
- Open a window if you can

North Harrow questions
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time that suits you.
Why does mould come back so fast?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
Can new silicone go over old?
We always remove the old sealant completely. Fresh silicone does not stick to old.
Do you do work for letting agents?
Yes. We work for landlords, agents, builders and businesses as well as homeowners.
Is it safe with children and pets around?
Please keep children and pets out of the room during the visit. The rest of the house is unaffected.
How long does a reseal take?
Most reseals take about two hours. Leave it to cure before use.
What do you need from me?
A close-up, a wider photo and your postcode. After that, we just agree a date.
Do you cover the whole of Greater London?
All of Greater London, and the rest of the UK. Travel is included in the price.
Keeping it looking good
Simple care helps the repair last. We recommend:
- Replace the seal when mould sets in
- Let steam out after showers
- Wipe the joints dry after use
- Clean the sealant gently and regularly
Run the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Damp below or loose tiles need checking quickly. There may be more going on, and we’ll say if you need a builder or plumber.
How we price bath resealing
Every quote is fixed and free. What we look at:
- The material and finish
- How easy the damage is to reach
- How many items we do on one visit
- Any earlier repairs that need removing first
A repair usually costs much less than people expect, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.
Getting a price from photos
Photographing the damage takes a minute, and it saves a visit. Try to send:
- A coin or ruler next to the damage for scale
- Details of any past repairs
- One picture of the entire bath or shower
- Where you are, by postcode
For a price in North Harrow, pictures are the quickest way: a close-up, a wider shot and your postcode. You will get a fixed quote with dates to choose from.
Resealing in North Harrow: why it matters
Resealing costs very little, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. No two jobs are quite the same, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and combining jobs on one visit brings the cost down.
