How we handle bath resealing in Letchmore Heath
A proper reseal starts with removing every trace of the old silicone. New silicone won’t bond to old, which is why so many DIY reseals peel. Common call-outs are for sealant that’s split or lifting and black spots in the silicone, across baths, wet rooms and kitchen worktops & sinks.
We stand behind the work with a one-year guarantee, so you are not left on your own once we’ve gone.

Letchmore Heath questions
What happens next?
You get a fixed quote and available dates. If anything’s unclear, we’ll ask for another photo.
Can pets and children be at home?
Keep pets and children away from the work area on the day.
Can you repair several things at once?
Of course, and it typically saves money. Just add the extra items to your photos and we will quote them together.
Can tenants book a repair?
Of course. Check with your landlord; we can send the quote to them too.
How do I book?
Use the quote form or ring 0345 017 0787, and we will do the rest.
How much does bath resealing cost in Letchmore Heath?
Every job gets a fixed quote from your photos. Send a close-up and a photo of the entire item and your postcode.
Is there any odour?
Expect a mild smell while we are working that clears as it cures.
Why does my sealant keep going mouldy?
Typically poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.
DIY repairs versus a professional job
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
What happens on the day
We agree an arrival time beforehand, so you know when to expect us. On site, it takes about two hours for a bath for most jobs. We leave the room clean.
- All the old sealant is cut out and removed.
- Next we clean the joint and deal with mould.
- We dry the joint thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, taps included.
Preparing for the visit
- Clear toiletries, mats and anything else from around the area
- Ensure the room can be ventilated
- Tell us about parking, stairs or access
Ask for a price
The quickest way to a price is to send a couple of pictures through our quote form or call us. We will say immediately if a repair is the right fix.

When a repair is not the answer
In fairness, some problems need a different fix:
- Rotten walls or floors behind the bath
- Gaps too big for silicone alone
- Tiles that move, until they’re refixed
If in doubt, send photos and we will say what we think before you book.

Do you need bath resealing in Letchmore Heath?
Black mould is the most common reason people reseal. It grows into the sealant itself, so cleaning only removes the surface.
Typical reasons for a call-out include:
- An untidy old seal
- Stained silicone
- Gaps in the seal
- Gaps by the taps
What to look for in a quote
- When it can be used again
- What happens if they find more damage
- How to look after the finish
- Who will actually do the work
Looking after it afterwards
Looking after the surface is easy, and it makes a real difference:
- Do not stand toiletries on the seal
- Give the seal a regular clean
- Reseal when black spots won’t clean off
- Run the extractor fan during and after showers
Run the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.

Resealing in Letchmore Heath: why it matters
Resealing is a small job. Leaving split or mouldy sealant lets water get behind the bath or tray, and that damage costs much more to fix. No two jobs are quite the same, so each one is priced on its own. 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.
