Your questions about bath resealing in Harmston
Is it safe with children and pets around?
Please keep children and pets out of the room during the visit and until it has cured. The rest of the house is unaffected.
Why does my sealant keep going mouldy?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
Will the price change on the day?
If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
Why does the silicone keep cracking?
Typically because the bath or tray moves, or it was sealed with the bath empty. We seal baths full of water.
How long does resealing take?
Generally a couple of hours, then it needs to cure.
Is the work guaranteed?
Every repair comes with a one-year guarantee. Ask us what it covers when you get your quote.
Do you come to Harmston?
Yes. We cover the whole UK and travel to Harmston and the rest of Lincolnshire. Send photos and we will quote, or call 0345 017 0787.
Can you reseal over the old silicone?
Never over old. It’s removed, cleaned off and the joint dried first.
About our bath resealing in Harmston
The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why many DIY jobs peel. We work on shower trays & enclosures, wet rooms and baths, and the jobs we see most are black mould in the sealant and unsealed corners.
Every job is backed for twelve months in Harmston and everywhere else. We return to put right any problem with the work.

How we price bath resealing
We give every job a fixed price from pictures. This is what makes a difference:
- Whether we combine several jobs
- Where the damage is and how we get to it
- How many areas need work
- What kind of damage it is
We charge the same wherever you are, so there’s no premium for Harmston. The job itself decides the price: the material, the amount of damage and how many items.
How to get a fixed quote
Most quotes are done from photos alone. To make it quick:
- Natural light rather than flash
- Whether it’s been repaired or coated before
- One sharp close-up of the damage
- Your postcode, so we can check dates
To get a price, send a couple of photos through our quote form or ring us. We’ll say right away if a repair is the right fix.
Landlords, agents and businesses in Harmston
We also carry out snagging repairs for builders and developers, putting right damage done during fitting. We are CHAS, Constructionline and SafeContractor accredited.
For developers and builders, we fix damage before handover, saving last-minute replacements. Several plots can be done in one visit.
Should I try a DIY kit first?
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. It does add a little time, so tell us about it when you send pictures.
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair will not last.
Resealing in Harmston: 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. Set against the cost of replacement, repairing generally costs far less, because there is no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Why us?
- Work done at your home or business
- Every repair guaranteed for a year
- No need to remove anything
- Rooms protected and left tidy
