Bath resealing at your home in Northwick
The key to a good reseal is getting all of the old silicone out. Fresh sealant doesn’t stick to old, which is why so many DIY reseals peel. Whether it’s sealant that’s split or lifting and black spots in the silicone, we can help.
You get a one-year guarantee, the same in Northwick as everywhere else we work.

How we price bath resealing
We don’t charge extra for travel to Northwick. The price depends on:
- Access to the area
- What kind of damage it is
- Any earlier repairs that need removing first
- What the surface is made of
Compared with replacing, a repair is generally a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.
Send pictures for a quote
You can take the photos on your phone, there’s no need for anything special. Ensure they show:
- A close-up of the damage, in focus
- Whether it’s been repaired or coated before
- A photo taken from further back
- 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 will reply with a fixed quote and the earliest dates we have.
Why reseal now?
Resealing costs very little and protects the walls and floor. Failed sealant can lead to water damage that is much more expensive. Our prices are the same across the UK, so there’s no premium for Northwick. The job itself decides the price: the material, the amount of damage and how many items.
Why us?
- A year’s guarantee on all work
- CHAS and Constructionline accredited
- One price list for the entire UK
- No need to remove anything

DIY kit or professional repair?
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
Looking after it afterwards
How the surface is treated afterwards matters. Here’s what we suggest:
- Clean the joints with a mild cleaner
- Keep the joints dry
- Run the extractor fan during and after showers
- Reseal at the first sign of lifting
Avoid scraping the joints, and keep shampoo bottles off the joints.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.

FAQs for Northwick
Why does mould come back so fast?
Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.
Is it OK to have pets in the house?
Just keep them out of the work area. We’ll tell you when the room can be used again.
What happens if you find more damage?
If we find something the photos didn’t show, we explain it first. You decide whether to go ahead.
What happens after I send pictures?
We come back with a fixed price, plus dates. There’s no obligation to book.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Include pictures of each item.
Will you leave a mess?
No. The work area is masked and covered, and we take our waste away with us.
My seal keeps tearing. Why?
Typically because the bath or tray moves. We fill the bath before sealing it.

Hospitality businesses cannot afford rooms out of action for long, so most of our work is done in a single visit. We’ll fit around changeovers where we can.
