Bath resealing in Knightsmill, done in place
A proper reseal starts with removing every trace of the old silicone. New silicone will not bond to old, which is why many DIY jobs peel. We’re frequently asked to fix old sealant that looks dirty and silicone smeared on tiles, in shower trays & enclosures, basins & vanity units and wet rooms.
We stand behind the work with a one-year guarantee, so you are not left on your own once we’ve gone.

How we price bath resealing
You won’t pay by the hour. The price depends on:
- How many items we do on one visit
- Whether old repairs or coatings need taking off
- The material and finish
- The size and number of damaged areas
Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
Quotes from your pictures
Good photos mean an accurate price. Here’s what helps:
- A wider photo showing the whole bath or shower
- Whether it’s been repaired or coated before
- A coin beside the damage so we can judge size
- Good light, ideally daylight, without flash glare
You don’t need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed price.
What happens on the day
Visits start with a quick look at the job together. After that, protection goes down around the work area and we start. You can expect it to take about two hours for a bath, and we’ll tell you if anything changes.
- First we strip out every bit of the old mastic.
- We clean the joint and treat any mould.
- We dry the joint thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Getting ready for the visit
- Mention any parking restrictions or tricky access
- Mention any earlier repairs or resurfacing
- Point us to the nearest place to park
Ask for a price
No survey visit is needed: we price from pictures. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through.

FAQs for Knightsmill
What happens next?
You get a fixed quote and available dates. If we need another angle, we will ask.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
How long does resealing take?
Typically a couple of hours, then it needs to cure.
How quickly can you book me in?
That depends on our diary for your area. Send pictures with your postcode and we’ll reply with the earliest dates.
Do you cover Knightsmill?
Yes, we do. Repair technicians travel to Knightsmill from across the region, with no extra charge for travel.
Can you repair something that’s been repaired before?
Typically, yes. The old repair comes out first, so let us know about it.
How long before I can shower?
Normally about a day later. We confirm before we leave.
Honest limits
In fairness, some problems need a different fix:
- Gaps so wide they need filling or trims before sealing
- A bath or tray that moves, until its support is fixed
- Loose tiles, which need refixing first
Not sure? Send pictures and we’ll give you a straight answer before booking.
Surfaces we repair
- Basins & vanity units
- Baths
- Wet rooms
- Kitchen worktops & sinks
- Shower trays & enclosures
Looking after it afterwards
How the surface is treated afterwards matters. Here’s what we suggest:
- Dry the seal after bathing
- Do not stand toiletries on the seal
- Clean the joints with a mild cleaner
- Open a window after bathing
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.
