About our bath resealing in Four Lanes
A reseal is a small job that makes a big difference. Fresh joints make the whole room look cleaner, and they keep water out. If you’re dealing with black mould in the sealant and gaps by the taps, we can normally put it right, on shower trays & enclosures, kitchen worktops & sinks and wet rooms alike.
All of our repairs are guaranteed for twelve months in Four Lanes and everywhere else. If something goes wrong with the work, we come back.

Your questions about bath resealing in Four Lanes
What areas do you cover?
Across the UK, and that includes Four Lanes. Our prices are the same everywhere.
Is a repair better than a new one?
Usually, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.
Are you accredited?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
How long before I can shower?
Normally about a day later. We’ll tell you the exact time.
How do I get a price for bath resealing in Four Lanes?
Every job gets a fixed quote based on photos of the damage. Send a close-up of the damage and a wider photo with your TR16 postcode.
Is my repair covered?
All our work carries our one-year guarantee. We will explain what it covers when we quote.
Do you seal over the old sealant?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Can tenants book a repair?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
How the visit works
On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take a couple of hours. We clean up when we’re done and tell you when it’s ready to use.
- First we strip out every bit of the old mastic.
- We clean the joint and treat any mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- New mould-resistant silicone goes on and is tooled to a neat finish, taps included.
How to prepare
- Let us know which floor the room is on
- Mention any earlier repairs or resurfacing
- Keep pets and children out of the room while we work
Getting a price

Can I fix it myself?
We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is generally the cheaper route.
What we are called out for in Four Lanes
In time, even good sealant discolours particularly in a well-used bathroom. Steam, soap and movement all wear it down.
The things clients normally mention when they call are:
- Discoloured, yellow sealant
- An untidy old seal
- Black spots in the silicone
- Gaps in the seal
Questions to ask before booking
- When it can be used again
- What preparation is included
- Aftercare advice
- Whether the colour is mixed to match
Landlords, agents and businesses in Four Lanes

Hotels, guest houses and holiday lets can’t afford rooms out of action for long, so we keep visits short and tidy. We will fit around changeovers where we can.
Honest limits
Some jobs are not right for a repair, including:
- A flexing bath

- Tiles that move, until they’re refixed
If in doubt, send photos and we’ll say what we think before you book.

- Kitchen worktops & sinks
- Wet rooms
- Shower trays & enclosures
- Baths

Aftercare tips
Looking after the surface is easy:
- Use the extractor fan
- Clean the joints with a mild cleaner
- Air the room after use
- Dry the seal after bathing
Keep the room well ventilated, and dry the joints after bathing to keep mould away.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Prices and what affects them
We give every job a fixed price from photos. These are the things that affect it:
- Any earlier repairs that need removing first
- The material and finish
- How easy the damage is to reach
- The size and number of damaged areas
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 doing several things on one visit costs less than separate visits.
How to get a fixed price
Most quotes are done from pictures alone. To make it quick:
- The material, if you know it
- A coin beside the damage so we can judge size
- The postcode, so we can plan the visit
- A wider photo showing the whole bath or shower
Call 0345 017 0787 or use the quote form. With a clear picture of the damage and one of the whole bath or shower, we can give you a fixed price.
Why reseal now?
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.
