Normally about a day later. We will tell you the exact time.
Can tenants book a repair?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.

- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- We dry the joint thoroughly.
- For a bath, we fill it with water first so the joint is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, taps included.

- Keep a parking space free if you can
- Ensure the area is dry

Aftercare tips
It’s all simple stuff:
- Dry the seal after bathing
- Open a window after bathing
- Store bottles on a shelf
- Reseal when black spots will not clean off
Do not scrape the sealant with anything sharp, and keep shampoo bottles off the joints.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
DIY repairs versus a professional job
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. Just mention it when you send pictures, as it can add time.
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
Is resealing worth it?
Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. We don’t add extras on the day. What we quote from your pictures is what you pay, unless the damage turns out to be different, in which case we talk to you first.
Why book with us
- Same prices wherever you are
- A year’s guarantee on all work
- No need to remove anything
- Most jobs done in one visit

Landlords, agents and businesses in Knowle
Builders use us to fix snagging damage before handover, saving last-minute replacements. We can visit several plots in one trip to keep costs down.
Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
