Work for landlords and builders
Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which matters when someone is living in the home.
We work for landlords, letting agents and housing providers in Cowley as well as homeowners. A repair between tenants keeps the property empty for less time, and it usually costs far less than a refit.
Bath resealing at your home in Cowley
We cut out all of the old sealant, treat any mould, and apply fresh mould-resistant silicone. We reseal baths, showers, sinks and worktops, including the awkward bits behind the taps. If you are dealing with sealant that’s split or lifting and black mould in the sealant, we can normally put it right.
Every repair comes with our one-year guarantee.

Common problems we fix in Cowley
Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all wear it down.
These are the problems we are asked about most:
- Water getting behind the bath or tray
- Gaps by the taps
- Old sealant that looks dirty
- Silicone coming away from the tiles
Before you book anyone
- How your room will be protected
- When it can be used again
- Whether the price is fixed and includes VAT
- Aftercare advice
Honest limits
A repair isn’t always the answer, and we would rather say so up front. Repairs will not solve:
- Gaps so wide they need filling or trims before sealing
- Water damage behind the bath that needs a builder
- Movement in the bath or tray

Aftercare tips
Most damage we see is avoidable. These habits help:
- Keep bottles off the joints
- Open a window after bathing
- Dry the seal after bathing
- Ventilate the bathroom well
Do not scrape the sealant with anything sharp, and don’t stand bottles on the seal.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
Why it’s worth resealing in Cowley
Resealing costs very little, and it protects everything around the bath. Failed sealant can lead to water damage that is much more expensive. The price depends on how much damage there is and what kind, the material and how many jobs we combine into one visit. You get a fixed price from your pictures, so you know the cost before booking.

Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, for the same reason.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
Can I fix it myself?
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Getting it right first time is typically cheaper.
For a hairline mark somewhere you’ll never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
Cowley questions
Is it messy?
Dust sheets and masking go down before we start, and we clean up when we’ve finished.
Can you do more than one item on the same visit?
Of course, and it generally saves money. Just add the extra items to your pictures and you will get one combined price.
My seal keeps tearing. Why?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
What does bath resealing cost?
The exact price depends on the damage, so we quote from pictures. You will get a fixed figure before you book.
