Bath resealing at your home in Catherington
A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, in a neat, continuous bead. We regularly repair shower trays & enclosures, basins & vanity units and kitchen worktops & sinks, and the jobs we see most are sealant that’s split or lifting and stained silicone.
Every job is backed for twelve months. We return to put right any problem with the work.

How the visit works
Nothing needs to be moved out of the room beforehand. We bring everything we need with us, lay protective sheets and start once you are happy with the plan. It generally takes around two hours, and you are welcome to carry on with your day while we work.
- We cut out and remove all of the old sealant.
- The joint is cleaned and any mould treated.
- The joint is dried thoroughly.
- We fill a bath with water before sealing so the gap is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.
Before we arrive
- Ensure the room can be ventilated
- Avoid using the area for a few hours before we arrive
- Clear toiletries, mats and anything else from around the area

Looking after it afterwards
Simple care helps the repair last. Our advice:
- Use the extractor fan
- Clean the sealant gently and regularly
- Wipe the joints dry after use
- Keep bottles off the joints
Run the extractor fan, dry the joints after bathing, and give them a regular clean with a mild cleaner to slow mould growth.
Black mould in sealant is not just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.

What affects the price in Catherington
We do not charge extra for travel to Catherington. The price depends on:
- Access to the area
- Previous DIY repairs that have to come out
- How many items we do on one visit
- How much damage there is
What it costs depends on the type and amount of damage, the material and how many jobs we combine into one visit. You get a fixed quote from your photos, so there are no surprises on the day.
Getting a price from pictures
Almost every job we do is priced from pictures. This is what to send:
- Something in shot to show the size
- One sharp close-up of the damage
- A wider photo showing the entire bath or shower
- Where you are, by postcode
Pricing is simple: snap the damage close up and then the whole item, send them to us with your postcode, and we will reply with a fixed quote. Quotes are free and no obligation.
Landlords, agents and businesses in Catherington
We are used to working with agents and managing companies. Just send pictures, the address and how to get access and we’ll handle the rest.
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover. We’re CHAS, Constructionline and SafeContractor accredited.
DIY kit or professional repair?
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
What else we do in Catherington
Catherington questions
Can landlords book you?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
Will it make a mess?
We protect the room with dust sheets and masking first, and we clean up when we’ve finished.
Is a repair better than a new one?
In most cases, yes. A repair skips the removal, fitting and redecorating. We will be honest if it’s not worth it.
Why does mould come back so fast?
Mould needs moisture. Run the fan, dry the joints and the new seal stays cleaner for longer.
Which areas do you work in?
We cover the entire UK, including Catherington and the rest of Hampshire. Send your postcode with your photos and we’ll offer you dates.
Can you redo someone else’s repair?
In most cases. The old repair comes out first, so let us know about it.
When can I use the bath after resealing?
We will give you the curing time.
Why does the silicone keep cracking?
Something is moving. If it keeps happening, the support may need fixing.
When a repair isn’t the answer
In fairness, there are a few things a repair won’t fix:
- Movement in the bath or tray
- Gaps so wide they need filling or trims before sealing
- Rotten walls or floors behind the bath
If in doubt, send pictures and we will say what we think.
Materials we repair
- Wet rooms
- Shower trays & enclosures
- Kitchen worktops & sinks
- Basins & vanity units
