What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a morning or an afternoon for most single baths and showers, depending on how much there is to do. Somewhere as small as Long Wittenham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Before we arrive
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Why it’s worth doing now in Long Wittenham
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. Lumpy sealant with smears on the tiles has the opposite effect. Around Long Wittenham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why choose Mr Mastic in Long Wittenham
- Neat joints and a tidy finish
- Domestic, commercial and hotel work
- Anti-fungal sanitary silicone in wet areas
- Trusted Arbo and Everbuild sealants
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep an eye on the corners, where splits start
- Wipe up water along the back of the worktop
- Let new sealant cure fully before it gets wet
- Never pick at the silicone with a blade
Check the sealant now and then. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just call 0345 464 0079 or send us an email.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.
Do you need bathroom resealing in Long Wittenham?
Older sealant shrinks and hardens. In kitchens it often shrinks away from the back edge, leaving a thin gap where water and food collect. Heat from the hob and strong sprays speed it along.
Signs it’s time to call us include:
- Gaps between the worktop and the wall
- Failed sealant on the screen profile
- Water getting behind the bath panel
- Cracked, shrunken or lifting silicone
Schools such as Long Wittenham (Church of England) Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Different surfaces, different methods
Wet rooms
Wet rooms rely on sound joints at floor and wall junctions. They get anti-fungal sanitary silicone, and our work is on the visible joints only.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. The extra cleaning is what makes the bead last.
Honest limits
A few problems are outside what sealant work can do:
- Damage behind the tiles that needs a tiler
- A tray that rocks until it’s re-bedded
- Cracks in the tray itself rather than the joint
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Common questions in Long Wittenham
Do you work for landlords with property near Appleford station?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Long Wittenham within the area you cover?
Yes, Long Wittenham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you do kitchens as well as bathrooms?
Yes. The old sealant is cut out and the joint degreased, because cooking grease stops silicone sticking, then we reseal in a colour to suit.
My sealant has gone black. Can you sort it?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How long does a bath or shower reseal take?
It depends on how many joints there are and how much old sealant has to come out. For most single baths or showers, allow a couple of hours.
Is it OK to put new sealant on top of the old bead?
No. Fresh silicone can’t stick to the old bead, so it peels away and hides mould and water. We always take the old sealant out completely.
