Remedial sealant & repairs in Woodstock, Oxfordshire
Removing failed, mouldy or leaking sealant and putting it right for householders, landlords and businesses in Woodstock. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- Mould trapped under a layer of silicone
Why deal with it now?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. If they’re not, we will tell you. In an older home around Woodstock, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- We leave the area clean and tidy
- Colour picked to suit the job
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal sanitary silicone in wet areas
How we handle remedial sealant in Woodstock
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. Common call-outs are for beads that never stuck properly and gaps opening along the back of the worktop, across expansion joints, botched or over-sealed joints and shrunken worktop sealant.
In a smaller place like Woodstock, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
All of our work is guaranteed for twelve months.

How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Woodstock, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Where is Mr Mastic based?

How long will it take to strip and reseal the joint?
Allow a few hours for most joints, depending on how much old sealant has to come out. You’ll know the timing when we quote.
What happens if the problem is the tray or the plumbing?
Then we explain what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Act on a lifting corner straight away
- Air the bathroom so the sealant can dry
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- A bath, tray or worktop that moves until it’s properly fixed
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Bathrooms and kitchens in Woodstock
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Woodstock. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as Woodstock Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Hanborough station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Signs you need remedial sealant in Woodstock
Movement tears sealant that isn’t designed for it. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.
Most people get in touch after spotting one of these:
- Kitchen joints letting water behind the worktop
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
- Dark patches showing through the sealant
Homes close to Church of St Mary Magdalene include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before you book
- Are they insured?
- How the joint is cleaned and prepared
- When the joint can take water or movement
- Is VAT in the price?
How the job changes by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
