Remedial sealant for homes and businesses in Cuddesdon
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. If you have beads that never stuck properly and worktop sealant that has shrunk and split, we can help.
Somewhere as small as Cuddesdon, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
All our work comes with a 12-month guarantee.

Common problems we fix in Cuddesdon
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Signs it’s time to call us include:
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
- Worktop sealant that has shrunk and split
- Floor or wall movement joints that have failed
If you look after a building such as Garsington Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- Whether the sealant suits the joint
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant

Cuddesdon: your questions answered
What guarantee comes with remedial sealant in Cuddesdon?
All our work, in Cuddesdon and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Cuddesdon?
Yes. Cuddesdon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Oxfordshire.
Can failed expansion joints be resealed?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
How long will it take to strip and reseal the joint?
The number of joints and layers decides it. We will tell you before we start.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Report a tray that rocks or a worktop that lifts
- Keep an eye on the ceiling below the bathroom
- Run the fan after every shower
- Act on a lifting corner straight away
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or email us.
Do not keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
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.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed colour-matched to the worktop.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the amount of work. Somewhere like Cuddesdon needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
How to prepare
- Mention any tricky access
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work

Remedial sealant in Cuddesdon: local notes

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
