When to call us in Finstock
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
Common reasons people contact us are:
- Mould trapped under a layer of silicone
- A second bead peeling off the first
- Wide, uneven beads that look worse than the old ones
- A shower that leaks however often it’s resealed
For landlords with property near Finstock station, a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include
- Whether the sealant suits the joint
- When the joint can take water or movement
- How long the guarantee is
- How hidden problems are handled
Remedial sealant for homes and businesses in Finstock
In Finstock, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on mouldy bath & shower sealant, botched or over-sealed joints and expansion joints, and common reasons people get in touch are decorators’ caulk around a bath or shower and kitchen joints letting water behind the worktop.
In a village or hamlet like Finstock, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Whatever the size of the job, it’s backed by our 12-month guarantee in Finstock and across Oxfordshire.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Finstock, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

What the job involves on each surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. We will reseal and tell you if extraction looks to be the issue.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Remedial sealant around Finstock
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of the Holy Trinity, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Finstock Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Finstock: your questions answered
Can you help a landlord with a rental near Finstock station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Will you come out to Finstock?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you guarantee remedial jobs?
Yes, with our 12-month guarantee. Where we have flagged another fault, it needs fixing for the joint to last.
How long does remedial resealing take?
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.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Honest limits
In fairness, there are a few things sealant will not fix:
- Cracks in the fitting rather than the joint
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Landlord and commercial work in Finstock
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
Leave it or put it right?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Older cottages and farmhouses around Finstock can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
