About our remedial sealant in Shipton-on-Cherwell
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. If you’re dealing with dark patches showing through the sealant and sealant that came away because the surface wasn’t prepared, we can help, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant alike.
Around Shipton-on-Cherwell, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. Somewhere like Shipton-on-Cherwell needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- 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
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

How the job changes by surface
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. Where a wall is exposed, as many are in small places like Shipton-on-Cherwell, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
What you get with us
- A choice of colours where the product allows
- 12-month guarantee on every job
- Approved under the ARBOMaster scheme
- Fully insured

What remedial sealant looks like in Shipton-on-Cherwell
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For landlords with property near Tackley station, botched sealant from a previous quick fix is easier to strip out between tenants. Homes close to Church of Holy Cross include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Shipton-on-Cherwell questions
Can you do remedial sealant in Shipton-on-Cherwell?
Yes, Shipton-on-Cherwell is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Is Shipton-on-Cherwell within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, usually. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

What affects the cost of remedial sealant
You’ll get a clear quote before any work starts. It’s based on:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Mould in or behind the old joints
- The amount of work
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 the work is at height. Your quote takes all of that into account.
What to tell us for a quote
When you call or email, these details help:
- Pictures of the joints, sent by email
- Where the property is
- What’s wrong with the joints now
- Any previous sealing or DIY work
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Plumbing leaks behind walls or under trays
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

Signs you need remedial sealant in Shipton-on-Cherwell
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Any of these means the joints need attention:
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
- Worktop sealant that has shrunk and split
Managing a site like The Marlborough Church of England School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
