Remedial sealant in Oakley
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. Typical jobs include black mould underneath the bead and over-sealed joints coming away, across expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.
In and around Oakley, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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, then guaranteed for a year.
Surface by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.

Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Oakley and the rest of Hampshire.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Can you remove sealant that’s been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
What affects the quote in Oakley
There’s no set price list, because jobs vary so much. What we look at:
- The amount of work
- Working hours on commercial sites
- The type of sealant required
- How easy the joints are to reach
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- The rough size of the job
- The problem you’ve noticed
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Common problems we fix in Oakley
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 sets the depth and stops that.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
For an older house near a landmark such as St John's, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- Whether the sealant suits the joint
- How the colour is chosen
- What the cure time is
- What preparation is included

What else we do in Oakley
Landlord and commercial work in Oakley
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
For anyone letting property in or around Oakley, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
- Get the cause of a repeat leak found before resealing
- Keep an eye on the ceiling below the bathroom
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. For a job in Oakley, 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
