Remedial sealant for homes and businesses in Hardwick
Movement and expansion joints fail when the sealant can’t 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 over-sealed joints coming away and decorators’ caulk around a bath or shower, across expansion joints, leaking tray & enclosure joints and botched or over-sealed joints.
Somewhere as small as Hardwick, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. 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, you get the same one-year guarantee.

FAQs for Hardwick
Do you cover smaller places like Hardwick?
Yes, Hardwick is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What guarantee comes with remedial sealant in Hardwick?
All our work, in Hardwick and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Which products 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’ll tell you what we are using.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Hardwick.
What does remedial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Do you work for letting agents?
Yes, regularly. Several properties can go on one quote.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
What affects the quote in Hardwick
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- The number of rooms or windows
- Working hours on commercial sites
- The amount of work
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Whether it has been sealed before
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Remedial sealant in Hardwick: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Other services in Hardwick
Do you need remedial sealant in Hardwick?
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
These are the problems we’re asked about most:
- A second bead peeling off the first
- Caulk or the wrong sealant used in a wet area
- Repeat leaks from the same joint
- Floor or wall movement joints that have failed
In and around Hardwick, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- How long the guarantee is
- Whether you can choose the colour
Surface by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, so the sealant grips the two sides only.
