Remedial sealant for homes and businesses in Folkestone
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on shrunken worktop sealant, expansion joints and failed movement joints, and the jobs we see most are dark patches showing through the sealant and a second bead peeling off the first.
Homes around Folkestone have been extended and refitted over the decades. A common problem is new sealant laid over old, which never bonds properly, so we take every joint back to clean before anything new goes in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- Working hours on commercial sites
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- Where the property is
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Remedial sealant around Folkestone
Folkestone is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Folkestone Central station, a joint that keeps failing is best fixed properly while the property is empty. Schools such as Stella Maris Catholic Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In a family home in Folkestone, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. Parking in a town like Folkestone is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Other services in Folkestone
What we are called out for in Folkestone
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Keep an eye out for these signs:
- A second bead peeling off the first
- Movement joints that have split or pulled away
- Dark patches showing through the sealant
- Sealant peeling off a dusty or damp surface
If you live in an older home near United Reformed Church, walls and floors in older homes can move, and sealant and grout show it first.
What your quote should include
- Which colour the sealant will be
- What preparation is included
- The length of the guarantee
- What product goes in the joint
How the job changes by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, which we will point out.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
