Surface by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Remedial sealant for homes and businesses in Upper Harbledown
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we will tell you rather than reseal something that won’t fix it. If you’re dealing with decorators’ caulk around a bath or shower and dark patches showing through the sealant, we can put it right, on failed movement joints, expansion joints and mouldy bath & shower sealant alike.
Around Upper Harbledown, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Upper Harbledown, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- 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.
Getting ready for the visit

Why it’s worth doing now in Upper Harbledown
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Upper Harbledown can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Do you work for landlords with property near Canterbury West station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do remedial sealant in Upper Harbledown?

Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How long will it take to strip and reseal the joint?
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.
What happens if the problem is the tray or the plumbing?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
DIY versus a professional finish
What a professional job adds is preparation and the right 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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Tiles that have come away from the wall
- A tray or worktop that needs refixing first
- Sealant in an older building that needs testing for asbestos first
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Report a tray that rocks or a worktop that lifts
- Check ceilings under showers for marks
- Use a soft cloth, not a scourer, on silicone
- Air the bathroom so the sealant can dry
Keep the room ventilated: run the fan during and after showers, or open a window.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Bathrooms and kitchens in Upper Harbledown
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as St Edmund's School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Homes close to Church of St. Gabriel include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Canterbury West station, a joint that keeps failing is best fixed properly while the property is empty.
