About our remedial sealant in Dinton
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Typical jobs include products that weren’t meant for the joint and a shower that leaks however often it’s resealed, on botched or over-sealed joints, expansion joints and shrunken worktop sealant.
In a village or hamlet like Dinton, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Each job carries a 12-month guarantee.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the cost of remedial sealant
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- Whether the work is at height
- How much there is to do
- The old material and how stubborn it is
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
What we need to know
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
- Where the property is
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Act on a lifting corner straight away
- Keep bleach and abrasives off the bead
- Find out why the sealant failed first
- Check trays and worktops don’t move
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, phone 0345 464 0079 or email us.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Bathrooms and kitchens in Dinton
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of Saints Peter and Paul, walls and floors in older homes can move, and sealant and grout show it first.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Dinton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

What the job involves on each surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We will tell you what we find.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
When to call us in Dinton
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Most people get in touch when they notice something like this:
- Over-sealed joints coming away
- Torn expansion joints
- Leaks that keep coming back after resealing
- Kitchen joints letting water behind the worktop
Letting a property close to Haddenham & Thame Parkway station? Then a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before you book
