About our remedial sealant in Harcourt Hill
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you are dealing with kitchen joints letting water behind the worktop and thick, messy sealant smeared over tiles, we can help.
For a small place like Harcourt Hill, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Our work is backed for twelve months.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Harcourt Hill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition
So the new joints stay in good condition:
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Run the fan after every shower
- Ask why a joint failed before redoing it
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
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.
What remedial sealant looks like in Harcourt Hill
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Harcourt Hill has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to Church of St Lawrence include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Matthew Arnold School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Oxford station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

What affects the quote in Harcourt Hill
There’s no set price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Which sealant suits the joint
- Working hours on commercial sites
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote

- Roughly how big the job is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.
How the job changes by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Harcourt Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
