Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved

- Which sealant suits the joint
- Access and height
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.
What we need to know

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy.

We bring what the job needs, so it can be finished in one trip where possible.

How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Can you fix a reseal that hasn’t worked?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.

No. We work neatly, protect the area around the joints and tidy up afterwards.
Remedial sealant in Thorney: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For landlords with property near Iver station, a joint that keeps failing is best fixed properly while the property is empty. Schools such as St Catherine Catholic Primary School are buildings too, and 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. For an older house near a landmark such as St. Leonard's, older homes can move a little, which is hard on rigid grout and tired sealant.

Aftercare tips
So the new joints stay in good condition:
- Act on a lifting corner right away
- Run the fan after every shower
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Why it’s worth doing now in Thorney
Ripping out a bathroom isn’t normally needed. If the bath, tray and tiles are sound, remedial resealing usually puts it right. If they’re not, we will tell you. Older cottages and farmhouses around Thorney can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
