What happens if it’s left?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Where a wall is exposed, as many are in small places like Kemprow, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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 happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Kemprow needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What we are called out for in Kemprow
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Common reasons people contact us are:
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- Wide, uneven beads that look worse than the old ones
- Mould trapped under a layer of silicone
For landlords with property near Radlett station, a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before you book
- How the colour is chosen
- How much experience the applicator has
- How the joint is cleaned and prepared
- Is VAT in the price?

Homes close to St John include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Schools such as Fair Field Junior School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
