What we’re called out for in Shacklewell
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.
The problems people generally mention when they call are:
- A second bead peeling off the first
- A shower that leaks however often it’s resealed
- Products that weren’t meant for the joint
- Floor or wall movement joints that have failed
Homes close to Church of St Barnabas include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Remedial sealant in Shacklewell
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you call 0345 464 0079 or email us, and say how long ago it was last done. Typical jobs include gaps opening along the back of the worktop and sealant that came away because the surface wasn’t prepared, across leaking tray & enclosure joints, expansion joints and mouldy bath & shower sealant.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Each job carries a 12-month guarantee, whatever its size.

Landlord and commercial work in Shacklewell
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Shacklewell, the repair is bigger than a sealant job.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Shacklewell. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a soft cloth, not a scourer, on silicone
- Air the bathroom so the sealant can dry
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
