Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Avoid scourers and strong chemicals on sealant
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic in Winchester
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. If you’re dealing with new-build shower sealant that has already split and cracks appearing as a new home settles, we can put it right, on bathrooms & en suites, kitchens and plot handovers alike.
Winchester is big enough to have new developments going up alongside its older streets. New homes need their plot mastic and sealant finished well, and owners often find snags in the first year or two, as a new house dries out and settles.
Each job carries a 12-month guarantee, whatever its size.
The process
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For homes and businesses in busier parts of Winchester, parking needs a little planning. For flats, mention stairs, lifts and shared entrances as well.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Mention if the joints have been sealed before

What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. In flats, shops and offices in Winchester, a failed joint can let water into the unit below or behind a wall, where it’s often found late and is bigger to put right.
