Advice
About our new build mastic in Wadesmill
Across Wadesmill, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Typical jobs include smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, on show homes, bathrooms & en suites and plot handovers.
Older homes in small places like Wadesmill often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan after bathing
- Keep photos and emails about snagging items
- Avoid running a DIY bead over the old one
- Watch for new gaps as the house dries out
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
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.
