How we handle new build mastic in Leybourne
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. If you have cracks appearing as a new home settles and sealant applied over dusty or wet surfaces, we can put it right, on bathrooms & en suites, windows & doors and skirting & floors alike.
Work in a small place like Leybourne just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Around Leybourne, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
