How we handle new build mastic in Horsebridge
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on windows & doors, skirting & floors and bathrooms & en suites, and people most often call us about sealant applied over dusty or wet surfaces and new-build shower sealant that has already split.
Somewhere as small as Horsebridge, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Keeping the joints in good condition
Looking after new joints is easy:
- Follow the cure time we give you
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Clean sealant with mild detergent, not abrasives
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
Do you need new build mastic in Horsebridge?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Sealant applied over dusty or wet surfaces
- Gaps between new skirting and floors
If you’ve bought a new home near Mottisfont & Dunbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How the job changes by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing.

New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
