Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
New build mastic in West Twyford, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on show homes, plot handovers and skirting & floors, and common reasons people get in touch are frame joints opening as the plaster dries and smeared, uneven beads picked up at snagging.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
All our work comes with a 12-month guarantee.

Do you need new build mastic in West Twyford?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Common reasons people contact us are:
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
- Second-fix sealing on new plots
For new homes near Stonebridge Park station, it’s worth checking the sealant early, while snags are still fresh.

Advice
Different surfaces, different methods
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
