Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
New build mastic for homes and businesses in Mill Green
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. If you have cracks appearing as a new home settles and gaps between new skirting and floors, we can put it right, on show homes, windows & doors and plot handovers alike.
Around Mill Green, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, in Mill Green and everywhere else we cover.

Looking after it afterwards
To keep the joints looking good and working properly:
- Wait for the cure time before using a resealed shower
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Do not seal over failed sealant yourself
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Do you need new build mastic in Mill Green?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Any of these means the joints need attention:
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Thatcham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Mill Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
