How we handle new build mastic in Saunderton
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. If you have smeared, uneven beads picked up at snagging and second-fix sealing on new plots, we can help.
Older homes in small places like Saunderton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, you get the same one-year guarantee.

How the job changes by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.

Why it’s worth doing now in Saunderton
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Saunderton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
Watch the joints as the house settles. Small gaps can appear as the house dries.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

Do you need new build mastic in Saunderton?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
Look out for these signs:
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
For new homes near Saunderton station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
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 fails, we can still redo it.
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, then guaranteed for a year.
