About our new build mastic in Little Posbrook
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We’re often asked to deal with sealant applied over dusty or wet surfaces and cracks appearing as a new home settles, on plot handovers, skirting & floors and windows & doors.
Somewhere as small as Little Posbrook, 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

How it works
The work is kept neat and contained to the joints we are treating. The job generally takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. Somewhere like Little Posbrook needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Joints and finishes in Little Posbrook homes
Little Posbrook is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Follow the cure time we give you
- Keep pictures and emails about snagging items
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through cannot. If you are unsure which you have, call 0345 464 0079 or drop us an email with pictures. Older cottages and farmhouses around Little Posbrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

What we are called out for in Little Posbrook
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 first.
Keep an eye out for any of the following:
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
If you’ve bought a new home near Fareham station, the sealant around baths, showers and frames is worth checking in the first year or two.
