Why it’s worth doing now in East Saltdean
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. In a smaller place like East Saltdean, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

About our new build mastic in East Saltdean
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. Common call-outs are for untidy sealant flagged on a snagging list and joints pulling apart as timber shrinks, across skirting & floors, plot handovers and show homes.
In and around East Saltdean, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
Your job is guaranteed for a year, as with all our work.

What else we do in East Saltdean
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Wait for the cure time before using a resealed shower
- Use the extractor fan every time you shower
- Keep photos and emails about snagging items
- Clean sealant with mild detergent, not abrasives
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In a smaller place like East Saltdean, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

What we’re called out for in East Saltdean
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Common reasons people contact us are:
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Gaps between new skirting and floors
For new homes near Southease station, it’s worth checking the sealant early, while snags are still fresh.

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
