About our new build mastic in Lower Dicker
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant generally lacks. If you are dealing with second-fix sealing on new plots and messy sealant that spoils new finishes, we can help, on windows & doors, show homes and bathrooms & en suites alike.
Work in a small place like Lower Dicker just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

When to call us in Lower Dicker
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Most people get in touch after spotting one of these:
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Berwick (Sussex) station, the sealant around baths, showers and frames is worth checking in the first year or two.

Lower Dicker questions
Can you do new build mastic in Lower Dicker?
Yes. Our work covers London and the South East, and Lower Dicker is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Berwick (Sussex) station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours in a single home. We will give you a better idea when we quote.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Can you work from my snagging list?
Yes. Send the list and a few pictures of the sealant items, and we’ll quote. We’ll flag anything that needs another trade.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clean sealant with mild detergent, not abrasives
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with straight away
- Keep pictures and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. In a small place like Lower Dicker, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Somewhere as small as Lower Dicker, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
