Do you need new build mastic in Sandwich Bay Estate?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Keep an eye out for these signs:
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
New homes and floors in Sandwich Bay Estate
Sandwich Bay Estate 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved and we’ll quote.

Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
