New-build mastic & snagging in Marlow Common, Buckinghamshire
We cover Marlow Common for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

Common problems we fix in Marlow Common
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People generally contact us when they notice something like this:
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
For new homes near Marlow station, it’s worth checking the sealant early, while snags are still fresh.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Marlow Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
