About our new build mastic in Maresfield
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on plot handovers, windows & doors and skirting & floors, and the jobs we see most are cracked sealant around new window and door frames and sealant that never bonded to the surface.
For a small place like Maresfield, the journey and access are planned in advance, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job.

Joints and finishes in Maresfield homes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Uckfield station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Don’t wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
- Wait for the cure time before using a resealed shower
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

What we’re called out for in Maresfield
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Look out for these signs:
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
In and around Maresfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How it works
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. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Maresfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
