How we handle new build mastic in Lindfield
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on show homes, bathrooms & en suites and skirting & floors, and common reasons people get in touch are gaps behind new kitchen upstands and plot mastic for developers ahead of handover.
If you’ve bought a new home in or near Lindfield, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Each job carries a 12-month guarantee, whatever its size.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with right away
- Look at the sealant regularly in the first couple of years
- Put sealant faults on your snagging list early
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Signs you need new build mastic in Lindfield
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
If you can see any of these, it’s time to have the joints looked at:
- Smeared, uneven beads picked up at snagging
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build
In and around Lindfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In an older home around Lindfield, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where 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.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours in a single home. A visit to Lindfield is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
