New build mastic in Nettlestead Green, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have worktop and upstand sealant coming away and gaps between new skirting and floors, we can put it right.
Somewhere as small as Nettlestead Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You get a 12-month guarantee, the same in Nettlestead Green as everywhere else we work.

Nettlestead Green: your questions answered
Do you cover Nettlestead Green for new build mastic?
Yes, Nettlestead Green is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.

When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What sealant 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.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere as small as Nettlestead Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit

Advice
What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

- Sealant work across a run of new homes
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
For new homes near Yalding station, it’s worth checking the sealant early, while snags are still fresh.
