Advice
How we handle new build mastic in Sharnal Street
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We work on kitchens, plot handovers and windows & doors, and common reasons people get in touch are skirting joints opening in the first winter and joints pulling apart as timber shrinks.
In a village or hamlet like Sharnal Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, in Sharnal Street and everywhere else we cover.

Honest limits
To be straight with you, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant

Joints and finishes in Sharnal Street homes
Sharnal Street is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Gillingham (Kent) station, it’s worth checking the sealant early, while snags are still fresh.

Questions from Sharnal Street
Can you do new build mastic in Sharnal Street?

Who should fix failed sealant in a new build?
Your builder, if you’re still in their snagging or warranty period. If that does not work out, we’re happy to quote and our work is guaranteed for a year.
What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
How long does new build mastic take?
Typically it takes a few hours in a single home. Bigger jobs take longer, and we’ll say how long yours will take.

Aftercare tips
A little care helps the new joints last. Our advice:
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
- Get a leaking seal dealt with right away
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
What we’re called out for in Sharnal Street
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The problems people normally mention when they call include:
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
Around Sharnal Street, as everywhere, new build mastic is only as good as the preparation behind it.
