New-build mastic & snagging in Headcorn, Kent
Our applicators work in Headcorn on 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.
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Cracked sealant around new window and door frames
Can I do it myself?
The difference is mostly in the preparation and the 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
New build mastic in Headcorn
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on kitchens, plot handovers and show homes, and common reasons people get in touch are new-build shower sealant that has already split and gaps behind new kitchen upstands.
In smaller places like Headcorn, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

Do you need new build mastic in Headcorn?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
It’s worth asking for a quote if you see:
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
For new homes near Headcorn station, it’s worth checking the sealant early, while snags are still fresh.

What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Plumbing faults behind the sealant
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
