New-build mastic & snagging in Headley, West Berkshire
Our applicators work in Headley on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
- Internal frame sealant that has split
How we handle new build mastic in Headley
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on plot handovers, skirting & floors and kitchens, and common reasons people get in touch are cracks appearing as a new home settles and sealant that never bonded to the surface.
For a small place like Headley, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Big or small, you get the same one-year guarantee.

For landlords and businesses
Landlords and agents in Headley can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Aftercare tips
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Raise failed sealant with the developer while you’re covered
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
What sealant work cannot fix
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Common problems we fix in Headley
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Common reasons people contact us include:
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
In and around Headley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
