What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Thruxton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic for homes and businesses in Thruxton
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. Common call-outs are for leaking shower tray seals in a new home and internal frame sealant that has split, across windows & doors, plot handovers and skirting & floors.
For a small place like Thruxton, the journey and access are planned in advance, and the work itself is the same as on any site.

What affects the cost of new build mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- How many areas need sealing
- The old material and how stubborn it is
- How easy the joints are to reach
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Thruxton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Different surfaces, different methods
Show homes

Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Signs you need new build mastic in Thruxton
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Keep an eye out for any of the following:
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
