New build mastic for homes and businesses in Winnersh
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have skirting joints opening in the first winter and shower seals failing in the first year or two, we can help.
For a new home in or near Winnersh, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

New build mastic in Winnersh: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. A visit to Winnersh is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.

Advice
Why act early in Winnersh
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. Around Winnersh, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Signs you need new build mastic in Winnersh
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Keep an eye out for any of the following:
- Internal frame sealant that has split
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
In and around Winnersh, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How much experience the applicator has
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
- Whether they’re fully insured
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.
