About our new build mastic in Kingsclere
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on bathrooms & en suites, show homes and kitchens, and the jobs we see most are smeared, uneven beads picked up at snagging and skirting joints opening in the first winter.
Where new homes go up in smaller places like Kingsclere, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours in a single home. Parking around Kingsclere is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
How to look after the new joints
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Keep pictures and emails about snagging items
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Signs you need new build mastic in Kingsclere
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Keep an eye out for any of the following:
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
If you’ve bought a new home near Thatcham station, the sealant around baths, showers and frames is worth checking in the first year or two.
