New build mastic for homes and businesses in Jericho
We work in new homes and on new-build sites across Jericho. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on windows & doors, skirting & floors and kitchens, and common reasons people get in touch are gaps behind new kitchen upstands and cracked sealant around new window and door frames.
For a new home in or near Jericho, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber

What we’re called out for in Jericho
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The problems people normally mention when they call include:
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Oxford station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Homes in smaller places like Jericho can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

How the job changes by surface
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Raise failed sealant with the developer while you are covered
- Check bath and shower seals every few months as the house settles
- Do not wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a job in Jericho, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
