New build mastic in Harmans Water, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have beads laid onto grit and dust from the build and sealant work across a run of new homes, we can put it right.
Where new homes go up in smaller places like Harmans Water, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

New build mastic around Harmans Water
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Harmans Water is part of Bracknell, one of the post-war new towns. Bracknell has kept growing, with newer neighbourhoods added to the original town. Older homes need their sealant and floor joints renewing, newer ones checking at snagging.
For new homes near Martins Heron station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Use the extractor fan every time you shower
- Do not wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
- Follow the cure time we give you
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. A visit to Harmans Water is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

What the job involves on each surface
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Movement caused by a poorly fitted tray or bath
- Broken tiles or a split tray
- Plumbing faults behind the sealant
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Why act early in Harmans Water
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. Homes in smaller places like Harmans Water 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.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
