About our new build mastic in Coneyhurst
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for second-fix sealing on new plots and joints pulling apart as timber shrinks, on kitchens, show homes and plot handovers.
For a small place like Coneyhurst, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

How the visit works
At the end, we look at the finished work together. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. In a small place like Coneyhurst, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Clear items away from the joints we are working on
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Looking after it afterwards
Looking after new joints is easy:
- Watch for new gaps as the house dries out
- Use the extractor fan every time you shower
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.

- The type of sealant required

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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. All the old material has to come out first.
