How we handle new build mastic in Cowey Green
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. We work on skirting & floors, bathrooms & en suites and show homes, and the jobs we see most are shower seals failing in the first year or two and messy sealant that spoils new finishes.
Somewhere as small as Cowey Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Cowey Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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
- Keep children and pets away from the work area
- Tell us about any water getting in
- Clear the area around the work

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid running a DIY bead over the old one
- Use the extractor fan every time you shower
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
Don’t 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.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Common problems we fix in Cowey Green
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Common reasons people contact us include:
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
If you’ve bought a new home near Great Bentley station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
