New build mastic for homes and businesses in Brightwell Baldwin
We work in new homes and on new-build sites across Brightwell Baldwin. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We are often asked to deal with new-build shower sealant that has already split and cracks appearing as a new home settles, on kitchens, bathrooms & en suites and show homes.
In a village or hamlet like Brightwell Baldwin, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job.

When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
- Broken tiles or a split tray
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered to the agreed spec.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How to look after the new joints
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a village or hamlet like Brightwell Baldwin, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Why it’s worth doing now in Brightwell Baldwin
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Brightwell Baldwin can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
