About our new build mastic in Broadstone
We work in new homes and on new-build sites across Broadstone. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you have gaps behind new kitchen upstands and shower seals failing in the first year or two, we can put it right, on bathrooms & en suites, plot handovers and kitchens alike.
Somewhere as small as Broadstone, 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.
Our work is backed for twelve months.

What the job involves on each surface
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.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Your questions about new build mastic in Broadstone
Do you cover Broadstone for new build mastic?
Yes, Broadstone is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Broadstone?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Kent.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Movement caused by a poorly fitted tray or bath
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours in a single home, and the area is left clean. For a village or hamlet like Broadstone, 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 start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

When to call us in Broadstone
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Signs it’s time to call us include:
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Lenham station, the sealant around baths, showers and frames is worth checking in the first year or two.

- How long to leave it before use
