New build mastic for homes and businesses in Devil's Den
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for frame joints opening as the plaster dries and shower seals failing in the first year or two, across windows & doors, kitchens and skirting & floors.
Work in a small place like Devil's Den just needs the journey and access planning, and the work itself is the same as on any site.
Our work is backed for twelve months.

Surface by surface
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We will plan around viewing times.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours in a single home. Somewhere like Devil's Den needs a little journey planning: 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 going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

Signs you need new build mastic in Devil's Den
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
People usually contact us after spotting one of these:
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
For new homes near Staplehurst station, it’s worth checking the sealant early, while snags are still fresh.

Leave it or put it right?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Devil's Den can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we can reseal it properly.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
