New-build mastic & snagging in Lenham Heath, Kent
Our applicators work in Lenham Heath on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.

- Frame joints opening as the plaster dries
New build mastic in Lenham Heath
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you’re dealing with shower seals failing in the first year or two and cracked caulk along new skirting, we can put it right, on show homes, skirting & floors and plot handovers alike.
In a village or hamlet like Lenham Heath, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Advice
Lenham Heath: your questions answered
I let a flat near Lenham station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Lenham Heath within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you use white or clear sealant?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room before we begin.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first.
When something else is needed
In fairness, some problems need a different trade:
- Leaking fittings rather than failed sealant
- A tray or bath that isn’t properly supported, until it’s fixed
- Structural cracks in walls or ceilings
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, 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.
Looking after it afterwards
To keep the joints looking good and working properly:
- Follow the cure time we give you
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
When to call us in Lenham Heath
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
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.

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Lenham Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
