New build mastic for homes and businesses in Radclive
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We’re often asked to deal with sealant work across a run of new homes and leaking shower tray seals in a new home, across skirting & floors, kitchens and show homes.
Older homes in small places like Radclive often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How it works
The work is kept neat and contained to the joints we are treating. The job usually takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. In a small place like Radclive, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Surface by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors.
When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Radclive, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
