About our new build mastic in Cowesfield Gate
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you’re dealing with cracked sealant around new window and door frames and gaps between new skirting and floors, we can put it right, on bathrooms & en suites, kitchens and plot handovers alike.
Work in a small place like Cowesfield Gate just needs the journey and access planning, and the work itself is the same as on any site.
All of our work is guaranteed for twelve months.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Aftercare tips
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

Why it’s worth doing now in Cowesfield Gate
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Cowesfield Gate, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
