How we handle new build mastic in Codmore Hill
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. Typical jobs include cracked sealant around new window and door frames and messy sealant that spoils new finishes, on show homes, windows & doors and plot handovers.
Somewhere as small as Codmore Hill, 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.
We stand behind the work with a one-year guarantee.

Why act early in Codmore Hill
A quick bead over the top of the old sealant can look fine at first, 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. Older cottages and farmhouses around Codmore Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Different surfaces, different methods
Skirting and floors

Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

What we’re called out for in Codmore Hill
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Any of these means the joints need attention:
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
For new homes near Pulborough station, it’s worth checking the sealant early, while snags are still fresh.
