Our Prep and Protection Process

Great finishes start with proper prep. Before painting, we:

Protect floors, furniture, and non-painted surfaces
Remove dust, light debris, and surface contaminants
Patch nail holes, minor cracks, and small imperfections
Sand as needed for a smooth, uniform profile
Caulk trim gaps where appropriate
Prime repaired or stained areas before topcoats

This process helps improve adhesion, finish consistency, and long-term performance.

Together, we will bring your vision to life.
