1. Drywall Delivery & Material Staging →
Drywall sheets (often over 100 lbs each) are delivered and strategically stocked throughout the space to reduce handling, prevent damage, and streamline installation.
2. Pre-Drywall Prep & Wall Flattening →
We shim and plane framing to correct imperfections and create flat, straight surfaces—essential for high-end Level 4 and Level 5 finishes.
5. Multi-Coats of Mud (Level 4–5 Finishing) →
Multiple coats of mud, sanding, and skim coating (Level 5) create smooth, uniform surfaces designed to perform under natural and artificial lighting.
6. Precision Masking for Primer & Paint →
All non-finished areas are carefully masked to ensure sharp lines, clean edges, and a controlled application environment.
7. Two-Coat Primer Application & Detailed Touch-Ups →
We apply the first coat of PVA primer, complete detailed touch-ups, then apply a second coat for even coverage and a paint-ready surface.
8. Interior Painting (Turnkey Finish) →
Professional interior painting is included, delivering a durable, consistent finish with one contractor—no handoffs, no delays.
4. Jobsite Protection & Floor Prep →
We remove debris and protect floors and surfaces with paper and masking to keep the project clean, organized, and efficient from start to finish.
3. Drywall Installation →
Drywall is installed with precise layout, fastening, and tight seams to ensure structural integrity and clean, consistent transitions.
9. Final Cleanup & Debris Removal
All drywall scrap, dust, and debris are removed, leaving your ADU clean, safe, and ready for final use or the next phase.
