Despite being the simplest ceiling type, it is the least forgiving of joint work, because there is no architectural detail to distract from a shadow line. A flat ceiling has nowhere to hide. There is no coffer, no tray, no angle change to break up the plane or draw the eye. It is one continuous surface, and any variation in it is the only thing there is to see. That means the fundamentals carry the whole job: board of the right thickness, fasteners at the right spacing and depth, joints landed on framing where possible, and feathering wide enough that no transition casts a shadow. ## Why this matters - Board thickness matched to the framing span - Joint layout planned to minimise butt joints in open areas - Wide feathering so no shadow line forms - Plane verified with a straightedge, not by eye ## Our Process 1. **Assess the Ceiling**: We check framing spacing, plane, existing condition, and whether moisture has been involved before quoting anything. 2. **Written Scope**: Clear estimate covering board type, finish level, texture, protection, and a realistic schedule. 3. **Protect the Room**: Ceiling work drops debris across the entire room, so floors, furniture, and fixtures are fully covered before we start. 4. **Install and Finish**: Board hung with correct fastening, joints treated and feathered wide, then textured or finished smooth as specified. 5. **Verify Under Raking Light**: We check the finished ceiling from the direction of every window, because that is where the raking light comes from. ## What's Included - Joist spacing and plane check - Room protection - Board installation and fastening - Joint treatment with wide feathering - Sanding and texture or smooth finish - Raking light verification ## Frequently Asked Questions ### Can a flat ceiling be finished smooth? Yes, and it requires a Level 5 finish. A smooth ceiling under raking light is the single most demanding surface in residential drywall, so it needs a full skim coat rather than a Level 4 base. We will be direct about what that involves before you commit to it. --- **Hanenburg Drywall** 12 Elksford Ave, Irvine, CA 92604 Phone: (949) 446-1300 Email: info@hanenburgdrywall.com Hours: Mon to Fri, 8:00am to 4:00pm Serving all of Orange County with no travel surcharge.
