Basement Drywall Installation in Portland, OR
Moisture-aware, mold-resistant, finish-ready drywall for Portland basement remodels.
Basements need drywall detailed for moisture. Portland's rainy climate and old concrete foundations mean the wrong board or missing air gap will show up as mold or stains inside two years. We install basements to last.
What basement drywall installation really involves
Basement drywall is not just walls with a lower ceiling. It's an assembly that has to tolerate seasonal humidity, occasional weeping foundation walls, and the fact that basement air moves differently than upstairs. Our standard scope specifies mold-resistant paperless drywall or MR gypsum at the bottom 24–48" of any perimeter wall, an air gap or foam-board buffer against the foundation, and paperless corner beads in bathrooms and utility areas.
Framing usually comes before we're on site. We coordinate closely with the framer so top plates, penetrations, blocking for towel bars and TV mounts, and insulation are all correct before we start hanging. We hang the board tight, screw to spec, tape with paper, three-coat mud to Level 4 (Level 5 available for accent-lit great rooms), texture as you prefer, then prime and paint.
Bathrooms, laundries and mechanical rooms get paperless or moisture-resistant board and paperless corner beads throughout. Ceilings get a proper transition detail where they meet stair openings and mechanical soffits so cracks don't develop as the house moves.

Frequently asked questions
Do I need moisture-resistant drywall in my whole basement?
Not everywhere — but at minimum in bathrooms, laundries, mud rooms and the bottom 24–48" of perimeter walls. We recommend paperless drywall in any zone that could get intermittent moisture.
Should the basement have a drywall or drop-tile ceiling?
For a finished living-space feel, full drywall — with access panels at critical valves. Drop tile is faster and cheaper but reads utility.
How much does basement drywall installation cost in Portland?
A typical 800–1,200 sq ft basement rock-through-paint runs $12,000–$25,000 depending on room count, ceiling detail and finish level. Free itemized estimate.
Do you insulate the basement walls?
We don't install insulation ourselves. We coordinate with your GC or insulator so wall assemblies (foam board, batts, vapor detailing) are correct before we hang board.
Can you finish basement bathrooms including tile substrate?
We install drywall and paperless corner beads; tile substrate (cement board) at wet walls is installed by us or the tile setter depending on scope.
How long does a full basement drywall project take?
Typical 800–1,200 sq ft basement is 3–5 weeks from first day of drywall through final paint.
Do you handle egress window returns?
Yes — drywall returns around egress windows finished and painted.
Do you work with GCs on basement remodels?
Yes — we sub drywall, texture and paint on residential basement remodels for several Portland-area GCs.
