Whether you're building a new home, renovating a room, or dealing with water damage, chances are drywall is involved. But what exactly is it — and why does quality installation matter so much?
What Is Drywall?
Drywall — also called gypsum board, sheetrock, or wallboard — is the standard interior wall and ceiling material in modern construction. It consists of a gypsum plaster core pressed between two layers of thick paper. Once installed and finished, it creates the smooth, paintable surface you see in virtually every home and commercial building.
Before drywall became the norm in the 1950s, walls were built using a much slower and more expensive process called wet plaster, which required skilled plasterers and days of drying time. Drywall revolutionized the construction industry by cutting installation time dramatically while delivering a durable, fire-resistant wall system.
Did you know? The brand name "Sheetrock" is so widely used it has become a generic term — but Sheetrock is actually a registered trademark of USG Corporation. All Sheetrock is drywall, but not all drywall is Sheetrock.
Types of Drywall
Not all drywall is the same. Different environments and uses call for different types:
Standard Drywall
The most common type, used in living rooms, bedrooms, and hallways. Comes in ½" (most common) and ⅝" thickness.
Moisture-Resistant
Designed for bathrooms, kitchens, and laundry rooms. Often called "green board." Resists humidity but is not fully waterproof.
Fire-Resistant (Type X)
Contains glass fibers for added fire resistance. Required by code in garages, utility rooms, and multi-family shared walls.
Soundproof Drywall
Multi-layered with viscoelastic polymer to absorb sound. Ideal for home theaters, recording studios, or shared walls.
The 5 Levels of Drywall Finish
Drywall finishing is graded on a scale from Level 0 to Level 5. The level determines how smooth the final surface is — and directly affects the quality of your paint job.
- Level 0 — No finishing. Boards are hung but not taped. Temporary construction only.
- Level 1 — Tape embedded in joint compound. Attics or concealed spaces.
- Level 2 — One skim coat over tape and screws. Garages or areas that will be tiled.
- Level 3 — Two coats of compound. Good for heavy texture or flat paint.
- Level 4 — Three coats. Standard for most interior walls with eggshell, satin, or semi-gloss paint.
- Level 5 — Full skim coat over the entire surface. The premium finish for high-gloss paint, critical lighting, or flawless walls. This is what we specialize in.

Pro Tip: Always request Level 5 if you plan to use high-sheen paint or if your walls receive raking light (light hitting the wall at a low angle, like near windows). Lower finish levels will show every imperfection under those conditions.
Common Drywall Problems
Even well-installed drywall can develop issues over time. Here's what to watch for:
- Nail pops — Screws push through the surface as lumber dries and shifts. Easy to fix before painting.
- Cracks — Minor hairline cracks at corners are normal settling. Large or recurring cracks may indicate structural movement.
- Water damage — Stains, soft spots, or bubbling paper indicate moisture intrusion. Fix the source before patching.
- Holes — From doorknobs, anchors, or accidents. Small holes can be DIY-patched; larger ones need proper backing and professional finishing to blend in.
When to Call a Professional
Small cosmetic repairs can be a DIY project, but these situations call for a professional drywall contractor:
- Damage larger than a few inches in diameter
- Any water damage (always fix the source first)
- Full room installations or new construction
- Finish work where paint quality matters — Level 4 or Level 5
- Textured ceilings (popcorn removal, orange peel, knockdown matching)
