About the C-2 — Insulation & Acoustical License
The C-2 Insulation and Acoustical contractor license covers the installation of insulating and acoustical materials for thermal, sound, and fire protection purposes. This includes installing insulation in walls, attics, and crawl spaces, as well as acoustical ceiling tiles and soundproofing systems. With California's strict energy efficiency requirements (Title 24), C-2 contractors play a vital role in helping homes and businesses meet building codes and reduce energy costs. Proper insulation can significantly lower heating and cooling bills while improving indoor comfort. When hiring a C-2 contractor, ask about R-value recommendations for your climate zone, the types of insulation materials they use, and whether they perform energy audits. Quality insulation work is one of the best investments homeowners can make for long-term energy savings.
About the C-6 — Cabinet, Millwork & Finish Carpentry License
The C-6 Cabinet, Millwork and Finish Carpentry license covers the fine woodworking and finishing touches that define a home's character. C-6 contractors build and install custom cabinetry, trim work, crown molding, wainscoting, built-in shelving, and other decorative and functional wood elements. This trade requires precision craftsmanship and an eye for detail, as finish carpentry is highly visible and must meet exacting standards. Whether you're renovating a kitchen with custom cabinets or adding architectural details throughout your home, a skilled C-6 contractor can dramatically improve both the appearance and value of your property. When selecting a C-6 contractor, ask to see examples of their previous work, discuss material options and wood species, and get a clear understanding of timelines since custom work often takes longer than standard installations.
About the C-9 — Drywall License
The C-9 Drywall license covers the installation, taping, texturing, and finishing of drywall (also known as sheetrock or gypsum board). Drywall is the standard interior wall and ceiling surface in modern construction, and the quality of its installation directly affects the appearance of a finished room. C-9 contractors handle everything from hanging sheets to applying final textures and finishes. Different projects require different finish levels, from basic garage walls (Level 1-2) to smooth, paint-ready surfaces (Level 4-5). Specialty applications include moisture-resistant board for bathrooms, fire-rated assemblies, and soundproof installations. When hiring a C-9 contractor, specify the finish level you expect, discuss texture options, and ask about their process for minimizing dust. Quality drywall work is essential for a professional-looking final result.
