Benefits of hiring a Project Manager over a General Contractor
At Sonoma Custom Renovations, we take a project management approach rather than operating as a traditional general contractor—and the benefits to homeowners are significant. Our method ensures greater control, transparency, cost savings, and efficiency, giving you a smoother and more rewarding renovation experience.
Lower Costs
General contractors typically charge a markup of 50-60% or more on materials, subcontractor work, and labor, adding significant costs to your renovation. By using a project management model, we eliminate these unnecessary markups. Instead of funneling everything through a general contractor who profits on each layer of your project, we directly manage subcontractors and material procurement, allowing you to get the best pricing without hidden fees.
Full Transparency
With a general contractor, you often receive a lump-sum quote with limited insight into how costs are allocated. Our project management model provides full transparency, breaking down labor, materials, and other expenses so you know exactly where your investment is going. You’ll have access to budgets, timelines, and contractor bids, giving you peace of mind and ensuring you’re paying fair market value for every aspect of your renovation.
Faster Timelines
General contractors typically juggle multiple projects, which can lead to delays, miscommunication, and a lack of accountability. Our project management approach prioritizes your renovation, coordinating every aspect of scheduling with precision. We use efficient planning, direct contractor oversight, and proactive problem-solving to keep your project on track. With clear timelines and hands-on management, we ensure your renovation is completed on time and with fewer disruptions.
Higher Quality Work
Rather than relying on a general contractor to oversee everything, we personally manage each phase of the project, ensuring quality craftsmanship at every step. Our hands-on approach means that we hold subcontractors accountable, conduct regular inspections, and guarantee that every detail meets the highest standards.
Customization & Control
Working with a general contractor often means making compromises—they might push certain vendors, materials, or designs that suit their business interests rather than your preferences. Our approach puts you in control. We help guide you through design and material selections while giving you access to a wider range of vendors, suppliers, and subcontractors, ensuring your renovation truly reflects your style and needs.
