How Big?

Determine the scope of your project. If you plan to paint a single room, then DIY may be best. If you want to redo the color scheme, fabrics, and furnishings in your entire house, then calling in an interior designer or decorator might make more sense. There is a difference between an interior designer and a decorator, and it all comes down to formal education and credentialing. A designer may pursue credentials from an organization like the National Council for Interior Design Qualification and they often work hand in hand with architects and builders. Decorators focus primarily on aesthetics. Choose the right trade for your job.

How Extensive?

If you have major plans, like removing walls or replacing an outdated kitchen or bath, call in the pros. In fact, for some large projects, local requirements may dictate using a professional builder, architect, or designer. Experienced and licensed professionals can guide you through extensive makeovers.

“I’m an advocate for transparency and working closely together with the architect, the designer, and the builder early on,” says Holly Hollenbeck, CEO and principal designer of HSH Interiors, a San Francisco Bay Area firm.

How Much?

Do you have the budget and time to complete the project? You may have free time to devote to your makeover, or no time at all. Maybe you have a stash of cash saved or are scrambling for the funds. Both considerations will impact your ability to afford professional help. “Speaking with professionals early on gives you a realistic sense of pricing and timeline from the start,” says Hollenbeck.

What to Expect?

If you decide to call in a pro, what’s next? The sidebar addresses choosing a tradesperson; but once you do, what should you expect from them? There should be a signed contract (before any work commences) that outlines terms—including scope, payment, and schedule. A contract protects both parties—just in case.

Have a thorough discussion of your design goals and what you want to achieve with your project. If it’s solely design, this might include measurements and a review of your inspiration images or Pinterest boards, showing what you like and don’t like. “Clients find it hard to use words to describe what they want. If they have imagery, it’s easier to see what they want and to talk about it,” says Hollenbeck.

The designer or architect should provide concept or mood boards that visualize the end product. Tweak anything that doesn’t align with your vision or budget. If your project involves demolition or construction, that should start next. Once you’ve agreed to the final concept or set of plans, it’s time for purchasing and installation. For extensive projects, Hollenbeck offers this advice: “I encourage clients to work with someone who will provide a Gantt chart or calendar showing project progression and realistic timeline expectations.”

Throughout the entire process—whether working with a professional or doing it yourself—you should prioritize clear communication and accurate deadlines for when steps will be completed within budget for project success from start to finish.
