Maximize your home’s potential with a garage conversion from Cestarollo Construction. Serving the North Bay and Wine Country, we transform underused garages into comfortable, stylish living spaces — from home offices and guest suites to full accessory dwelling units (ADUs).





You’re already busy enough as it is. We want to make this as easy as possible for you and it basically boils down to three steps:

You can call our office or fill out our website form to request an estimate. We'll talk over your project and schedule a time for us to assess the property, take measurements, and listen to your ideas.

We'll meet you at your property, take pictures, measurements, show you samples and talk over your project with you.

After you approve your quote, we will request a deposit to buy your materials and schedule your project. After that, there's nothing left to do except count down the days until we bring your new living space to life.
Whether it’s a remodel, addition, ADU, or new build, we’re ready to help. Get in touch today—we’ll connect shortly to outline scope, budget, and timeline.
