Full-Service Design-Build · Est. 1996
We Build Portland's Finest Homes.
From the first sketch to the final nail, DeMarco Builders manages every phase of your project — design, permitting, construction, and beyond.
a Custom Home Built Around You
Your Vision, Built Exactly the Way You Imagined It.
Our custom homes begin with your vision — not a template, not a catalog, and not someone else's idea of what a home should be. From there, our team handles every phase of the process, translating your vision into permit-ready designs and then building it exactly as planned, from the ground up.
Every decision — layout, materials, finishes, and construction — is made with your vision at the center. The result is a home that is entirely, unmistakably yours.

Built To Last
Craftsmanship That Goes Beyond What You Can See
A custom home is one of the most significant investments you'll ever make. What separates a home that holds its value from one that doesn't isn't just the finishes you choose — it's what's behind the walls. At De Marco Builders, the same standard of quality that goes into your cabinetry and countertops goes into your framing, your insulation, your mechanical systems, and every structural decision made along the way. Because a home built correctly from the inside out is one that performs well for decades, not just on move-in day.
That level of quality doesn't happen by accident. It's the result of careful planning, experienced supervision, and a construction process that is managed closely at every phase — from foundation to final inspection. For us, quality isn't a selling point. It's a standard.
THE PROCESS
What to Expect.
Custom home construction moves through several distinct phases — design development, permitting, site preparation, and construction — each one requiring careful planning and precise execution. Clients receive a detailed project timeline and transparent estimate before work begins, establishing a clear foundation of expectations that carries through every stage of the build.
At every phase, clients receive regular progress updates and have direct access to our team whenever needed. If questions come up, they get answered promptly. If anything requires a decision, it is communicated clearly and documented before work proceeds. The goal at every phase is the same — to keep the project moving efficiently while ensuring the finished home meets the standard that was agreed upon from day one.

How long does a typical project take?
It depends on the size, scope, design complexity, permit process, and material availability. Smaller remodels may take only a few weeks, while larger custom homes or commercial projects can take several months. We use a critical path scheduling approach that allows us to complete projects up to 10× faster than the industry average without compromising quality. Before construction begins, we provide a projected timeline and keep clients informed throughout every phase.
How do you price a project?
Pricing is based on the size and scope of the project, design complexity, materials, site conditions, engineering requirements, and overall timeline. We provide a detailed, transparent estimate tailored to your goals and budget — and work closely with you throughout planning to maximize value and avoid unexpected costs.
Do you require a deposit?
Yes, in some cases we do require a deposit, depending on the size and nature of the project. However, our typical process is progress-based billing, where clients are billed as each phase or scope of work is completed.
At De Marco Builders, we believe in delivering results first before requesting payment whenever possible. This approach reflects our confidence in the quality of our work while also giving our clients greater peace of mind throughout the construction process. Any required deposits or payment schedules are discussed clearly and agreed upon before the project begins.
What happens if costs change during the project?
Project costs typically remain consistent with the original estimate unless you request changes to the scope of work, or there are significant shifts in material pricing due to market conditions beyond our control. Any changes are communicated clearly and promptly before we proceed, and documented through a written change order outlining the updated scope, pricing, and schedule — so you approve everything before additional work begins.
Can you work within a specific budget?
Yes. At De Marco Builders, we work closely with our clients to understand their budget goals and priorities from the beginning of the project. Our team helps guide design choices, material selections, and construction options to maximize value while maintaining quality craftsmanship.
Through careful planning and transparent communication, we strive to create solutions that align with both the client’s vision and budget without compromising the overall integrity and functionality of the project.
Are you licensed, bonded, and insured?
Yes. De Marco Builders is fully licensed, bonded, and insured. We are committed to maintaining professional standards, quality workmanship, and compliance with all applicable building regulations and safety requirements, giving our clients confidence and peace of mind throughout the construction process.
How do you handle unexpected issues that come up mid-project?
If unexpected issues arise during the project, we address them promptly and communicate with the client right away. However, we rarely experience major unexpected issues because we carefully plan and manage each project to help prevent unnecessary problems before they occur.
Our team works to find practical and cost-effective solutions while minimizing delays and keeping the project moving efficiently. Any necessary changes are discussed and approved before additional work proceeds.
How often will I receive updates?
Clients receive regular updates throughout the project, including progress, scheduling, and any important developments. We believe clear and consistent communication is essential to keeping projects running smoothly and ensuring our clients stay informed every step of the way.
