Built for the.
Rose City.
From custom homes in the West Hills to kitchen renovations in Sellwood, commercial buildouts in the Pearl District to ADUs in Alberta Arts — De Marco Builders has been building and renovating across Portland’s neighborhoods for nearly three decades.
Who We Are
Craftsmanship That Matches The City.
Portland has a distinct architectural character — from the craftsman bungalows of Ladd’s Addition to the contemporary builds going up in the West Hills. Building here well means understanding that character, respecting what’s already there, and adding to it in a way that lasts. That’s not something you learn from a manual. It comes from experience, attention to detail, and a genuine commitment to getting it right.
De Marco Builders brings nearly three decades of construction experience to every Portland project. We know what quality looks like at every phase — from the framing to the finish work — and we hold our crews to standards that go well beyond what’s required. The result is work that doesn’t just pass inspection. It’s work that holds up, looks right, and reflects well on the neighborhood it sits in.
That level of craft doesn’t happen by accident. It comes from a team that takes pride in the outcome, a process that catches problems before they become expensive, and an owner who is personally invested in every project we take on. When you hire De Marco Builders in Portland, you’re getting a contractor who treats your home or building the way they’d want their own treated.

local Expertise
Rooted in Portland. Built for Portland.
Portland isn’t just where we work — it’s where we’re invested. We know the neighborhoods, the permit offices, the inspectors, and the local suppliers who can get materials on time without the markups that out-of-area contractors pass along to their clients. That familiarity doesn’t just make the process smoother. It makes the end result better.
Working exclusively in the Portland metro means every project benefits from relationships we’ve built over years — with trusted subcontractors, specialty trades, and local suppliers who share our standards. When you hire a contractor who knows your city, you skip the learning curve. You get a team that hits the ground running, understands the local building conditions, and knows how to navigate the permitting process without losing weeks to avoidable delays.
That local focus is a deliberate choice. We could take on projects further out, but we don’t — because being genuinely embedded in a market makes us better at what we do. Portland’s homeowners and business owners deserve a contractor who is as invested in this community as they are. That’s what we bring to every project, in every neighborhood, across the entire metro area.

WHY DE Marco
Why Portland Homeowners and Businesses Choose Us.
Portland has no shortage of contractors. What it has a shortage of is contractors who show up on time, price jobs honestly, communicate consistently, and deliver work that holds up years later. That’s the gap we’ve been filling for nearly three decades — and it’s why most of our new clients come from referrals rather than advertising.
We’re not the biggest firm in the metro. We don’t want to be. We’re selective about what we take on because we’d rather do fewer projects exceptionally well than more projects at an average standard. Every project gets the direct involvement of ownership, a dedicated project manager, and a crew that’s been vetted and worked with us long enough to know what our standards look like.
And when something comes up — because something always does on any construction project — we deal with it directly, transparently, and without making it the client’s problem. No runaround, no finger-pointing, no surprise invoices. Just a straight answer and a solution. That’s not a marketing promise. It’s how we’ve stayed in business this long.

FAQ
Common Questions.
Can’t find the answer you’re looking for? Reach out and we’ll get back to you within one business day.
Do you offer free estimates?
Yes. Initial consultations and estimates are always free. Reach out and we’ll get back to you within one business day.
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.
