A DIFFERENT KIND OF CONTRACTOR
Three Decades. Every Type of Build
Three decades in Portland construction means we've seen every type of project, every type of challenge, and every type of client. Custom homes, commercial buildouts, whole-home renovations, ADUs, insurance restoration — we've done it all, and we've done it long enough to know exactly what each type of project requires to go right.
That experience shows up in ways most clients don't expect. It's in how we price a job — accurately, the first time. It's in how we schedule — building around permit timelines and inspection windows before they become delays. It's in how we problem-solve when something unexpected comes up mid-project, which it sometimes does. Experience doesn't prevent every problem, but it means we handle them without drama.
What hasn't changed in thirty years is the standard. The same level of care that went into our first project goes into every project today. Different scope, different client, different city — same team, same process, same expectation of excellence from start to finish.

Service Area
We Build All Across the Portland Metro.
From inner Portland neighborhoods to the suburbs of Lake Oswego, Beaverton, West Linn, and beyond — we've built and renovated throughout the metro area. Knowing these cities, their permit offices, their inspectors, and their neighborhoods makes us faster and more effective on every project we take on.
We work exclusively in the Portland metro so that every project benefits from that local knowledge — no learning curve, no out-of-area markups, no excuses about being too far out. If you're in the region, we know your city, and we're ready to build in it.
That focus also means established relationships with local suppliers, trusted subcontractors, and specialty trades throughout the area. Better sourcing, better pricing, and crews who show up on time because they're not driving in from across the state.
WHY SPEED MATTERS
Fast Builds. Three Decades of Proof.
Most Portland contractors drag projects out for months longer than necessary. Not because the work demands it — because they lack the systems to manage it. DeMarco Builders has spent three decades perfecting a critical path build process that consistently delivers custom homes faster than the industry standard.
Less rent overlap
Fewer months paying rent while your home is being built.
Less disruption
Less time living out of boxes and waiting on your life.
Lower material risk
Less exposure to mid-build material cost increases.
30-year track record
Not a promise — a record built since 1996 by the same family.

Common Questions.

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.
