Our Coverage
One Standard Every City.
We serve the full Portland metro area — from inner-city neighborhoods to established suburbs. Wherever you are in the region, you get the same team, the same process, and the same commitment to quality that De Marco Builders is known for. Owner Joe De Marco and lead superintendent Diego Alvarez are involved in every project from first conversation to final walkthrough.
We're a full design-build firm, which means our architects, engineers, designers, and construction team work together under one roof — improving communication, reducing delays, and keeping costs controlled from concept to completion. And because we use a critical path scheduling approach, we consistently deliver projects up to 10× faster than the industry average without compromising craftsmanship.

WHy it Matters
Local Knowledge Saves You Time and Money.
When you work with a contractor who knows your city, you avoid the delays and missteps that come from a learning curve on your dime. We know the permit timelines, inspection schedules, and common hold-up points across every jurisdiction we serve — and we build all of that into our scheduling before a single shovel hits the ground.
We also bring established relationships with local suppliers, trusted subcontractors, and specialty trades throughout the metro. That network means faster material sourcing, better pricing, and crews who show up on time — because they're not driving in from across the state.

How do you price a project?
Every proposal from De Marco Builders provides complete cost transparency. Our estimates clearly show the construction costs, company overhead, profit, and total project cost so clients fully understand where every dollar is allocated.
Do you require a deposit?
No. Never. We do not require an upfront deposit. The first payment is due only after a portion of the contracted work has been completed.
What happens if costs change during the project?
We guarantee the contract price through project completion unless the homeowner requests additional work beyond the original scope or unforeseen structural conditions are discovered that were not visible during the initial evaluation.
Can you work within a specific budget?
Absolutely. De Marco Builders is a budget-driven builder. We work within the client’s established budget throughout the design, engineering, permitting, and construction phases. We utilize value-engineering principles to maximize quality while maintaining budget goals.
Are you licensed, bonded, and insured?
Yes. De Marco Builders is fully licensed, bonded, and insured. We maintain all required certifications and operate in full compliance with state regulations.
How do you handle unexpected issues that come up mid-project?
Unexpected issues are rare because of our extensive experience and thorough planning process. If an unforeseen issue does arise, it is addressed immediately, typically within 24 hours. We resolve issues in a code-compliant manner while protecting the project schedule.
How often will I receive updates?
Communication is one of our highest priorities. Once a client signs a contract, we maintain frequent communication throughout design, engineering, permitting, and construction. Clients receive regular progress updates, photos, and end-of-day reports so they remain informed from start to finish.
