Built for bEAVERTON
Thirty Years of Construction Experience, Right Down the Street.
Our commercial work runs on the same standards as everything else we build — a fixed price, a real schedule, and one team accountable from the first walkthrough to the final inspection. That track record, built since 1996 across the Portland metro, carries straight over to office buildouts, tenant improvements, and ground-up commercial builds in Beaverton.
If you need a commercial contractor in Beaverton who shows up, communicates clearly, and delivers what they promised, you're in the right place.
Local Knowledge, Real Advantage
We Know Washington County's Commercial Side Too.
There's a real difference between a contractor who works in Beaverton and one who knows it. We're familiar with Washington County's permitting timelines and the range of commercial building conditions across the city — from office parks near Progress Ridge to retail and mixed-use spaces closer to downtown.
That knowledge keeps commercial projects on schedule and protects your budget from the delays that catch less experienced contractors off guard.
THE PROCESS
What to Expect.
Commercial construction moves through several distinct phases — pre-construction planning, permitting, site preparation, and construction — each requiring precise coordination to stay on schedule and on budget. In Beaverton, that planning phase matters even more, since building codes and permit requirements need to be worked out thoroughly before anything breaks ground.
Once construction is underway, expect consistent communication, documented change management, and a job site maintained to a professional standard throughout. Commercial projects often involve active businesses or time-sensitive openings — coordination that goes beyond standard construction practice.

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.
