Remodeling should be exciting — not stressful. De Marco Builders handles every phase of your renovation with the same transparency, craftsmanship, and accountability Portland homeowners have trusted since 1996.
The design-build difference
Helping Your Home Realize Its Full Potential
Over time, even a home you love can stop working the way you need it to. At De Marco Builders, residential remodeling is about more than updating finishes or adding square footage — it's about bringing your home back in line with who you are today. We've been doing that for Portland homeowners since 1996, with the same team, the same standards, and the same commitment to delivering exactly what we promised.
Quality that Goes deeper
More Than A Fresh Coat of Paint
The most successful remodels are the ones where the finished space feels completely intentional — where the layout makes sense, the materials were chosen thoughtfully, and the quality of the work is evident in every detail. That outcome requires more than skilled tradespeople. It requires careful planning before construction begins, clear specifications that leave nothing to interpretation, and consistent supervision throughout to ensure the work matches what was designed.
A remodel done well also respects the existing home. New work should integrate seamlessly with the original structure — in proportion, in material quality, and in craftsmanship. When it does, the result is a space that feels cohesive and considered rather than patched together. That standard of work is what separates a remodel that adds genuine, lasting value to a home from one that simply changes its appearance. With nearly three decades of residential construction experience, it is a standard that we understand well, and apply to every project, regardless of scope.
THE PROCESS
What to Expect.
A residential remodel moves through several phases — assessment, planning, permitting where required, and construction — and the sequencing of those phases matters considerably. Decisions made early in the process have a direct impact on cost, timeline, and the quality of the finished result. A thorough assessment of the existing space, accurate scope documentation, and a realistic project schedule established before work begins are what allow a remodel to proceed without unnecessary disruption or costly corrections mid-construction.
A well-managed remodel minimizes disruption to daily life as much as the scope allows, keeps the job site clean and organized at all times, and concludes with a walkthrough that confirms every detail has been completed to the standard the project called for. That level of care and accountability is what a remodel of this significance deserves — and what our clients can count on.

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.

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.
