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.

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.
