COMMON QUESTIONS
Frequently Asked Questions About Home Renovations in Portland
How long does a kitchen remodel take in Portland?
Most kitchen remodels in the Portland area take between 6 and 12 weeks from the start of demolition to final completion. The timeline depends on the scope of the project, whether structural changes like wall removal are involved, and how quickly materials are available. We provide a realistic schedule during the planning phase so you know exactly what to expect.
Do I need a permit for a room addition in Portland, OR?
Yes. Room additions and home extensions in Portland require permits from the Portland Bureau of Development Services. Depending on your project, you may also need electrical, plumbing, and mechanical permits. Our team handles the entire permitting process on your behalf so you do not have to navigate the paperwork yourself.
Can I stay in my home during a renovation?
For most single-room projects like a kitchen or bathroom remodel, yes, you can continue living in your home. We take steps to contain dust and minimize disruption to your daily routine. For larger whole home renovations or major structural additions, we may recommend temporary relocation for your comfort and safety, and we will discuss this with you during the planning phase.
How does your flat-fee pricing model work?
After our initial consultation and site evaluation, we prepare a detailed, itemized quote that covers every aspect of your project including labor, materials, permits, and project management. The price in that quote is your total cost. Unlike cost-plus contractors who charge for time and materials with an open-ended budget, our flat-fee model gives you complete cost certainty before construction begins.
