Let's Get Started!

To get started on exploring our services, we encourage you to schedule a complimentary, no-obligation Initial Zoom Consultation. Please contact us using the form below. This consultation serves not only to provide you with detailed information but also as an opportunity for us to learn about you and your specific project needs, and to discuss how we can best assist you in fulfilling those needs.  This consultation will be with A'mia Michele, your GC.

Our philosophy is rooted in educating our clients, regardless of whether our services align with your budget. We aim to ensure that, through this initial overview and presentation, our clients feel more equipped and informed to embark on their construction project. It's important to us that you're able to ask the right questions and feel confident in your understanding of what taking on a construction project entails, empowering you to make the best decisions for your unique situation.


Here are some answers to our most common questions. If you have any other inquiries, please don't hesitate to call us!

  1. Are you licensed?  Yes, we are fully licensed, bonded, and insured. We hold a General B license (#1120255). You can find more information on our qualifications with the state board at

  2. Do you require deposits?Yes, we require a $1,000 project retainer on all jobs, along with a signed estimate with basic contract terms. A full contract is available on our website under Terms and Conditions.

  3. How soon can you start our project? For projects requiring permits, we schedule them once a contract is signed and the deposit is paid. Typically, we start within a week after permits are processed. For remodels and jobs without permits, we can discuss a start date based on availability. Kitchen and bathroom remodels are scheduled one project at a time and typically take 2-3 weeks from demolition to completion. ADUs are scheduled simultaneously, with no trade overlap on larger projects.

  4. How long does it take to build a room addition? Room additions take approximately 6-8 weeks to complete once permits are acquired.

  5. Do you handle plans and permits for custom homes and room additions? Yes, we can manage all permitting if needed. We are familiar with the process and recommend having us handle this portion. We also collaborate with several architects and engineers who can assist with plans.

  6. How long do permits take to acquire? Permits are often the biggest hurdle. Room addition and ADU permits usually take 3-4 months, while custom home permits can take 6 months to 1 year. Current city backlogs can extend this timeline.

  7. What does an ADU or room addition cost? Prices start at $300 per sq. ft. for new construction. Garage conversions start between $200 to $250 per sq. ft. There are many variables, but this provides a realistic idea of the cost.

  8. Do you help with financing? Yes, we can assist with financing. Most clients use home equity (HELOC) or refinance options for better rates. We work with a direct lender whom we can refer you to.​​

  9. Do you issue change orders? Change orders occur only if there is a change in the scope of work, time, or materials. All changes are approved in writing first. Our detailed contracts ensure no surprise bills at the end of any project. We provide out-the-door pricing to avoid any unexpected costs.

  10. Do you have references? Yes, we have many references available. We build strong relationships with our clients and primarily work through word-of-mouth recommendations.

  11. Do you work on the jobs daily?Yes, we are on every job Monday through Friday. We limit ourselves to a maximum of one remodel job and three new construction projects at a time, allowing you to work directly with us, the owners.

  12. Do you subcontract work?We are a small company and handle most work ourselves, except for specialized trades like roofing, plumbing, HVAC, and electrical. We believe in having experts for each trade to ensure the highest quality. We are finished carpenters by trade and start at the insulation phase.

  13. Do you offer a warranty?Yes, we offer a 1-year warranty on all projects as required by law. This includes plumbing, electrical, HVAC, roofing, etc. We strive for the best quality and will always address and fix any issues.

  14. Do you offer free estimates? As of 2025, all estimates have a $150.00 fee. If we are hired for the project, this amount will be applied to the project. If not, the fee covers the time spent on estimating. This policy helps filter out those seeking advice without intending to hire us. In certain situations, we may waive this fee at our discretion.
