Q&A
We live in an older San Bernardino home and are adding a major kitchen remodel. Should we be concerned about our electrical system?
Yes, this is a common and important consideration. Many older homes in our area have electrical panels that aren't designed for today's appliance loads. As part of our process, we conduct a thorough electrical inspection before starting any major remodel or addition. We can identify if a panel upgrade is needed to safely support your new kitchen, ensuring your home's infrastructure is safe and up to code for modern living.
What is your process for building an ADU or guest house in San Bernardino?
We manage the entire process from concept to completion. It starts with a consultation to understand your goals—whether it's for family, rental income, or a home office. We then handle all planning, securing necessary local permits, and construction. Using our experience with modular and manufactured home techniques, we work efficiently to create a durable, high-quality accessory dwelling unit that adds value and function to your property.
How do you ensure a remodeling project stays on track and within budget?
Transparency and planning are key. We begin with a detailed scope and estimate, and we maintain open communication throughout the project. You'll be kept informed of progress and any unforeseen issues that may arise, which we address with practical solutions. Our decades of experience allow us to anticipate challenges and manage timelines effectively, aiming to deliver your remodel smoothly and as agreed.
