Common Questions

We're adding a bedroom and our breakers keep tripping. Can you handle both the construction and the electrical upgrade?

Absolutely. This is a common scenario in Montclair homes. As a licensed general contractor and electrician, Sapphire Builders manages the entire project. We'll design and build your bedroom addition while simultaneously assessing and upgrading your electrical panel and circuits to handle the new load, preventing those frustrating trips and ensuring safety.

During our kitchen remodel, we want to add more outlets and modern appliances. Will this overload our current system?

It's a valid concern. Modern kitchens demand significant power. Our team first evaluates your home's existing electrical capacity. We often recommend and perform panel upgrades or dedicated circuits as part of the kitchen remodeling process. This prevents overloads, safely powers your new appliances, and brings your Montclair home up to current electrical standards.

For a garage-to-ADU conversion, do you address the wiring and electrical needs for a full living space?

Yes, this is a core part of the job. Converting a garage into an accessory dwelling unit (ADU) requires a completely new, independent electrical system. We handle everything from installing a new sub-panel and dedicated circuits for kitchenettes and laundry to ensuring proper lighting and GFCI/AFCI protection, resolving the common electrical limitations of older garage wiring in Montclair.
