What Our Clients Say

"Arm Prime Construction did an amazing job remodeling our entire home, including new floor tiles, LVP flooring in the bedrooms, bathroom tiles, tub, shower, sliding shower doors and accessories, mirror LED lighting, recessed lighting, fresh paint, a new exterior door, kitchen cabinets, countertops, and sliding closet doors. They patiently guided us through the process, helped us choose materials, and clearly outlined every upgrade from the start. Their communication, craftsmanship, and attention to detail exceeded our expectations. We highly recommend them for any full house remodel projects"

- Raj K. ★★★★★

"As a new homeowner, I requested four different quotes for my home remodel. Arm Prime Construction was neither the cheapest nor the most expensive option, but they were clearly the most professional and trustworthy. From the beginning, their team guided me through every step of the process, helped with design decisions, and ensured each choice added real value while staying within my budget. The quality of workmanship was exceptional, with great attention to detail and pride in their craft. Communication was clear and responsive throughout the project, and even after completion, the team continued to provide support. That level of care is rare and truly appreciated. I highly recommend Arm Prime Construction to anyone looking for quality work, honest pricing, and a team that genuinely cares about their home."

- Jonathan L. ★★★★★

"It is with sincere pleasure that I highly recommend Arm Prime Construction, General B Contractor, for any ADU project. Narek and his team managed everything flawlessly—from permits and inspections to subcontractors and construction. The team was professional, organized, and communicative at every stage. We couldn’t be happier with the results and now enjoy having my parents live right next to us while significantly increasing our home’s value."

- Michael S. ★★★★★
