We had a great experience with Cornerstone Building. The contractor, Arnie, was very knowledgeable, easy to talk to, and made the whole process smooth. He took care of everything — even the little details I wouldn’t have thought of myself. We had some cabinets painted and some replaced, and everything turned out great. The quality of work was excellent, and I would definitely recommend them!

Arnie installed a tiled kitchen backsplash that is beautiful and exactly how I wanted it to look. He is very knowledgeable and helpful with what is needed for a home improvement project. His work exhibited high-quality craftsmanship. He was also punctual and easy to communicate with.

I have worked with Arnie for years and his experience in construction planning, design, production management, execution and the financial aspect of it all is unmistakable. His experience building ranges from small remodels to 20 story condominium complexes. His experience managing property is even more vast and this well rounded knowledge is priceless when it comes to designing a build because he knows the outcomes of your decisions and has seen it first hand. There aren't many people with this depth of knowledge and background. I highly recommend Arnie Garcia if you're planning to build something special.

Matthew Lamz Google review · May 2026

As a business owner who’s had the pleasure of working with Arnie and his team at Cornerstone, I can’t recommend them enough. Arnie is honest, incredibly knowledgeable, and a hard worker. His dependability and attention to detail, along with a talented team of driven, experienced personnel make Cornerstone stand out every time. If you want a construction partner you can trust, Cornerstone is the one.
