A PASSION FORGED FROM THE START

Our Founder’s Story

Solomon Vegh’s road to construction didn’t begin with formal training; it began in childhood, with a story his family loves to tell: as a baby, Solomon famously fell asleep with a pair of pliers in his hands instead of a pacifier.

Today, every Cornerstone project—whether a home renovation or a commercial build—reflects Solomon’s dedication to integrity, transparency, and the highest standards of craftsmanship, giving clients the peace of mind that their investment is secure.

WHO WE ARE

Two Decades of Building Trust in Rockland County

Every great builder has an origin story. Ours began in 2003 with a simple handyman service and an uncomfortable truth: the construction industry was failing its clients. While fixing homes across Rockland County, we witnessed firsthand how corner-cutting and poor communication left homeowners frustrated, disappointed, and stuck with projects that wouldn’t stand the test of time. In 2017, Solomon Vegh decided enough was enough. He founded Cornerstone Builders with a revolutionary idea: what if construction could be completely transparent? What if every client could understand exactly what they were getting and why? This vision, backed by an unwavering commitment to quality and a genuine ‘win-win’ philosophy, has transformed how Rockland County builds.

Your Complete Construction Partner

Today, Cornerstone delivers expert construction solutions across residential, commercial, and industrial projects. But we’re more than just builders – we’re your partners in creating spaces that last.

Here’s what makes us different:
• We listen first, plan second, and build third
• Every decision is explained, every cost is clear
• Quality isn’t just promised – it’s proven at every step
• Your vision drives the project, our expertise makes it reality

From the first sketch to the final walkthrough, you’ll experience construction the way it should be: transparent, trustworthy, and built to last.
