Our 4 Pillars That Guarantee Success For Every Project We Take On

Pillar #1
100% Open-Book Policy For Every Project

No hidden costs. No surprises. Just complete financial transparency. Unlike most builders, we give you full access to every detail of your project’s finances.

Want to see material costs? Labor rates? Contractor fees? It’s all yours. We even welcome third-party reviews of our books because we have nothing to hide.

Every dollar you invest is tracked, explained, and working towards your project’s success. This isn’t just about being open – it’s about giving you total confidence that your money is being managed with absolute integrity.

Think of it as your all-access pass to peace of mind.

Pillar #2
Our Building Block System To Prevent Construction Problems

We build to last, not to fix later. From day one, we use premium materials and proven techniques that minimize future maintenance and maximize your building’s lifespan.

We only work with elite contractors who meet our exacting standards. Why? Because quality partnerships create quality buildings.

The result? You get more than just an attractive, functional space. You get a building that stays strong with minimal upkeep, giving you peace of mind and lasting value for years to come.

Our Origin Story

Some builders learn their trade in school. Solomon Vegh was born for it. Family legend has it that as a baby, he preferred sleeping with pliers in his hand instead of a pacifier – a sign of what was to come.

In 2003, Solomon started small with a handyman business. What he discovered shocked him: while clients craved quality work, the construction industry was failing them with corner-cutting and broken promises.

He knew there had to be a better way.

In 2017, Solomon launched Cornerstone Builders with a bold vision: to transform how construction is done in Rockland County. His blueprint for success was simple: total transparency with clients, uncompromising quality standards, and true partnerships, not just projects.

Today, Cornerstone stands as a full-service construction company, bringing together elite designers, architects, and builders under one roof. Every project we touch – from home renovations to commercial builds – carries Solomon’s original promise: exceptional craftsmanship backed by absolute integrity.

Your dream isn’t just another project to us. It’s our chance to prove that construction can be different.

Mission Statement

Cornerstone Builders aims to transform the construction industry by building more than just homes – we build trust, transparency, and lasting relationships. Through exceptional craftsmanship, complete financial openness, and client education, we empower every client to be confident in their construction journey, from the smallest repair to the grandest custom home.

We don’t just want to meet industry standards. We’re here to set new ones.

Our Vision

To be the company that changes how America builds – where transparency isn’t just promised, it’s proven. We envision a construction industry where:

  • Quality speaks louder than words.
  • Trust is built before the first foundation.
  • Every client is a partner, not just a project.

We’re creating a future where clients don’t just hope for excellence – they expect it. Where understanding your build is as important as building it right. Where every decision is informed, every step is clear, and every project stands as proof that construction can be different.

Because we believed a fully informed client is an empowered client.
