About Us

Do it once.

Our founders share a passion for construction, family, and faith. Each of their families came to America when they were children looking for freedom and opportunity. Dmitriy, Sergey and Vazgen have embraced the chance build a company that reflects their shared values of integrity, professionalism and reliability. With 30 years of construction experience combined, our founders had a vision to create a different kind of construction company. In 2017, Cobex Construction Group was created as a family-oriented company based on four cornerstones:


 Stress-Free Customer Experience – Many homeowners have home improvement dreams and the thought of finding a contractor they can trust can be intimidating. We utilize a low-pressure approach that provides education, options and pricing in the comfort of your home.

 Long Term Customer Relationships – We are the company homeowners can trust to make their dreams a reality, one project after another. Prioritizing customer relationships over profit margins motivates us to do whatever it takes to keep our customers satisfied.

Quality Workmanship – Since every project is our advertisement, we are obsessed with quality. Our network of superior contractors knows that if it’s not done right, it’s not done! We aim to exceed expectations EVERYTIME!

 Transparency – From your first contact with us, we will be clear about what you can expect and will communicate every step of the way, so you are never in the dark.

Cobex Construction Group creates jobs and career advancement opportunities for family members and devoted team members. Cobex is a place where people can enjoy their work, feel appreciated and embrace professional development. When a customer gives us a positive review, we all share in the moment. The founders are mindful of how blessed they are and remain devoted to sharing those blessing with others. Together, they have created a special place for customers, team members and partners.

Only The Best There Is.

At Cobex we focus on delivering the best quality products to our customers. We believe that if we won’t instal it on our own home, then we shouldn’t instal it on our customer’s homes. Bringing back the trust in the construction industry is a difficult task, we will only be able to achieve this feat by bringing you the best possible products. We are thankful for our amazing partners at Owens Corning,  Anlin Windows, Tex-Cote Cool Wall, Hardy Siding and many more !


Professionals Only

We employ the most qualified and experienced contractors, people who have been in their trade for their entire lives. Trust can’t only be gained by providing quality products, but by also providing a quality installation team. People who love what they do and have passion for their work. Throughout the years we have noticed that a lot of general contractors sub-contract out their jobs to the lowest bidders, but Cobex will not take part in such an ancient form of business. 

Customer Service

Best in the Business

If we are not your friends by the end of the project, then we have failed. Our goal is to provide the best customer service experience possible. Customer service is an important focus of ours and should be an important focus for all companies. We want you to enjoy working with us, and for there to be transparency between the company and our customers. We ask that you do not hesitate to give us a call if you have any questions or concerns!


Competitive And Always In Writing.

Cobex is definitely not the cheapest company out there. Cobex is definitely not the most expensive company out there either. Instead we focus on bringing you the quality you deserve for the prices that don’t break the bank.
