Seamless execution of a construction project requires a comprehensive understanding of its scope and scale, with an emphasis on meeting deadlines and adhering to budgets. To meticulously plan and execute each phase, from concept to completion, developers and homeowners require the expertise of a trusted contractor with excellent craftsmanship and a team committed to fulfilling their vision.

G&M Efestos Contracting Inc., a family-owned company with over 40 years of experience, has earned a reputation as a top contractor for residential and commercial buildings in the Pennsylvania, New Jersey, and Delaware region.

Working closely with homeowners, developers, restaurateurs, and investors, the team oversees every project phase, ensuring timely completion within budgets. Specializing in new construction and renovation services, G&M Efestos distinguishes itself through its commitment to unparalleled service and stellar craftsmanship.

The company’s edge lies in its background in the commercial construction world, with extensive experience in the hospitality industry, allowing it to execute residential projects seamlessly. An understanding of the specific requirements and demands involved in commercial projects equips the team to successfully handle residential projects flawlessly.

“Contractors with expertise in building only residential properties find it challenging to handle commercial projects. Our team of professionals comes from the commercial sector and now focuses on multifamily, condominium, and townhouse construction as well, which is a competitive differentiator for us,” says Greg Karamitopoulos, president and owner at G&M Efestos Contracting.


A comprehensive understanding of the unique requirements and complexities associated with commercial, multifamily, and residential projects allows the team to deliver impressive results. Today, clients increasingly seek reliable contractors like G&M Efestos that can value engineer a project to identify cost-saving opportunities while minimizing the time required for project completion, ensuring it stays profitable.

“From the time we win a bid, we are highly focused on finding ways to save the client money across all phases of the project,” says Karamitopoulos.

Each project is scheduled carefully with a timeline outlining the sequence of events, from demolishing existing structures and laying the foundation to framing and finishing. G&M Efestos also provides owners with a schedule of the proposed timeframe for every job, making sure they remain informed at each step. This approach streamlines the construction process and minimizes potential delays.

A challenge clients often encounter is dealing with incomplete designs. Many architects and engineers offer an understanding of the overall structure, but they fail to provide intricate details of the spaces. G&M Efestos understands that every detail matters in creating exceptional spaces. With its in-house designer, it eases the burden of decision-making for clients by collaborating with them throughout the project to finalize finishes and obtain approval ahead of time. Effective communication and regular updates keep clients informed throughout the process, fostering transparency and deeper satisfaction.

G&M Efestos prides itself on a dedicated team of project managers who have more than just theoretical knowledge and are experienced craftsmen with years of hands-on knowledge. This first-hand experience enables the team to approach projects holistically, considering both the process and the end product. Skilled in-house carpenters and designers contribute to the company’s proficiency in meeting project goals. With a keen eye for detail and problem-solving skills, the team identifies and addresses issues proactively for smooth project execution.

By consistently delivering outstanding results, G&M Efestos Contracting has positioned itself as a reliable and customer-centric contractor, excelling in the apartment and condo space.
