Complete Roofing, Siding, Chimney, Gutter & Skylight Services

My son and I practice Internal Medicine and Gastroenterology together in Forest Hills and Manhattan. Arjan, who owns the company has spearheaded renovation and construction work in both offices and is currently doing a gut renovation on our Upper East Side apartment. Having done many construction projects over the years, I have a broad basis for comparison. Arjan and his team have been extraordinary in every way. The work is clean, elegant, sturdy, and timeless. The design team made efficient and aesthetic layouts that are at once practical and beautiful. The work is meticulous. Most of all the workers always arrived as promised and were clean, courteous, and cooperative. George is easy-going and avuncular. Nothing is ever a problem. We have used A&GJ Construction repeatedly and look forward to future projects.

Hiring A&GJ Construction has been the best decision we have made in a long long time. Not only did A&GJ Construction finish our project on time but under budget as well. Mr. Arjan Gjana owner/operator and Founder of A&GJ Construction was a real pleasure to work with. Arjan’s many years of architecture and engineering experience found ways to improve and save our budget. Time and time again we found ourselves relying on his expertise, honesty, and professionalism, characteristics not found in today’s new construction era. We at Cape Advisors Inc. would strongly recommend A&GJ Construction to any developer out there looking for a construction company that will take your plans and deliver what they promised. A&GJ Construction was the backbone of this project; hiring A&GJ Construction was a Grand Slam Homerun!!!!

They replaced our roof in two days flat after a storm. Fully insured, polite crew, and not a single surprise on the bill.

Called at 11 pm with a leak. They tarped it the same night and were back the next morning. That's the real deal.

Their team replaced our siding and the curb appeal jump was incredible. Crew showed up on time every day and cleaned up daily.

Honest pricing, no upsell games. They explained exactly what the chimney needed and what could wait. Refreshing.
