"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

"Great Job by Golden Mega Group! I just completed a much needed renovation of my apartment that included 2 bathroom, kitchen, 3 bedrooms and new flooring. The GMG team did an excellent job. From getting approval with my building management, through design and execution, the project went smoothly. My designer was amazing and I love my new kitchen so much that I'm cooking again! My project manager kept me informed and kept the project moving along, even when we hit some bumps in the road. I love my new space! I definitely can recommend Golden Mega Group!"

FAQs for addition to existing structure building service projects in Bayside, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
