"Anush and his team were absolutely amazing, and our porch turned out better than we expected thanks to his ideas/recommendations. The attention to detail/pride they take in their work truly stand out and far exceeded our experiences with contractors in the past. One of my favorite parts is how much I genuinely love coming home now. It completely changed the look and feel of the front of our house, and every time I pull into the driveway it makes me happy to see it. I will absolutely be recommending AVSTEP to anyone planning renovations or building a home. We already have several more projects planned for our house in the coming months, and without question we’ll be using Anush and his team again. It’s such a great feeling to know we now have a contractor we genuinely trust and can confidently call whenever we need work done. Even our neighbors have been commenting on how beautiful the front of our house looks and what an incredible job they did. Below are the before and after pictures"

"I highly recommend Bryan's Home Improvement and Handyman Services. The owner Bryan Grubb was wonderful. He and his staff assisted me in every stage of the remodeling of my bathroom. We entered a contract which they stuck by. The price to perform the remodeling was very, very fair. During the remodeling, a structural problem was found. They addressed the problem and provided me with options to correct the problem. These were structural issues which should have been addressed by their predecessors and was inconceivable that the problem could have been missed. Bryan's handymen, led by Jorge, were professional, timely, efficient, knowledgeable, artistic and neat. They did a fantastic job on my bathroom. I can't thank them enough. I will recommend them to everyone I know. I will definitely hire them again. A+++"

"Very well. Mark is extremely responsive. I had a clear vision of what I wanted to do and Mark was able to get me to a great plan with about three iterations of the plans. Also Mark's plans were approved without revision by the building department which is not easy to do where we were building."

"Everything went well and the job was done perfectly. The work was so good it was like I had a new bathroom put in. They cleaned up and left no trash for me to get rid of. I will be calling them again as soon as I can get a few more dollars. The pricing is very fair and reasonable, and I really appreciate a business that will give you fair pricing. J Bethea"

"My parents bought a new Condominium in Brooklyn are 2 years ago, and later on we decided to remodel our old bathroom and walls texture in the apt. so my mom asked me to find a remodeling company to remodel the bathroom in the apartment... I had use this Company before and  I decided to call them for an estimate...

Their estimated price was in closer to our budget and we decided to go with them..

We agreed at 28500$ for a complete remodeling, at the end we paid 300$ extra because we decided to replace the old bathtub with a new one witch was unexpected for us ...They finished the work in two weeks and my parents were very happy  with the service provided by Structure Construction...

Thanks Again

FAQs for addition to existing structure building service projects in Dayton, NJ

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.
