"Exceptional Work and Professionalism Justin from Innozign Contracting did an outstanding job building a bathroom in my mother’s home. He is professional, detail-oriented, and committed to high-quality work. From the start, he listened carefully, created a solid schedule, and stuck to it while ensuring everything was done to perfection. His kindness, patience, and adaptability shined through as he worked with my mom to complete the job, making the process smooth and stress-free. The finished bathroom looks fantastic, and I highly recommend Innozign Contracting to anyone looking for a skilled and reliable contractor! "

"Gary is the epitome of trash, he will use his job title of Fire department chief to persuade you that he is for the community and the people. He has not held up his end of the bargain and quite frankly i think he took advantage of my elder mom and crippled father. He fell short on nearly everything- he hasn?t come back to rectify any of the problems that were brought to his attention and at this time nearly everyone in my house hold is walking in the kitchen with shoes and slippers because the tiles he layed down are cracked and the grout didn?t last more than a month !! He has lied on several occasions and said someone would be here. I have went to his office on multiple occasions as i work across the street. His son told me someone would be back in a month to rectify. Nothing is more disappointing than putting your savings or hard earned money towards something faulty. Gary if your reading this i have absolutely no clue how you sleep at night "

"We hired Carlos Herrera of Rioza Construction in Feb 2024 for a major renovation and second-story addition under a Fannie Mae 203K loan. The home was move-in ready?just small for our family. Now it?s severely damaged from partial excavation, demo, and unnecessary removal of molding and walls. After a year-long variance process, in October of 2025 we were ready to build, Rioza demanded an extra $40K for ?inflation.? We asked for an accounting of the $84K advanced for materials?none provided. Quotes passed off as receipts were confirmed fraudulent by suppliers. No materials delivered, no phases completed, and we failed foundation inspection. HUD consultant documented everything; bank refused to release additional funds to Rioza Construction. Work has stalled for 6+ weeks, contractor name on Home Improvement license not Carlos Herrera's, belongs to someone we?ve never met. BUYERS BEWARE: Do NOT hire Rioza Construction. Verify licenses, demand receipts, and proceed with extreme caution."

FAQs for addition to existing structure building service projects in Princeton Junction, 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.
