Get matched with top addition to existing structure builders in Middlesex, NJ

"Contacted Sky's the Limit to patch/repair/paint an older addition. He exceeded our expectations. The work was exceptional, his crew was clean and neat and they completed on time and on budget as promised. Could not be happier with Adrian and his team. It's rare to find an honest contractor these days. Will definitely be recommending him."

"A positive experience all around! My first renovation, I was unclear about many aspects of the contracting process, let alone the actual work that needed to be done. Ryan is an excellent communicator--a fact clear from his first visit and which helped us choose him for the job--and I felt at ease throughout the project, always on top of what was going on in my house, and able to make informed decisions along the way. Indigo delivered exactly as promised, reliably on schedule. Ryan and all his crew seemed to work efficiently and tirelessly, and were always polite and respectful of our property and privacy, in what was at times a crowded little house. We got a price we consider fair, and know was competitive. And we are very happy with the new bathroom. Looks great!"

"Perfect. No other words needed. On time. Polite. Professional. Worked like dogs all day. Knew exactly what they were getting themselves and how to get it done. I will definitely hire them again for my next project."

"The project was completed within budget and on schedule. The team was professional, responsive to accommodating changes and taking feedback."

"HORRIBLE!! Reached out to them for 4 days straight through Angi - no reply. DO NOT RECOMMEND!!"

"Great, a little slow on timing but overall great work"

"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."
