"Roberto and his team helped us select, paint, and install a large custom french door for our home office. Roberto understood our vision, made the process simple, and handled the project efficiently. Roberto was quick to respond, and showed up exactly when he said he would to make sure his team was on time and understood what we wanted. We are so happy with the way the door came out, and highly recommend Roberto and his team at Monk's."

"Tecnobuild is fantastic! Theo and his team are relentless about quality. They want your renovation dreams to come true and they work very hard to make it happen. They are flexible and will work around your schedule. They work with the township on permits and inspections. They involve the homeowners in every step of the work to make sure everything meets your expectations. We have a beautiful bathroom we can be proud of at a reasonable price. We've used Tecnobuild several times and wouldn't hesitate to hire them again."

"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."

"If I could give 10 stars, I would. Aaron and team made both the planning and building process of our addition seemless. We we're provided consistent communication throughout each step and they were committed to completing our project by our desired timeline. They truly were a pleasure to work with and they did a beautiful job in making our home complete."

"TNN managed our new construction and land development project from scratch. Tim caught MANY errors by the Engineer and Architect before they could become a problem. He made many great suggestions to elevate our original plans. Work quality is great and they take pride in everything they do. Nick did an amazing job on our trapezoid windows and carpentry work. We highly reccommed TNN and will continue to use them for the next phase of our project (garage) We would be happy to provide a reference and even show the work they completed for our project.
