WHAT OUR CLIENTS SAY
Custom Home in The Kingsway
Building my custom modern home in The Kingsway was a milestone project, and Claudio was my first and only call. His craftsmanship is outstanding, every finish, line, and design detail reflects pride and skill. But beyond that, it’s his reliability and trustworthiness that truly separates him. He was there from blueprint to final walkthrough, treating the build like it was his own home. Claudio is a rare combination of builder, craftsman, and partner, someone you can trust completely to bring your vision to life and deliver excellence every time. Thanks again, Claudio, appreciate everything you and your team continue to deliver
Co-Branded Franchise – Second Cup & Noodle Box
Claudio and the team at Moderna Design Build are the definition of reliability and craftsmanship. Building two national franchises under one roof required precision, coordination, and creativity, and they delivered flawlessly. Claudio earned my complete trust throughout the process. When challenges surfaced, he was proactive, transparent, and focused on solutions. The final product wasn’t just on time; it was better than imagined. He’s the kind of builder who makes you feel confident the job will get done and done right.
Home Renovation
A major renovation project can easily become overwhelming, but not with Claudio. His team’s workmanship and dependability were second to none. Every step was communicated clearly, deadlines were met, and the quality of work was exceptional. What stood out most was Claudio’s integrity, if he says it will get done, it gets done. You can count on him not just as a contractor, but as someone who genuinely takes pride in the work and stands behind it.
Custom Home in Davisville
In 2020, we engaged Moderna to build a custom home in midtown Toronto. The project presented a number of unique challenges: pandemic-era supply chain disruptions, a narrow urban lot with limited parking, a major construction project underway next door, and a particularly difficult neighbouring property owner. Despite these complexities, Claudio navigated the build with professionalism, diplomacy, and skill. Claudio maintained strong working relationships with adjacent property owners and the neighbouring construction team, helping to minimize friction and keep the project on track. He managed pandemic-related timeline and budget pressures with transparency and flexibility, offering us clear options when adjustments were needed. He successfully incorporated all our must-have design features and provided thoughtful guidance on cost-effective alternatives for other elements. When supply chain issues led to cost increases in certain areas, Claudio proactively identified savings elsewhere to keep the overall budget in check. Claudio assembled and coordinated a talented team of professionals, including an architect, interior designers, and specialized contractors—most notably an expert in whole-home radiant heating. He held all trades to a high standard of workmanship, ensuring that any deficiencies were promptly addressed and that performance issues were resolved through his strong industry relationships. Throughout the build, Claudio remained accessible and responsive to any concerns from neighbours, which helped preserve positive relationships even after construction was complete. He ensured that all inspections were passed, permits were closed in a timely manner, and that supply chain delays did not jeopardize our occupancy timeline— ultimately helping us avoid unnecessary insurance costs.
After we moved in, Claudio continued to support us by addressing outstanding items on our punch list and providing warranty service as needed. He even initiated a one-year post-occupancy review to proactively address any settling-related issues.
We are thrilled with the final result and regularly receive compliments on our home, which is often cited as one of the most beautifully built on our street. Much of that credit belongs to Claudio and the thoughtful, high-quality work he delivered from start to finish.
A Trusted Builder and Partner
I’ve had the pleasure of working with Claudio on multiple projects, and he’s consistently been a reliable and collaborative builder. He’s always available to meet on-site to resolve any issues that arise, and his clear, open communication makes the design and construction process seamless. Claudio’s attention to detail and commitment to quality show in the finished product every time. He’s truly great to work with.
Cure Salon Spa
The Cure Salon Spa build was a demanding project, blending high-end design with technical complexity. Claudio’s craftsmanship, attention to detail, and reliability made all the difference. He approaches each space like it’s his own, ensuring quality from start to finish. His calm professionalism and commitment to partnership turned what could have been stressful into a seamless experience. Moderna Design Build is the kind of team you trust with your vision, and they deliver it beautifully.
