Finding the right contractor in NYC can make or break your renovation project. In this exclusive interview, we sit down with Sarah M., a top Manhattan real estate agent, and Michael Ch., Project Manager at Hoppler Design and Build, to discuss the essential questions every homeowner should ask when interviewing contractors.

Sarah M.: Michael, I work with clients daily who are purchasing homes that need renovation work. As someone who’s managed dozens of projects in NYC, what’s the first thing homeowners should ask when interviewing contractors?

Michael Ch: That’s a great question, Sarah. The very first thing should be about licensing and insurance. In New York City, contractors must have specific licenses depending on the work they’re doing. Homeowners should ask: “Can you provide your license number and let me verify it with the Department of Buildings?” At Hoppler, we’re fully licensed for all types of residential construction, and we provide this information upfront.

Sarah M.: I’ve seen too many of my clients get burned by unlicensed contractors. What about insurance?

Michael Ch: Absolutely critical. Homeowners need to ask for certificates of both general liability and workers’ compensation insurance. The question should be: “Can you provide current certificates of insurance, and will you add me as an additional insured?” We carry comprehensive coverage because in NYC, anything can happen on a job site. Without proper insurance, the homeowner becomes liable for accidents or damages.

Sarah M.: Let’s talk about experience. What specific questions should homeowners ask about a contractor’s background?

Michael Ch: They should ask: “How long have you been working specifically in NYC, and can you show me examples of similar projects?” NYC construction is unique; we deal with co-op boards, landmark buildings, tight spaces, and specific building codes. A contractor who’s worked in the suburbs isn’t necessarily prepared for Manhattan’s challenges. We’ve been working exclusively in NYC for over eight years, and we can show photos and addresses of similar projects.

Sarah M.: References are huge. How should homeowners approach this?

Michael Ch: Smart homeowners ask: “Can you provide references from your three most recent projects, including contact information?” But here’s the key, they need to actually call those references. I always tell potential clients to ask previous customers about timeline adherence, cleanliness, communication, and how we handled any unexpected issues. We’re proud that over 90% of our clients would recommend us without hesitation.

Sarah M.: Project management is where I see many contractors fail. What questions reveal how organized a contractor really is?

Michael Ch: Great point. Homeowners should ask: “What project management system do you use, and how will I track progress?” At Hoppler, we use cloud-based project management software that gives clients real-time access to schedules, progress photos, and budget updates. We also ask: “Who will be my primary point of contact, and how often will we communicate?” Poor communication kills projects.

Sarah M.: Speaking of communication, what should homeowners know about a contractor’s communication style?

Michael Ch: They should ask: “What’s your preferred method of communication, and what’s your response time for questions?” Some contractors only communicate through foremen on-site, others prefer email, and some use project apps. We believe in multiple touchpoints, weekly progress calls, daily text updates when needed, and 24-hour response times for any concerns. Homeowners should feel comfortable with the communication style before signing anything.

Sarah M.: Let’s get into the financial questions. These can be uncomfortable but they’re essential.

Michael Ch: Absolutely. First question: “Can you provide a detailed, itemized estimate breaking down materials, labor, and other costs?” Avoid contractors who only give lump sum bids. Second: “What’s your payment schedule?” Red flag if they want large upfront payments. We typically ask for 10% to start, then progress payments tied to completion milestones. Never pay more than work completed.

Sarah M.: What about timelines? This is always a concern for my clients.

Michael Ch: Homeowners should ask: “What’s your realistic timeline, and what factors could cause delays?” Honest contractors discuss potential issues upfront. We provide detailed schedules showing each phase, and we build in buffer time for unexpected discoveries, which happen in 70% of NYC renovations. We also ask clients about their flexibility with timing.

Sarah M.: Permits and approvals, this is where NYC gets tricky.

Michael Ch: Exactly. The question is: “Who handles permits and DOB filings, and what’s included in your fee?” In NYC, many projects require Department of Buildings permits, and some need architect drawings. At Hoppler, we handle all permitting and have relationships with expeditors when needed. Contractors who aren’t familiar with NYC permitting will cause major delays.

Sarah M.: What about the actual work crew? Should homeowners ask about the people who’ll be in their homes?

Michael Ch: Definitely. Ask: “Will you be using employees or subcontractors, and are they all properly insured?” Also: “Can you provide background on key team members who’ll be working in my home?” We employ a core team of professionals who work together regularly. This ensures quality control and accountability that you don’t get with random subcontractors.

Sarah M.: Cleanup and protection, especially important in occupied homes.

Michael Ch: Homeowners should ask: “What’s your daily cleanup process, and how do you protect existing finishes?” In NYC apartments and occupied homes, dust containment and daily cleanup aren’t optional. We use plastic sheeting barriers, HEPA air scrubbers when needed, and leave work areas clean each day. This should be standard, not an upcharge.

Sarah M.: What about warranties and what happens after completion?

Michael Ch: Critical questions: “What warranty do you provide on your work, and how do you handle callbacks?” We provide a comprehensive one-year warranty on all workmanship and help coordinate manufacturer warranties on materials. We also maintain relationships with all our past clients for any future needs.

Sarah M.: Any red flags homeowners should watch for during interviews?

Michael Ch: Several major ones: contractors who won’t provide license numbers, demand large upfront payments, can’t provide local references, give verbal-only estimates, or pressure for immediate decisions. Also, be wary of door-to-door solicitors or extremely low bids; quality work costs appropriate money in NYC.

Sarah M.: Before we wrap up, what’s your advice for the actual interview process?

Michael Ch: Interview at least three contractors, and make sure they visit the site in person; never accept estimates based on photos. Prepare your questions in advance, and don’t be afraid to ask follow-ups. The right contractor will welcome detailed questions because they show you’re a serious, prepared client. At Hoppler, we actually prefer clients who ask tough questions.

Sarah M.: Any final thoughts for homeowners about to start this process?

Michael Ch: Remember, the lowest bid is rarely the best value. Focus on finding a contractor who demonstrates professionalism, transparency, and genuine expertise in NYC construction. A good contractor becomes your partner in creating your dream space. The interview process isn’t about interrogating contractors; it’s about finding the right fit for your project and communication style.
