Jim Smith was very competent and very expedient in giving us our quote for redesigning our dining room into a family room with french doors. His staff were wonderful, working with each other very well and checking with us when questions arose. Always on time. Cleaned up every day and put materials away safely. We requested that they paint the room on the second day of work. No problem. Done well. We will contact Jim for any future renovations. Recommend his work highly. Good quality. Done right the first time! Barbara and Michael Barry
I hired this general contractor for a home renovation project, and the results exceeded my expectations. They were highly organized, communicated clearly throughout the entire process, and completed the work on time. The team paid close attention to detail and ensured that everything was done to a high standard. I also appreciated their transparency when it came to budgeting and materials—there were no hidden surprises. The final outcome looks fantastic, and I’ve already received compliments from friends and family. I would confidently recommend this contractor for any construction or renovation needs.
Last Fall, Crossroads finished our basement, over 1800 sq feet, which was the culmination of a year’s worth of preparation, design and construction. Overall, they did an amazing job through every phase of this project, and we are very pleased and excited about our new finished basement space! Their attention to detail and willingness to share their ideas with us during the design and construction phases really made an enormous impact. The on site carpenters, Wayne and Kim routinely walked us through not only the work that they were doing, but also what other plumbing, electrical or HVAC work was also planned on any given day.. In addition, we really liked their mobile app as it allowed frequent and easy communications when we had any questions. The app also gave us terrific transparency into the working schedule, so that we knew who would be at our house and what they would be doing at any time. We highly recommend Crossroads for their quality craftsmanship, attention to detail and ease of communications throughout a project.
We hired Crossroad Contracting to remodel our home in the summer of 2024, and the experience was nothing short of perfection. From our very first meeting with Josh, we knew we were in good hands. He listened closely to our needs, offered insightful advice, and set clear expectations so that there were never any surprises. His guidance even helped us finalize our blueprint. Shortly afterward, we were introduced to Darren and Bob—both of whom made themselves immediately accessible. Darren kept us updated with a detailed weekly email, while Bob expertly managed the day-to-day operations on site. They were respectful of our home, our family, and our busy schedule, ensuring that every detail was handled with care. The crew’s talent was evident in the remarkable “facelift” our home received. Even when last-minute changes were necessary, their flexibility and responsiveness shone through. Their exceptional follow-up made us feel like a top priority, taking the stress of coordinating multiple trades—painters, hardwood installers, and window technicians—completely off our shoulders. We know we are missing many names but we thank you all! A few months after the project had finished, we encountered a minor plumbing issue. Their follow-up and guarantee were as impeccable as their work; they prioritized the matter and fixed the issue immediately. We highly recommend Crossroad Contracting and look forward to working with them on our next project! Moe and Giuliana
Picking Crossroads Contracting to do our large renovation was the best decision we ever made. They were extremely professional, and an immense pleasure to work with. Their whole team is outstanding. The craftsmanship cannot be beat. Keri Davidson's home designs truly continue to bring us so much joy. We want to thank them for caring for our home like it was their own. We will be using them for another renovation in the near future!
I can’t say enough great things about working with Keri. She truly goes above and beyond—not only for her own clients, but also for mine. She did a wonderful job helping my client who relocated to New Hampshire renovate his townhome, designing a fantastic open-concept kitchen that perfectly fits his needs, lifestyle, and personal taste. The final result is absolutely stunning. Her attention to detail, creativity, and ability to truly listen make the entire process seamless. From layout and functionality to finishes and design choices, she brings everything together in a way that feels both beautiful and intentional. I confidently recommend her to anyone looking for a designer who is talented, thoughtful, and a true professional. Five stars without hesitation!
