Expert Room Additions in Metro Phoenix & Maricopa County

Room additions give Chandler homeowners a direct way to add square footage without leaving the neighborhood they know. R&M Remodeling handles the full scope of a home addition, from initial planning and design through framing, mechanical rough-ins, insulation, and finish work. We build additions that match your existing roofline, exterior finish, and interior flow so the new space feels like it was always there. In Chandler, room additions require a full building permit and site plan submittal through the city's Development Services department. HOA covenants also apply in many established Chandler subdivisions, so we factor those requirements into the planning stage before any work begins. Whether you need a primary suite, a dedicated home office, a larger family room, or a flex space for a growing household, we design the addition around how you actually use your home. Call R&M Remodeling to talk through your project and get a clear picture of what your addition will take.

R&M Construction and Development did an excellent job painting the exterior of my home. From the beginning, they were transparent about the work that needed to be completed to ensure the best possible results. They were also very accommodating with last-minute changes and provided helpful recommendations throughout the decision-making process. The project was completed ahead of schedule, and I was able to see noticeable progress every day. Overall, I highly recommend R&M Construction and Development for any home improvement project.

Had the best experience with R&M Construction and Development. We redid all of the flooring, full interior paint and remodeled 2 bathrooms with them. The work they did came out amazing. They were very professional. We were not living at the home when the work was done but we went frequently to check on it and every time we went the home was always cleaned up by the time they left. Their team whole very helpful. They helped us with painting samples and explained the different paints. I'm in love with how everything turned out. I would highly recommend them.

R&M Construction and Development did an outstanding job building my spec home in Tonopah, Arizona. From start to finish, their team was professional, organized, and easy to work with. Communication was clear throughout the entire process, and they kept everything moving on schedule while maintaining high-quality workmanship. Their attention to detail really stood out from the finishes to the overall build quality, everything was done right the first time. They were transparent with costs, handled challenges quickly, and made the whole experience smooth and stress-free. If you’re looking for a reliable builder who takes pride in their work and delivers exactly what they promise, I highly recommend Ramiro. I’m excited to keep working with him on the second spec later this year. Jose Romero

I am very happy with the final result of my bathroom remodel by R&M Construction & Development. They have a great team! They communicated with me consistently through out the whole project, answered every question or concern I had immediately (day or night), explained everything in great detail, and reassured me regularly. I trust them completely and will use them when I have another project. I highly recommend them to friends & family,

Janet Johnson Google review · June 2026

I remodeled my whole home with R&M and his team. From floors, paint, kitchen, bathrooms, underground plumbing, patio and a few other projects and I cant say enough about them. The team is very competent! They communicate with you throughout the whole project and the quality is top notch. If you’re looking for quality and a great experience overall, this is your contractor.
