"Great. Had my basement finished. They put in a bathroom and finished rest of basement into a craft room. Love the way it turned out. I'm having them turning a small room into a pantry. I had to ask them for extra time before they start the pantry. My mother isn't well and i needed to take care of some things before i was ready to start on that. They were good at working with me. Would recomend them to anyone who needs work done."

"Bob and his colleague were detail-oriented, thorough and professional throughout the time they were in my home. They were cognizant of another obligation I had later that day and worked efficiently, but accurately to get the job done and done right. I would highly recommend Robert Horne Contracting!"

"Everything was above board. From the quality of their work and their product, to their outstanding customer service. Looking forward to working with them again."

"Carlito and crew did an excellent job. He seemed to make very sound suggestions about exactly what structural improvements were needed to the porch, and what was good to leave as it was. New screen and stain looks great. Crew was nice and picked up well. Katheryn in the office was also super helpful. Excellent company."

"Very well. The guys were very nice and worked hard. They cleaned up what we requested and hauled it away. The area around our shed now looks good. Would definitely hire them again."

"It was excellent. Mike was very informative and thorough. Prices were reasonable. They were on time to every meeting time. The best part was how willing they were to work with me with a timeline. They completed the tasks very proficiently."

"He gave us a great deal, and we scheduled the roof work and within 4 days his crew was scheduled. On the day of the roofing job, they were professional, and they finished the job in 1 day."
