"Kris was amazing to work with. He is a true craftsman with many skills to tackle any job. I would highly recommend him."

"We added a full bathroom in our garage and an additional 16 ft wall with an interior door. The project went well and we’re very happy with the work that was completed. Bob is an amazing person to work with as is his wife Laura. They made the process easy from planning & permitting, to choosing the right materials and layout. Everything went as expected. Bob went above and beyond to insure the job was completed on time as we had a specific timeframe that we needed the job to be completed. We would hire Bob again for another project in the future. Thanks so much Bob!"

"We had Home Remodeling Pros build a composite deck on our new home. We absolutely LOVE our new deck! Working with Craig and his team was a pleasure. They were very professional and did an amazing job. We would recommend them for any remodeling job. Thank you Home Pros!"

"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."

"Would have liked landing and steps a few inches wider I can’t change my storm door now. But I didn’t see that until done. Nice solid steps. Much easier entry. Thank you. Merry Christmas. Peace."

"Nate and Junior did a wonderful job and charged a fair price.. They installed three sheets of drywall and repaired existing drywall in a small powder room. The work was performed quickly with virtually no dust or extra joint compound created when finishing the joints. It took awhile to get the work scheduled mostly due to Covid-19 but it was well work the wait. I would recommend this firm for drywall installation/repair."

"Yaniel's Renovation LLC completed remodeling work, including putting in hardwood floors, installing cabinets, vanities, and doors, and interior painting. Francisco and his team worked to ensure that the home improvements were to my liking and that they were suitable down to the very last detail. They remodeled with an eye towards the future maintenance of my home. Rosa was immensely responsive. I am very pleased with the results."

"Dean and his team were very professional. They were able to come in and quickly give me an estimate and schedule the job. The job was done in a timely fashion and they gave me updates all the way. They cleaned up well and I didn't have to worry about drywall dust and materials left behind. Even stayed late to make sure the job was completed on the date promised. I will be using them again for a bathroom addition in the future. They did an amazing job and the bathroom turned out beautifully!"

"Lee Dickerson installed a new addition to our 12 yr. old home. It is a sunroom, but also an extension of our family room. We were very pleased with the work performed by Lee Dickerson & Sons. The job went smoothly from our first meeting to completion. Lee Dickerson has tons of experience in his field and was especially helpful with ideas that we hadn't thought of. His crew did an amazing job of keeping the job site clean each day. We were completely satisfied with this company and I would highly recommend them."
