EXCELLENT Based on 131 reviews Posted on Denice HoendorfTrustindex verifies that the original source of the review is Google. Builders Group Construction did an excellent job on our commercial remodel in Springfield, OH. This was for the front offices, the back of staff break room area as well as some of the executive offices of our Italian leather retail space, and the project covered about 4,000 sq ft. They handled flooring, lighting, painting, design guidance, cabinets, countertops, and wall accents. The crew was professional and respectful, worked fast, and kept disruption to a minimum so we could stay focused on business. The quality of the finished work is great and the space looks clean, modern, and built to last. Highly recommend them if you need a reliable commercial contractor in Springfield Ohio.Posted on Sharon and Lew BonadiesTrustindex verifies that the original source of the review is Google. I hired Builders Group Construction for an outdoor project in Yellow Springs, OH and I'm really happy with the results. They helped me improve the layout of my covered porch and made the space way more functional by installing removable porch screens all the way around. Before, I had one large screen across the whole porch and it was a pain to maintain, so the new setup is a huge upgrade. They also built a privacy deck around my grill area and installed a cedar porch gazebo that looks fantastic. Daniel's workmanship was excellent, and Jake stayed involved to make sure everything was completed the right way. The team was respectful, worked efficiently, and wrapped the project in about a week. If you need a screened porch or outdoor upgrade, I'd definitely recommend Builders Group Construction.Posted on Ed CoxTrustindex verifies that the original source of the review is Google. I hired Builders Group Construction for a remodel in Dayton and couldn’t be happier. They helped me design remodel a bathroom, installed new flooring, and handle several smaller updates that made the space feel finished and usable in the basement area. The process was organized My project coordinator helped me pick out my materials and the job site stayed clean considering the nature of the work. They delivered great craftsmanship with proper attention to detail. Thank you Kevin! They were responsive, explained options clearly, handled changes along the way well and we always knew what was happening next with the online schedule. Highly recommend them if you need a bathroom or flooring remodel in Dayton, Ohio.Posted on keith coltonTrustindex verifies that the original source of the review is Google. We hired Builders Group Construction for a kitchen remodel in Mason, Ohio and we love how it turned out. They helped us update the look and improve the layout so the kitchen works a lot better day to day. The finishes are exactly what we wanted-white marbled quartz countertops, a mosaic backsplash, a black craftsman-style cabinet island, and white craftsman-style perimeter cabinets. They also replaced our old carpet In the living and dining rooms with new hardwood floors, which made the whole space feel brand new without losing the character of the house. Great workmanship and solid communication throughout. If you're looking for a kitchen remodeling contractor. I'd recommend BGC!Posted on Christina kiklyTrustindex verifies that the original source of the review is Google. We hired Builders Group Construction for a multi-bathroom remodel in Springboro, Ohio (master bath, guest bath, and laundry room), and they absolutely delivered. This project required a ton of detail—intricate tile repair, fixing a garden tub, reinstalling an open corner shower, and finishing out the guest bathroom—and the workmanship was top-notch. What really stood out was the communication and organization. We had prior contractor documentation that fell short, and BGC took the time to sort through everything, document the issues properly, and keep the project moving with clear updates and a solid plan. If you’re looking for a reliable bathroom remodeling contractor in Springboro, Ohio (and the greater Dayton area) who can handle complex bathroom renovations, tile work, and shower/tub repairs with professionalism, I highly recommend Builders Group Construction.Posted on Teresa SchwabTrustindex verifies that the original source of the review is Google.
