"They did an excellent job. They were expensive, but you get what you pay for. The building inspector of the city said this was the best built garage he had ever inspected. I would highly recommend them and I would definitely hire them again."

"Jim and his team were great to work with. I needed a garage and a driveway but I was on a tight budget and had never done a construction project like this before. Garage Elements did a fantastic job helping me understand the options, what each item would cost so I could pick and choose what I wanted while staying on budget. Really appreciated the great communication throughout the project and Garage Elements commitment to insuring I was happy with the final product. Would highly recommend them!"

"Used Angie to find a local (handyman) and within minutes was contacted by Tim. He arrived at my house within hours and was able to find the issue with a light fixture, that I could not resolve. Very satisfied with the work and Tim was great to work with. Will be recommending him to any neighbors that need help."
