[…] We are so excited to share that HG&Co. made all of our dreams come true and beyond with this project! Herman and his professional team did an absolutely amazing job building us our dream garage.[…]
Marzella was absolutely incredible to work with throughout the entire project. Her professionalism, attention to detail, honesty, and strong communication skills outshines anyone in the industry. Thank you so much Marzella!
We love our home sweet home even more than we did before with this new addition. We highly recommend HG&Co. for any renovations you may need! Thank you all again so much!
My husband and I used HG & CO to turn our detached garage into a livable space with a full bathroom. […] I found this company online and was immediately impressed with Herman.
His team did a very thorough job converting our garage. The work was very well done, and Herman’s team responded to our concerns and additional requests throughout the whole project. We plan on using them in the future for additional work.
Definitely check this team out for any remodeling needs! You’ll see HG & CO. signs everywhere which speaks highly of the company. They are in demand.
Thank you!

Herman built HG & Co around one priority: the client experience matters at every stage. Watch him explain how that shows up on a real home addition project, from the first design meeting to the final walkthrough.
