Stop your Google search here because this will be your go to business. I have a couple projects going on and got referred to Infinity Construction Group, After a phone call I got to meet Walder and he overlooked my Asphalt and Metal Roofing Job. The Price was great and the work and experience was FIVE STAR. I'm very please and will continue to use them in the future for all my roofing needs.
I hired Walder for many projects and they did a great job! Highly recommend!
I would like to share that infinity group was the best choice for my project. Walder was amazing helping me to choose the best material and about the work done it is awesome more than expected and me and my wife are more than happy with it. Thank you infinity construction.
I will never recommend this company in the future. Junior painted my house about 2 years ago and I have paperwork that guarantees the job for 10 years.. First they did not follow the contract, wrong primer, paint bubbles throughout the outside of house and no follow up after constant calls. Worse experience in my life.
Walder and his team did a fantastic job painting our kitchen cabinets. High quality work at a reasonable price. They are a professional and diligent group, and we would love to hire them in the future.
