I purchased a 30 x 40 x 12 foot wall steel McGuires building in 2018. The purchase included code approval, tree removal, site preparation, concrete and erecting the building. The purchase included insulation and alternative doors and windows. I highly recommend the insulation as I am able to cool the building with a 22,000 BTU window air conditioner. The site manager, the foreman, and the workers were professional and attentive. Any calls or texts were promptly returned. The only delays were due to weather. I highly recommend McGuires for any building needs.
