“We recently had a 25×40 garage installed on our property, and we couldn’t be happier with the entire experience.
From the very beginning, our sales representative, Jonathan, was incredibly helpful, knowledgeable, and responsive. He always kept our minds at ease throughout the process and was available to answer any questions we had along the way.
The crew that came out from Custom Built Structures to build the structure was equally impressive. We were told the lead time would be 8-12 weeks and they came out in just 2 weeks. They were professional, fast, and efficient, and it was clear they took pride in their work. They kept the job site clean and made sure to clean up after themselves, which we greatly appreciated.
The finished garage looks absolutely amazing and exceeded our expectations. We highly recommend American Metal Buildings to anyone looking for a quality custom-built structure and outstanding customer service from start to finish.”
- Plan the concrete surface around the final layout:
Door placement, window locations, and building dimensions should be confirmed before the slab or install area is finalized. - Think through roll-up door access early:
Karlie’s garage includes two 10’ x 10’ roll-up doors on the right side, which can work well when you need wider access for vehicles, storage, or equipment. - Add windows where they actually help:
The two 30” x 30” windows add natural light without overcomplicating the design. Window placement should support how the space will be used inside. - Compare the full build, not just the size:
Roof style, framing gauge, certified rating, doors, windows, and install surface all affect the final building experience. - Ask questions before the order is finalized:
Karlie’s review specifically mentions how helpful clear communication was throughout the process, especially while decisions were being made. - Keep timeline expectations flexible:
Lead times can vary by location, manufacturer schedule, weather, site readiness, and project details. Karlie’s review reflects her specific experience.
Yes. A 24×40 garage gives 960 sq ft of usable space, making it practical for parking, storage, workshop use, or mixed-purpose needs.
A vertical roof refers to the roof panel direction and roof style. It is commonly chosen for better water and debris runoff compared to some other roof styles.
It means this building configuration was certified for a 145 MPH wind rating and 30 PSF snow load based on the ordered specs.
Two roll-up doors can improve access when the building is used for vehicles, equipment, or separated work/storage zones.
Concrete is a common installation surface because it provides a stable base and makes the interior easier to use for parking, storage, and workshop activities.
