“So to start off I must say that my husband and I are very detailed oriented and have had some terrible experiences in the past. Due to those experiences we spend tons of time researching companies and what they have to offer before spending our hard-earned money on a product or service. JM buildings have exceeded our expectations. Many times once a sale is made you don’t hear from companies again. However, JM Buildings provided excellent customer service and remained in constant communication with us regarding our carport purchase and installation answering all of our questions. I highly recommend JM Buildings! We love our boat carport!”

 Trustindex verifies that the original source of the review is Google. We recently purchased a 40×18×14 RV cover. Fred made the process easy with the design and engineering. The work crew was great.  The materials are solid and poles are extra "Heavy" duty. I had cross beam brackets added and the welds are done very nice. Great job and I would definitely use again.

 Trustindex verifies that the original source of the review is Google. JM Metal Buildings & Construction made the process of designing and constructing my metal building (10'x20'x8') extremely simple and were extremely helpful and available. As a developer, I am glad to have found an honest and knowledgeable vendor I can trust, and I look forward to my next project with them on a larger scale.

 Trustindex verifies that the original source of the review is Google. We are very happy with our 24 X 30 metal RV cover.  The order arrived and there were no surprises, everything was as ordered.  The installers were great to work with and spent about 7 hours getting it fully installed. I'm really glad we decided to order the back part with the double gable, and the front gable looks great and matches our house colors nicely.
Violet Durant is our customer service rep and she was very knowledgeable and helped us through the designing and ordering process.  Thanks Violet.
We would order again from JM Buildings.

They walked me through the process of customizing my specific builds and requirements. They are very easy to work with, offer a variety of flexible financing options and have a great installation company that completed the project quickly and cleanly. I highly recommend JM buildings.
