A 2025 customer on Houzz described their "treehouse" project with Charlie, from the groundwork and framing through to the fine trim work and screen installation, and said he created an invisible door to access underneath the deck. CMT Builders' Houzz profile names Charlie Thieme as the company's owner and carpenter and says he has been in the trade since 2008. That 2025 customer said the permit process with their town was smooth because he was familiar with the building codes, with thumbs up at all inspections. The same 2025 customer said he was patient with their material selections. A 2025 Houzz reviewer said Charlie kept in touch and communicated well, and said they would call him for their next project.

We love our “treehouse” and would hire CMT Builders for any of our future projects. Charlie is a skilled craftsman with proven attention to detail from the groundwork, to framing, all the way through to the fine trim work and screen installation. He even created an invisible door to access underneath the deck. The permit process was smooth with our town since he was familiar with the building codes, receiving thumbs up at all inspections from an enforcement officer known for being by the book. He was patient with our material selections, educating us every step of the way to ensure we were selecting a product that met our expectations. The end product was exactly what we envisioned and will most certainly last as long as our house is still standing.
