Vacuum Kiln Drying
Shop Overview · Vacuum Kiln Drying
At John's Urban Timber, we use advanced vacuum kiln drying to bring reclaimed and salvaged wood to perfect moisture balance while preserving its natural character. Unlike conventional kilns, our vacuum process gently removes moisture at lower temperatures — reducing stress, cracking, and discoloration.
All Drying Done In-House — Never Outsourced
Every board and slab is processed on-site at our Whitmore Lake workshop. We don't send materials elsewhere, ensuring complete control from start to finish.
Built for thick slabs
Our vacuum kiln accommodates a variety of species and thicknesses, making it ideal for live-edge slabs, custom lumber, and reclaimed materials. Drying times vary based on thickness and species, but most projects reach optimal moisture content in just a few days to weeks — compared to months in traditional systems. We take pride in giving every piece the attention it deserves, so you receive beautifully conditioned wood that's ready to use right away.
