Lead time is the elapsed time between ordering a material and receiving it. Semi-custom cabinetry: 8–14 weeks. Custom cabinetry: 12–18 weeks. Imported specialty tile: 6–12 weeks. Custom millwork: 4–8 weeks. Specialty lighting: 4–10 weeks. Long-lead materials not ordered at contract execution will routinely arrive late — holding the installation phase that depends on them, extending the project schedule, and creating storage costs for partially complete work waiting for the missing material. RainFire Builders identifies all long-lead materials at project initiation and orders them at contract execution — before construction begins — so materials arrive when installation is ready. This is not a luxury; it is basic project management that prevents the most common cause of residential construction schedule overrun.
