A load-bearing wall is a structural wall that supports the weight of the floors or roof above it. Unlike partition walls, removing or modifying a load-bearing wall requires engineering consultation and structural reinforcement. Identifying these walls before any remodel is critical to maintaining your home’s structural integrity.
The subfloor is the foundational layer of flooring installed directly over the floor joists, beneath your finished flooring material. It provides a stable, flat surface for tile, hardwood, or carpet installation. During a remodel, a damaged or uneven subfloor must be repaired or replaced to ensure the durability and appearance of your new flooring.
A permit is an official approval issued by your local government authorizing specific renovation or construction work on your property. Many remodeling projects — including structural changes, electrical work, and plumbing updates — legally require a permit before work begins. Unpermitted work can complicate home sales and pose safety risks.
Rough-in refers to the early stage of installation when plumbing, electrical, or HVAC systems are put in place behind walls before surfaces are finished. This phase establishes the framework for your home’s mechanical systems without any visible fixtures or outlets. Rough-in work must pass inspection before walls are closed up and finishing work begins.
