Many homebuyers purchase properties expecting to make improvements over the years. Those who choose fixer-uppers often plan larger projects than simply swapping laminate for hardwood or repairing a roof. No matter the scale of the remodel, knowing common construction terms helps homeowners communicate clearly with contractors and enables do-it-yourselfers (DIY) to complete projects that meet code.
Below are 10 frequently used terms you’ll encounter during a remodel.
1. Flashing
Flashing is a material—typically sheet metal—used to prevent water intrusion at joints where different building elements meet, such as where a roof meets a chimney or dormer. Proper flashing is essential to avoid water damage and leaks.
2. Easement
An easement is a legal agreement granting the right to use someone else’s land for a specific purpose. Common examples include a sewer line crossing a neighbor’s yard or a shared driveway that allows access to properties behind a public street.
3. Egress
Egress means a way out. Building codes require safe egress routes from each level of a home, ensuring occupants can exit quickly in an emergency. Proper placement and sizing of windows and doors are part of egress compliance.
4. Joists
Joists are long structural members—usually wood or engineered lumber—set parallel in a series to support floors, ceilings, and roofs. Floor joists provide the framing beneath flooring materials and are spaced 12 to 24 inches apart. They span between perpendicular beams, which transfer loads to load-bearing walls and ultimately to the foundation.
5. Load-Bearing Walls
Load-bearing walls support structural weight from the roof and upper floors. Exterior walls are almost always load-bearing, and many interior walls near the center of the house also carry loads. The original building plans will identify which walls bear weight. Removing or altering load-bearing walls should be handled by qualified professionals to preserve the home’s structural integrity; non-load-bearing partition walls can be removed more safely by DIYers.
6. Molding
Molding refers to the decorative wood trim that finishes transitions between surfaces. Crown molding sits where wall meets ceiling; base molding, or baseboard, runs along the joint of wall and floor. Molding adds visual detail, defines room proportions, and gives a finished look to interior spaces.
7. Setback
Setback is the required distance between a structure and property boundaries, streets, waterways, or other regulated features. Local zoning and building codes set setbacks to protect views, maintain neighborhood character, and reduce flood risk. Setback rules can limit where additions, fences, and landscaping may be placed.
8. Stair Rise
Stair rise is the vertical height between the surfaces of consecutive steps (treads). Building codes set maximum limits for stair rise to ensure safety and comfort; a common limit is about 7.5 inches, though local codes may vary.
9. Sub
“Sub” is short for subcontractor—a tradesperson or specialty contractor hired to perform a specific portion of work. The general contractor manages the overall project, contracts directly with the homeowner, and hires subs for tasks like plumbing, electrical, or roofing.
10. Tongue and Groove (T&G)
Tongue and groove describes a method of joining wood boards so their edges interlock. One board has a projecting “tongue” while the adjacent board has a matching “groove.” When fitted together, the joint creates a flat, secure surface commonly used for flooring, paneling, and ceilings.
These ten terms will make conversations with salespeople, contractors, or friends helping with a weekend project clearer and more productive, helping you plan and execute remodels more confidently.
