Trade terms guides
Guides: Trade terms.
- AFCI vs GFCI: two different protections
AFCI addresses dangerous arcing and GFCI addresses ground-fault shock hazards. Confirm the required protection for each circuit with the electrician.
- Blower door test: what builders need to know
Plan enclosure testing early enough to locate and repair leaks, then keep the final result with the house and HVAC documentation.
- Coped vs mitered inside corners
For profiled interior trim, coping accommodates an imperfect inside corner. Choose the joint with the material, finish, and approved sample in view.
- Countertop templating: what has to be ready
Book the template when the installed cabinet layout and required fixtures are ready. Put a decision-maker on site and control every change afterward.
- Drywall finish levels: what Level 5 means
Specify the finish level with the final paint and lighting, then approve a representative sample before the crew finishes the whole house.
- Kick-out flashing: small part, big callback
Kick-out flashing sends roof runoff away from the wall. Assign the roofer, WRB installer, and siding crew before anyone closes the junction.
- Manual J: why HVAC sizing starts on paper
Request a load calculation for the actual house, then coordinate equipment selection and duct design before the HVAC package is ordered.
- PEX vs CPVC for water lines
Choose a complete water-piping system with the plumber, then specify its connections, installation instructions, and inspection requirements.
- RESNET insulation grades I, II, and III
RESNET grades describe installation quality. Agree the required standard and inspection visit before covering the insulation.
- Structured wiring and low-voltage pre-wire
Structured wiring needs a room-by-room plan, labeled cable runs, and an agreed test standard. Separate installed wiring from internet activation.
- Water-resistive barrier behind siding
A water-resistive barrier manages rain that gets behind siding. Check the complete drainage path, including openings and penetrations, before covering it.
- Window sill pans and flashing order
A sill pan collects water at the bottom of a window opening and routes it outside. The window, pan, flashing, and wall barrier need one compatible detail.
