Materials run $25 to $1,500 across 7 projects. Dryer vent cleaning is the floor at $25 to $75, and ceiling fan installation sits at $150 to $400. The ceiling is outdoor lighting at $300 to $1,500, then duct and vent installation or removal at $300 to $1,200 and thermostat installation or repair at $150 to $850. Fixtures, fittings, and ductwork, materials only.
Where the DIY line sits
Five of the 7 projects rate Intermediate and 2 rate Beginner: dryer vent cleaning and window air conditioner installation. Nothing here is Advanced, and that is partly because of what we leave out. NailIt prices fixtures and fittings, not service work. We decline electrical panels and gas lines outright. Swapping a ceiling fan on an existing box with the breaker off is a fixture job. Adding a circuit, upsizing a panel, moving a service, or touching a gas line is licensed electrician and licensed plumber work, every time.
What moves the price
Fixture count and fixture quality do most of the work. Outdoor lighting scales with the number of heads, run length, and whether you are using line voltage or low voltage with a transformer. Duct and vent work scales with linear feet, duct type, and how many turns and boots the run needs. Thermostats split cleanly between simple programmable units and smart models that need a common wire. Access is the hidden driver: attic and crawl space runs cost more in fittings.
Frequently asked questions
Does NailIt estimate electrical panel or rewiring work?
No. We decline electrical panels, service upgrades, and gas lines, and we do not price them at any level. This category covers fixtures and fittings: ceiling fans, outdoor lighting, thermostats, ducts, vents, and window air conditioners. If your project involves a panel, a new circuit, or a gas connection, get a licensed electrician or plumber. That is a permit and inspection job, not a DIY estimate.
How much does it cost to install outdoor lighting myself?
Outdoor lighting is the top of this category at $300 to $1,500 in materials. That covers fixtures, cable, a transformer for low-voltage runs, stakes, and connectors. Head count and run length drive it. Low-voltage landscape lighting is the DIY-friendly path because it does not require opening a panel. Anything that needs a new circuit is outside what we estimate.
Is replacing a ceiling fan or thermostat worth doing myself?
Both are Intermediate and both are cheap in materials: ceiling fan installation at $150 to $400 and thermostat installation or repair at $150 to $850. A fan on an existing fan-rated box and a thermostat on existing low-voltage wiring are straightforward with the breaker off. If the box is not fan-rated, or the thermostat needs a common wire you do not have, the job grows.
