Window Replacement Las Vegas: $450 to $1,200 Each + Permits

Las Vegas rows are local figures from ConsumerAffairs; the national row is labeled.

Do you need a permit to replace windows in Las Vegas?

Plan on one. ConsumerAffairs (September 2026) says window replacement in Las Vegas generally requires a building permit, with plans or extra review depending on scope. Windows are not on the City of Las Vegas list of no-plan permits it issues online, which covers jobs like exact HVAC change-outs, same-for-same water heaters, residential re-roofs and stucco, and the City says any other work would require a plan to be submitted and reviewed. If your home is in unincorporated Clark County rather than the city, the county issues the permit, so confirm which one covers your address before you sign.

78 days over 100 F: why glass ratings matter in Las Vegas

Las Vegas averages 78.2 days a year at or above 100 F, with a July normal high of 104.5 F, in NOAA's 1991 to 2020 normals at the airport, and only 9.8 nights at or below freezing. That makes the solar heat gain coefficient on the NFRC label as important as the U-factor, especially on west and south walls. ConsumerAffairs says Las Vegas has adopted energy-code rules that regulate window performance and tells buyers to ask for the NFRC label. ENERGY STAR says certified windows lower energy bills by an average of up to 13% when they replace single-pane windows. National frame prices: window replacement cost.

Newer homes, fewer lead worries in Las Vegas

The median Las Vegas home was built in 1994, the newest housing stock of the cities we cover for windows, so most houses here fall after the federal lead rule's 1978 cutoff. For an older house, the rule still applies: The EPA's Renovation, Repair and Painting rule says anyone paid to disturb paint in a home built before 1978 must be lead-safe certified, and the rule's minor repair exemption does not cover window replacement. The EPA estimates that about three-quarters of U.S. homes built before 1978 still contain some lead-based paint.

Nevada license: the C-14e doors and windows classification

Nevada licenses window work by classification: subclassification C-14e covers the installation and repair of doors, door frames, windows and window frames made of metal or wood. ConsumerAffairs says installers need an active Nevada State Contractors Board license in the proper classification, within its monetary limit, plus a City of Las Vegas business license before the City will issue a permit. Look the license up with the Contractors Board, and ask for proof of insurance, since the license record does not show it. Calls go to an independent company that serves your area and takes this kind of job (how calls work).

1. Do you hold a Nevada C-14e or other classification that covers windows, and what is your monetary limit?
2. Will you pull the City or Clark County permit, and is the fee in the price?
3. What are the U-factor and solar heat gain numbers on each NFRC label?
4. How will you patch and seal the stucco around each opening?
5. Can I see proof of insurance and a written price per window?
