How to hire a window installer
- Compare U-factor and energy ratings. Look for ENERGY STAR ratings for northern climates.
- Ask about installation method. Confirm flashing, insulation and trim details.
- Check lead-safe practices. Pre-1978 homes need EPA RRP certified contractors.
- Understand warranties. Separate manufacturer and installation warranties.
- Avoid pressure sales. Get multiple quotes before signing.
Red flags to watch for
- "Today only" pricing
- No mention of flashing or insulation
- Will not specify brand or model
- Large deposit before measurement
Licensing in Minnesota
Window installers need state contractor registration where required; firms working on pre-1978 homes need EPA lead-safe certification.
The Minnesota Department of Labor and Industry licenses residential building contractors, remodelers and roofers. Electricians and plumbers hold separate state licenses, and radon professionals must be licensed by the Minnesota Department of Health.
Best time to hire
Spring and fall are ideal; winter installs are possible and often easier to schedule.
