"Excellent job on the window tinting project. The quality of the work is top- notch, clean precise and professionally done. The tint not only enhanced the look of the home but has reduced the glare and heat, just as I had hoped. Cassandra was respectful of our space and left everything spotless after the job was done. I’d highly recommend to anyone looking to upgrade their home Windows. Outstanding work with a fun personality!!"

Windows questions, answered by experts

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Installing energy-efficient windows costs between $325 and $2,000, averaging about $400 per window. You’ll have to consider cost factors like the window’s size, frame material, and type. Labor costs in your area will also impact the overall cost of the project, with window installation professionals charging about $40 per hour on average. Different types of energy-efficient windows include:

  • Single-hung: $150–$2,500

  • Casement: $150–$600

  • Double-hung: $250–$3,000

  • Picture: $200–$650

  • Bay: $480–$1,920
