Egress Windows questions, answered by experts

An egress window is similar to a regular window. However, this type of window opens fully to allow people to escape the home or rescue personnel to enter the home if an emergency occurs. Egress windows are required in all finished basements before they can be considered a living space.

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• What experience do you have 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?

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.
