"Exact exteriors did an amazing job. It took a little bit to get the windows from the manufacturer but once the materials were here the job was completed fast. The workmanship was very high quality. I was comfortable with all the workmen who installed new window new siding, new gutters and did a little bit of exterior painting. The house was very tired looking and now looks amazing. I was very happy with this company. I found them to be of high integrity and would hire them again."

Egress Windows FAQs, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

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?

There are a range of egress window types available, including:

  • Single-hung: $100–$400

  • Double-hung: $250–$500

  • Horizontal/sliding: $150–$800

  • Casement: $200–$500

  • In-swing: $350–$700

When choosing a type of egress window, consider how you’d like to open it. For example, double-hung egress windows open from top to bottom and let plenty of fresh air in, whereas sliding windows slide open for easy access.  

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.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.
