"Great experience getting windows installed by American Home Renewal. First contact was 6 months ago. I slept on it for a few months and got some other quotes. Chris was friendly as a sales man, Gave me a competitive price and some pointers on fiberglass vs vinyl. I went with Vinyl. Alex was the installer and was very detailed in explaining the install process. He explained everything in detail to me and showed me tips on how to do a proper install. We did a mix of new construction and retrofit. we added window casings and he was very thorough and asked multiple questions on how I wanted the casings to look. only hiccup was one of the windows was ordered wrong. we couldn't determine where the mixup occurred but they immediately took full ownership and reordered me a new window to the specs I wanted. I would highly recommend."

"The sales person, Sam was very through in his presentation and very detailed.. They were able to work with me on a date and showed up as scheduled . The installers were communicative and very neat. They even finished earlier in the day by bringing more help in as I had an unexpected appointment arise. I was shown pictures of the pre and post insulation to verify what was done. I would recommend them !"

"Dimitri provided siding replacement that was 30 yr old T111 that was warped due to sun exposure. He recommended hardey board for durability. The pictures I enclosed show tear off to finished install. Dimitri was very conscious about doing a good job and cleaned up after. I recommend using Dimitri if you need any exterior work."

"New Gen Exteriors removed the old vynl siding on my house and then installed new Hardie board siding with foam insulation underneath. Serg the owner was very polite, straight forward and easy to deal with, as were his men. They cleaned up each night and were also quiet when they worked, no loud radios etc. I plan on using Serg in the near future, because he does very professional work."

Eifs Installers FAQs, answered by experts

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.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

Installing a window well costs anywhere from $500 to $1,500 or more. Adding an egress window and well runs about $3,900 on average. Adding a window well cover to the project can add $200 to $700. A well cover helps protect your egress windows from weather damage and keeps them clear of dirt, debris, and wildlife.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

The average cost to install an egress window is approximately $3,900, with a typical range between $2,500 and $5,300, though costs can be higher. The final price is influenced by several factors, including the window's size, type, material, and glass quality. Other variables include labor costs, location, excavation needs, and whether permits or a structural engineer consultation are required. The price of the window itself often depends on the number of panes:

  • Single-pane: $100–$400

  • Double-pane: $200–$500

  • Triple-pane: $300–$800

Additional features like window wells or covers will also increase the total project cost. It is advisable to obtain multiple quotes from professionals to get a comprehensive understanding of the expenses for your specific project.
