"Mike was able to fit me in the same day for an estimate which surprised me because I'm sure a lot of people are needing his services with all the rain lately but he was in the area that day and came by. Although the company is a nation wide chain, its a franchise and a small business. He is an honest Vermonter with Vermont values which I appreciate. He gave me options but didn't try to talk me into something I couldn't afford and is doing the work within two weeks which I was also happy about being a very busy time for this type of thing."

Egress Windows questions, 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.

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.

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.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

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.
