"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

"The portico design itself was a challenge, made more so by our choice of materials and the need for John to work with the Historic Commission. Perfect man for the job, lots of time in the design process, a true craftsman in execution - perfect results and a show-stopper. Passersby stopping to take photos!"

Egress Windows questions, answered by experts

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.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

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.

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.

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.
