"Professional, timely and experts at home comfort remediations. Ben was a pleasure to work with and quickly became a trusted advisor. The install was under a pork and deck and they did a superb job. The porch is so much more comfortable on these 46 degree mornings. Highly recommend them - you will thank yourself every morning"

"John Ast was amazing to work with. He spent a lot of time researching options for us. He would come back with detailed notes and pricing. It was a big decision for us to replace our entire house exterior with Hardy Board late last year(2017). John's crew was amazing - very thorough. There were just one or two surprises that impacted the overall budget. It has been months and not an issue. Top quality work!"

"JDS is a fantastic company and a pleasure to work with. Jordan, the owner, came to my house to evaluate the job and provide an estimate. He was very detailed and honest in his assessment. He made various recommendations that substantially improved the setup of the systems, including some that helped reduce costs. A few days before the job was to start, I had to re-schedule due to unrelated reasons. Jordan was able to reshuffle his schedule to be able to accommodate my new timeframe. His crew was always punctual, clean, and respectful of my house. They worked very efficiently and were able to complete the job in under a week. The two windows look great and have substantially improved the feeling of the basement, I would highly recommend JDS to anyone looking into egress windows. Outstanding experience!"

Egress Windows questions, answered by experts

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.

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.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

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.
