"I was very pleased with my finished products I had waited a very long time to have a bathroom installed on the first floor. The problem was that I had very little space where it could be placed. I worked with Jake from West Penn who designed a perfect small bathroom for me when others said it couldn't be done......and it turned out to be not only modern and functional but BEAUTIFUL too! They also remodeled the adjacent laundry room and entrance and added a closet that, when completed, blended in perfectly with the room decor. I was very pleased with all that was done. Jake was easy to work with and provided helpful suggestions that I appreciated and used. The workers were super -- personable, skilled and professional, and punctual as well. As is often the case when working on an old house, there were a few unexpected problems that needed addressed before work on the bathroom could continue. I was both grateful and impressed that when the job was finished I was not charged a single penney above the price that I was quoted at the beginning. I would definitely recommend this company to anyone. In fact I have done just that and they are now contracted to do several projects for my daughter. Thank you so much Jake and staff!"

Egress Windows FAQs, answered by experts

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.

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.

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.  

There are a few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.
