"WOW! Groundworks is a great, reliable company! We had the dream team, Ryan, Alejando (Alex) and Jose, working on our home. Ryan kept us informed on what was going on the during the whole project. Ryan and Alex were so reassuring of all our fears and concerns, we knew we were in good hands. Alex and Jose were so polite and talk about hard working!! All three of them went above and beyond, exceeding our expectations, saving some landscaping we didn't expect to be saved. They took great care with our landscaping and yard and did not cause any unexpected damage to any of it! They did a great job with the clean-up at the end of the job as well. These three men worked great together as a team. We were happy to see them everyday and a little sad when we said good bye."

Egress Windows questions, answered by experts

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.  

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

The primary benefits of an egress window include providing a safe emergency exit, increasing natural light in a space like a basement, and improving ventilation. Additionally, installing an egress window can often increase your property's value.

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.

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• What experience do you have installing egress windows?

• Can you provide references from previous customers?

• Do you perform the work yourself or use subcontractors?

• What is the estimated project timeline and your current schedule?

• How do you handle payment?
