It's how we do business and we hope you will recommend us to your family and friends. Member of the Better Business Bureau of Maryland with A+ rating and zero complaints. Special discounts for all Angie's List members.

"We recently had Chesapeake Thermal come out to replace 12 windows and 2 patio doors (as well as cap a bay window.) Matt, Nancy, and John were super easy to work with to get a quote on the replacement of our original 30 yr windows. The turnaround time between initial deposit and installation was ~11 weeks; a timeframe likely impacted by the uncertainty of the ongoing pandemic. With regard to installation, Sang (and team) did a phenomenal job. They were able to finish most of the install in one day, with some additional capping work finished two days later. The difference in comfort between our original windows and replacements is dramatic. We've noticed our HVAC rarely turning on now, and the comfort across the various levels of our townhome seems to be considerably more stable. We were really impressed from start to end, and wouldn't hesitate to use them again."

Egress Windows questions, answered by experts

The installation process for your egress window project will span three days for three stages. On day one, excavation will occur. Day two involves cutting the foundation, and day three will focus on window installation and insulation. Remember that the number of windows you install will impact the days needed. Additionally, you may want a couple of helpers to help you speed through day one.

DIY is possible with proper tools and knowledge. Professional installation ensures a proper seal and energy efficiency.

A bow window costs up to $15,000 to install in total. Materials cost anywhere from $1,200 to more than $14,000, and labor is an additional $300 to $1,900. Bow window costs vary based on the size of the window and the frame material. You’ll spend more for custom features or energy-efficient upgrades, too. For comparison, bay window installation costs about $1,000 to $7,000. 

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.

Here are a few questions to ask a egress window contractor you’re considering hiring to install a new window:

  • Are you licensed and insured?

  • What experience do you have installing egress windows?

  • How long will the project take?

  • How do you handle payment?

  • Do you do the work yourself or do you hire subcontractors?

  • Can I talk to some of your previous customers?

  • Do you have references and a portfolio of your work?

  • What is your schedule for getting the job done?
