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.

"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

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.

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.

When planning egress window installation, costs can vary due to factors like window type, materials, labor, permits, and structural engineer consultations. The average price typically falls between $2,500 to $5,300 or more, depending on location. Considering these aspects is crucial to budget for the project and ensure compliance with local regulations. Obtaining multiple quotes and professional guidance is recommended to comprehensively understand expenses related to egress window installation in your area.

Installing two windows typically takes 2-4 hours, depending on accessibility and preparation.

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.
