"Egress Inc was friendly, pleasant and did a great job on the window.  It was one of the most seemless experiences I've had.  I would recommend Egress to anyone!

"They replace window wells which is not one of the categories here. The Window Well Guardian people are fast on returning calls and providing a quote. They were an excellent value and I would definitely use them again. What a dedicated team. They hand dug out the old window wells during a snow storm. Impressive!"

"Truly a family business. Drew and his crew carefully replaced all the windows in my 1910 Bungalo. He also helped repair an original window and install a custom door. Their prices are fair and there was good communication and attention to detail. No job to big or small. Have referred him to several of my friends."

Windows questions, answered by experts

Sometimes, you can buy windows directly from the manufacturer, and it may be cheaper than buying through a third party or wholesaler. Manufacturers may also offer more options, including custom shapes and features, or better warranties if you purchase through them directly. 

However, some companies limit the ability to buy from them, especially if you need standard pre-fabricated sizes, so don’t expect this service from every manufacturer.

Mulled windows are often more expensive than standalone windows. However, this is mostly because mulled windows tend to be larger than standard windows, meaning they require more materials and labor to manufacture and install, both of which drive up the cost. If mulled windows take up the same square footage as separate windows, they should cost about the same unless you need to reinforce your exterior wall to support the larger wall opening.

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.

Installing energy-efficient windows costs between $325 and $2,000, averaging about $400 per window. You’ll have to consider cost factors like the window’s size, frame material, and type. Labor costs in your area will also impact the overall cost of the project, with window installation professionals charging about $40 per hour on average. Different types of energy-efficient windows include:

  • Single-hung: $150–$2,500

  • Casement: $150–$600

  • Double-hung: $250–$3,000

  • Picture: $200–$650

  • Bay: $480–$1,920

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.
