"American Home Renewal recently replaced 7 double hung windows in our home. We had 3 window replacement companies come to our home discuss the process and give us estimates. Chris from American Home Renewal was by far the most professional. He spent time with us, accurately described the entire installation process with us and exhibited willingness and patience to hear and understand what we were looking for in the new windows. The American Home Renewal contract was clear, concise and straight forward. The 3 day installation process was fluid and fairly quiet and we were able to work from home. It had a minimal impact on our lives. The crew cleaned up thoroughly every day and took time to make sure we knew how to tilt the windows for eventual cleaning etc. Keith, the Production Manager, checked in a few times during the 3 day installation period to ensure everything was progressing to our satisfaction. We could not be more pleased with American Home Renewal's level of professional service and care."

Windows questions, answered by experts

Most modern egress windows installed in basements open outward into a window well, although some older homes have in-swing windows. Egress windows, like casement windows used in other parts of the home, such as bedrooms and bathrooms, may open inward, and these windows are often larger than outward-opening windows.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Having a professional caulk your windows will cost you around $50 to $70 per window (or $1.25 to $4 per linear foot), including labor. However, caulking is one of the easiest DIYs there is, and you’ll save a lot of money by getting the supplies and doing it yourself. You’ll only pay $0.05 to $0.20 per linear foot if you DIY this one. Finally, different types of caulk don’t vary too much in price, with most tubes costing no more than $15 apiece (but typically only $3 to $10) at the most. 

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

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.
