"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 professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

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. 

Hot water removes grime more efficiently than cold water and evaporates more quickly so that your windows will dry faster. However, you may want to use cold water instead if your windowsill paint is chipping or peeling because heat can worsen this condition.
