Why Should I Consider Replacing My Old Windows?

There are several reasons homeowners should consider replacing their old windows. Unlike old windows that have shifted along with the foundation of the house over the years, new replacement windows fit properly and are perfectly aligned with the wall’s opening. As residential security windows become more popular, you might want to switch out the old for the new. New windows also give your home added beauty, security, and energy efficiency due to advanced technological developments in the window industry. After you replace your existing windows with new, energy-efficient ones, you should see your energy bills decrease over time.

Is All Glass Used in Replacement Windows the Same?

No, there are several different types of glass you can use for windows. Each option offers various levels of energy efficiency and safety. Our window professionals can discuss options with you and help you choose the best type of glass for your needs.

What Should I Look for in a Replacement Window Warranty?

Your replacement window warranty should reflect the quality of the product you’re using. At J&M Windows and Glass, we are honest about our warranty policies with our customers and have extensive knowledge about their coverage. Our warranties vary depending on the manufacturer and window type, but most of our replacement windows are covered anywhere from 10 to 20 years.

What Are Various Windows Made of and What Will Work Best for Me?

There are four basic materials used in making residential house windows:

Aluminum – Aluminum or metal residential windows are typically used in commercial settings due to their durability. Because aluminum is an excellent conductor of heat and cold, residential use is usually not recommended.
Wood – Wood windows are usually the conventional choice for new construction, but they typically require more maintenance than other window types. Over time, most homeowners discover they need caulked, painted, and eventually replaced. Some manufacturers we work with offer a wood replacement window with an extruded aluminum or vinyl exterior that will prevent problems associated with original wood windows.
Fiberglass – Fiberglass windows are known for their strength and durability, as well as the large variety of interior and exterior design color choices available. Fiberglass windows are usually highly energy-efficient and come in unique style options, including residential stained glass windows.
Vinyl – Vinyl windows offer excellent insulation, don’t need to be painted, and won’t rot over time. As part of an effort to market more maintenance-free homes, the construction industry has started installing vinyl windows in new homes.

What Are the Signs That Windows Need Replacing?

It’s important to know what to look for when considering whether or not your windows need replacing. Visible damage, such as cracks and warping, is an obvious sign your windows need to be replaced. Another indication your windows need to be replaced is if you have a hard time opening or closing them. If you feel drafts when walking by your windows, they most likely need replacing.

Is Replacing All the Windows Necessary?

If several windows you have need replaced, it might be a good idea to have them all replaced so you won’t need to go through the process again soon. It’s not necessary to replace all your windows at once, so if you only have a couple that needs to be replaced, you can do a small-scale replacement project instead.

What Is the Best Time to Replace Windows?

Contrary to popular belief, replacing windows can be done at any time of the year. Window installation, when done by professionals, is a quick and easy process.

What Are the Best Residential Windows’ Materials?

For the most long-lasting window options, choose fiberglass, aluminum, wood, or vinyl. Keep in mind that while wood is durable and can add a beautiful aesthetic to your home, it will have to be repainted or maintained more often than the other options.
