How Installing Energy-Efficient Windows in Darby Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
• Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Darby

Let’s take a look at the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our market research, the typical cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, such as number of windows, the location of your home, type, size, material and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

We recommend requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first step when considering a replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which kind of installation you should get, you can talk to your provider and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Darby area so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
