How Installing Energy-Efficient Windows in Darby Saves You Money

When you switch to energy-efficient windows, you may see a few perks, including:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Better temperature control in your home: When you reside in a place like Darby where the summers can be quite hot, you often have to rely on your air conditioner to keep your house cool. Energy-efficient windows can reduce the amount of cool air lost through your windows when cooling your home.

Estimated Cost of Window Replacement in Darby

Let's take a look at the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in Darby can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs will differ significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Darby homeowners $316+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you're not sure which type of window installation service you should get, your installer should be able to help you out. Typically, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Darby

The EcoWatch Reviews team differs from other reviewers since we're examining these companies through a sustainability lens. We have reviewed the best window installers in Darby mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

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

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good 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.

Darby, PA Window Replacement FAQs

How much should a window install cost?

The national average cost of installing a window is about $600 but can range between $200 and $1,200, depending on several factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.

How long does it usually take to install windows?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
