How Installing Energy-Efficient Windows in Upper Providence Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 286 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Save money on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.

Estimated Cost of Window Replacement in Upper Providence

When considering window installation, each company provides different services and costs. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Generally, Upper Providence homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. These estimates vary depending on specific characteristics of your installation, such as size, number of windows, type, the location of your home, 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 a year when you replace single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window without taking out the whole frame, which is generally cheaper than a full-frame installation.

If you’re not sure which type of window installation service you need, your installer should be able to help you out. Typically, the decision is influenced by 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 Upper Providence

In our search to make your home improvements easier and more eco-friendly in Upper Providence, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Upper Providence, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Upper Providence.

Work Quality

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

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Upper Providence, PA Window Replacement FAQs

How much should a window install cost?

The average cost to install a window can range between $450 and $650. There are many factors that affect how much it costs, including the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, the number of windows and your property’s location.

What type of window is the best for energy efficiency?

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

Can you replace your own windows?

If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don’t have the time or know-how, we recommend hiring a professional.

How long does it typically take to install windows?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
