How Installing Energy-Efficient Windows in Franklin Park Saves You Money

There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

  • Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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.
  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Franklin Park

Each window replacement company provides varying services and has varying prices based on several factors.

How Much Do New Windows Cost?

Generally, Franklin Park homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. How much it will cost varies depending on several factors, like the location of your home, type, size, material, number of windows and more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Franklin Park homeowners $313+ a year after replacing single-pane windows.

We advise getting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the trim, sill and frame. A pocket installation entails replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company can recommend the best type for your project. In Franklin Park, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Franklin Park

In our search to make your home improvements easier and more eco-friendly in Franklin Park, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Franklin Park and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

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

Warranty

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

Years of Experience

Because of Franklin Park’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Franklin Park window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Franklin Park, PA Window Replacement FAQs

What is the typical cost to install new windows?

The national average cost to install a window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

There are several different kinds of windows you can get for your house, including double-hung and single-hung windows, transom windows, slider windows, picture windows, casement windows, bay windows and awning windows.

What do window installation companies do?

Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.

Should I replace all my windows at the same time?

If you’re upgrading your windows to get more efficient windows, replacing all of the windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are damaged or drafty, you can replace just those.

How long does it take to install windows?

Because the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
