How Installing Energy-Efficient Windows in Lackawanna Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $368 annually on your energy bills in Lackawanna.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Lackawanna
When looking into window installation, each company provides varying services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
Generally, homeowners in Lackawanna can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. Costs will differ significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
It’s important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Lackawanna homeowners $368+ a year when replacing single-pane windows.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the frame that’s already there. This means instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Lackawanna, the decision will mostly depend on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Lackawanna
In our search to make your home improvements easier and more eco-friendly in Lackawanna, EcoWatch chose the above companies as the top window installation companies in the city. We have reviewed the best window installation companies in Lackawanna mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy 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 a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. 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 online reviews 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 most other categories, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

The most common types of windows for homes are slider windows, bay windows, casement windows, transom windows, picture windows, awning windows and double-hung and single-hung windows.
What services do window replacement companies do?
Window installation companies will do the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.
Should I replace all my windows at the same time?
