How Installing Energy-Efficient Windows in Medford Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: In Medford, you can lower your indirect greenhouse gas emissions by about 307 pounds per year when you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Medford
When considering window installation, each company provides varying services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
Even though the typical cost to replace a single window is around $600, it can range from $200 to $1,200. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Medford homeowners $215+ each year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you’re still debating which type of installation you need, you can talk to your provider and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Medford
EcoWatch is different from most reviewers since we examine these companies through a sustainability lens. We’ve decided to assess the best window installers in Medford primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Medford, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Medford.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have nice things to say about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have 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 proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Medford, NY Window Replacement FAQs
What is the average cost to replace windows in a home?
The average cost of replacing a single window ranges from $450 to $650. There are several factors that affect how much it costs, such as your property’s location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, styles and sizes of windows and local labor costs.
What are the kinds of windows?
There are several different types of windows you can get for your home, including bay windows, slider windows, picture windows, casement windows, awning windows, double-hung and single-hung windows and transom windows.
What services do window installation companies provide?
Window installation companies will do the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
