How Installing Energy-Efficient Windows in Medford Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Save on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Reduce 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.
Estimated Cost of Window Replacement in Medford
Each window installer provides various services and has varying price points based on several factors.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will make your project cost more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Medford homeowners $215+ each year after replacing single-pane windows.
Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using 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 offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you decide what's best for your needs. In Medford, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Medford
EcoWatch is different from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Medford, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Medford.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't 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 previously, windows are a serious 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
Because of Medford's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Medford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Medford, NY Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window's energy efficiency depends on a number of factors, such as 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 I install my own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or experience, we recommend getting a professional to do it for you.
How long does window installation usually take?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
