How Installing Energy-Efficient Windows in Medford Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- 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- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Medford
When researching window installation, each company offers different services and costs. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
Generally, Medford homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. Costs will vary significantly based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Medford homeowners $464+ per year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. Because these installations are more involved, they will increase the total cost. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Medford
In our hunt to find the most reliable, eco-friendly window installers in Medford, EcoWatch landed on the above companies as the best window installation companies in the city. We have evaluated the best window installers in Medford primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Medford so you can find a quality window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, quality of parts, professionalism and more.
Cost
Cheaper windows don’t necessarily 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Medford, MA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of installing a window is about $600 but can range between $200 and $1,200, based on a variety of 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, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
There are various types of windows you can get for your house, including picture windows, slider windows, transom windows, awning windows, casement windows, bay windows and double-hung and single-hung windows.
When do I have to use a window installation company?
Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
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. In addition, it shouldn’t be raining, since rain can make the installation harder.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or drafty, you can replace just those.
