How Installing Energy-Efficient Windows in Medford Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating 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: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Decrease your carbon footprint: In Medford, you can reduce 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
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you'll find from window installation companies.
How Much Do New Windows Cost?
Generally, Medford homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. But costs will vary considerably depending on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Something else that influences the total cost is the material of the frame you choose. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler 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 installation company should be able to help you choose what's best for your needs. In Medford, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Medford
In our search to find the most reliable, eco-friendly window installers in Medford, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in Medford and ranked them based on the following methodology:
Service Area
Since this is a guide for Medford, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Medford.
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 featured in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, professionalism, quality of parts, quality of installation and more.
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 the prices of providers, we gave higher points 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 protected. Window installation companies that offer 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 proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Medford, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single 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 location of your property 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 different kinds of windows?
The most common types of windows for homes are slider windows, transom windows, awning windows, double-hung and single-hung windows, bay windows, casement windows and picture windows.
What services do window installation companies provide?
Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
