How Installing Energy-Efficient Windows in Winslow Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- More efficient energy usage in your household: In Winslow where the winters can be cold, energy-efficient windows reduce the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
- Better temperature control in your home: When you live in a city like Winslow where the summers can be pretty warm, you often have to depend on your air conditioner to keep your house cool. Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
Estimated Cost of Window Replacement in Winslow
Windows come in various purposes, shapes and styles, so costs and services will vary remarkably depending on several factors. Below, we detail the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost you depends on several factors, such as number of windows, size, the location of your home, type, material and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $435 a year on your energy bills in Winslow.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're still debating which type of installation to get, you can consult with your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Winslow
In our search to make your home improvements easier and more eco-friendly in Winslow, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Winslow and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Winslow, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Winslow.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list 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
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Winslow's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Winslow window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Winslow, ME Window Replacement FAQs
How much should window installation cost?
The typical cost to install a window can range between $450 and $650. There are many factors that affect how much it costs, including local labor costs, how energy-efficient the windows are, your property's location, styles and sizes of windows, the materials used in designing the windows and the number of windows.
What type of window is the most energy-efficient?
A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installers cover the entire process — from replacing your 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.
How long does it usually take to install windows?
Since a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
