How Installing Energy-Efficient Windows in Wiscasset Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could benefit you:
- Save on energy 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 you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Better temperature control in your home: Residing in a warm city like Wiscasset often means relying on your air conditioner to keep your house cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Wiscasset
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Wiscasset can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Wiscasset home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the total window, including the frame, sill and trim. A pocket installation involves replacing a window within the frame that's already there. So, instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which kind of window installation service you need, your installer should be able to advise you. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Wiscasset
EcoWatch reviews are different from other reviews because we're examining these companies through a sustainability lens. We've assessed the best window installers in Wiscasset mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Wiscasset so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor 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 earn higher rankings by our standards. We like to see at least ten years of experience.
Wiscasset, ME Window Replacement FAQs
How much does a window install cost?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the location of your property, the type and material of the window and the size 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 most common kinds of replacement windows?
There are several different types of windows you can get for your house, such as picture windows, double-hung and single-hung windows, casement windows, awning windows, transom windows, bay windows and slider windows.
Do you really have to use a window installation company?
You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best handled by the professionals.
How long does it take to install windows?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows together 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.
