How Installing Energy-Efficient Windows in Winterport Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Winterport
Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs will vary significantly based on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $445 a year on your energy bills in Winterport.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're still debating which type of installation you need, you can talk to your installer and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Winterport
EcoWatch differs from other reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Winterport and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Winterport so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Winterport's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Winterport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Winterport, ME Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of installing a window ranges from $450 to $650. There are a variety of factors that influence how much it costs, which include styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property's location and the number of windows.
What are the different kinds of windows?
The most common kinds of windows for homes are transom windows, slider windows, picture windows, bay windows, awning windows, double-hung and single-hung windows and casement windows.
Can you replace your own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it usually take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
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 the windows at once is the only way to gain that benefit. However, if you have just a few windows that are damaged or leaky, you can replace just those.
