Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could make up nearly 30% of heating and cooling use. In Saco, where the electricity bills are an average of $30 per month, that's almost $$108 per year wasted.
That's not great for either your wallet or the environment, but one of the best window installation companies can help with that.
Because windows are so important for your home, choosing the right company for you is a big decision to make. That's why the EcoWatch team has made this list of the top window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Saco Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could benefit you:
- Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Saco
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Even though the average of replacing one window is about $600, it can range from $200 to $1,200. But costs will vary considerably based on the quality of your products, your location, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Saco homeowners $383+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step of a replacement is to decide whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Saco
EcoWatch is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When picking 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 of window you opt for. 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
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Saco's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Saco window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Saco, ME Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending 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 upfront but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
There are several different types of windows you can get for your home, such as picture windows, transom windows, casement windows, bay windows, double-hung and single-hung windows, awning windows and slider windows.
Can I replace my own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don't have the time or experience, we don't recommend trying it.
How do you know it's time to replace your windows?
Windows typically last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually 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.
