How Installing Energy-Efficient Windows in Saco Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

  • Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Saco

Windows come in varying shapes, purposes and styles, so costs and services will vary considerably based on your project. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Typically, Saco homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These estimates are based on the specifics of your installation, like the location of your home, number of windows, type, size, material and more.

Whether or not you want to install 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 $383 a year on your energy bills in Saco.

Another factor that influences the total cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window installation is to clarify whether you want a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation involves installing a new window within the frame that’s already there. 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.

If you’re still trying to decide which kind of installation you need, you can consult with your provider and get their recommendation. 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 Saco

The EcoWatch Reviews team differs from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Saco, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Saco.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Saco’s climate, homeowners need to be wary of 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 does a window install cost?

The typical cost of installing one window can range between $450 and $650. There are many factors that affect the price, such as local labor costs, styles and sizes of windows, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and your property’s location.

What type of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installation professionals will do the entire process — from replacing your old windows with brand-new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.

What time of year is a good time to replace my windows?

Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation more difficult.

How often should you replace your windows?

Windows generally have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
