How Installing Energy-Efficient Windows in Sanford Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, including:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Better temperature control in your home: Living in a warm city like Sanford often means depending on your air conditioner to keep your home cool. Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Sanford

Each window replacement company provides various services and has varying price points depending on several factors.

How Much Do New Windows Cost?

According to our research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost you depends on several factors, like type, material, number of windows, the location of your home, size and more.

It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Sanford homeowners $383+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Sanford

In our search to find the most reliable, eco-friendly window installers in Sanford, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Sanford area so you can find the right window installation company near you.

Work Quality

When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand 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

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Sanford's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Sanford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Sanford, ME Window Replacement FAQs

How much does window installation cost?

The typical cost to install a single window ranges between $450 and $650. There are many factors that affect the cost, including local labor costs, the materials used in designing the windows, the number of windows, your property's location, styles and sizes of windows and how energy-efficient the windows are.

Which type of window should I get?

A window's energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don't have the time or experience, we recommend hiring a professional.

How long does it generally take to install windows?

Because the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
