How Installing Energy-Efficient Windows in Madison Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $420 a year on your bills.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Madison

Windows come in different purposes, shapes and styles, so costs and services will vary greatly based on several factors. Below, we detail the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Madison can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. This is because of the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Madison home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage or rot. Because these installations are more involved, they will raise the overall cost. 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.

If you’re unsure which kind of window installation service you should get, your installer should be able to assist you. Generally, the choice depends on 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 Madison

EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. We have assessed the best window installation companies in Madison primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When it comes to 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 opt for. 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

Customer feedback is another very important review factor. If most customers don’t have positive feedback about their experience with a certain window installation company, it won’t be 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 providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Madison’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Madison window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
