How Installing Energy-Efficient Windows in Dunlap Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to think about making the switch:

  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 622 pounds per year on average.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $384 a year on your bills.

Estimated Cost of Window Replacement in Dunlap

Let's go over the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Typically, homeowners in Dunlap can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which have a higher price tag.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Getting free quotes from several providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first step when planning a replacement is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Dunlap

EcoWatch is different from other reviewers since we're examining these companies through a sustainability lens. We have decided to evaluate the top window replacement companies in Dunlap primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Dunlap so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you choose. 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 online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, warranty, quality of parts, cost and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Dunlap, IN Window Replacement FAQs

How much should a window install cost?

The average cost to install one window can range from $450 to $650. There are a variety of factors that influence how much it costs, which include the number of windows, your property's location, styles and sizes of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.

Which kind of window is the best?

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

When should I use a window installation company?

Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.

How long does window installation generally take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.

Should I replace all my windows at once?

If your windows are more than 20 years old, it's probably time 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 once will involve less paperwork and less time.
