How Installing Energy-Efficient Windows in Affton Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, including:

  • Better temperature control in your home: Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.

Estimated Cost of Window Replacement in Affton

Windows come in various purposes, styles and shapes, so costs and services will vary tremendously based on your project. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But prices 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 provide door installations and replacements, which will add extra costs to your project.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most 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?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you're unsure which type of window installation service you need, your installer can help you out. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Affton

In our hunt to make your home improvements easier and more eco-friendly in Affton, the EcoWatch Reviews team examined many companies before landing on these. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:

Service Area

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

Work Quality

When picking new windows, the quality and range of services often plays 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

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won't always provide the most quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Replacement windows can be installed at any time, but warmer weather is typically better.

What's most important is that the weather should be dry.
