How Installing Energy-Efficient Windows in Florissant Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save $376 a year on your bills.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 763 pounds.

Estimated Cost of Window Replacement in Florissant

Each window replacement company offers various services and has different costs based on a few factors.

How Much Do New Windows Cost?

Generally, Florissant homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. This is due to the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Florissant homeowners $376+ per year after replacing single-pane windows.

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

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your installers will replace the total window, including the frame, trim and sill. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're not sure which window installation service you should get, your installer should be able to help you out. In general, the decision is influenced by 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 Florissant

EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Florissant and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Florissant, 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 they wouldn't be able to serve homeowners in Florissant.

Work Quality

When installing new windows, the quality and variety of services often plays 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 customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, warranty, cost, professionalism and more.

Cost

Cheaper windows certainly don't 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 awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Florissant, MO Window Replacement FAQs

How much should window installation cost?

The national average cost of installing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

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're getting the most energy-efficient windows, look for models with 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 installation companies offer?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.

How long does window installation typically take?

Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
