How Installing Energy-Efficient Windows in Sullivan Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 763 pounds.
  • Save money on energy 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.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Sullivan

When researching window installation, each company offers varying services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Typically, Sullivan homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost you varies based on several factors, including size, type, the location of your home, material, number of windows and more.

It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Sullivan home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We advise getting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Sullivan

In our search to make your home improvements easier and more eco-friendly in Sullivan, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Sullivan, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Sullivan.

Work Quality

When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good 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.

Sullivan, MO Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

The most common kinds of windows for homes include: double-hung and single-hung windows, slider windows, picture windows, bay windows, awning windows, casement windows and transom windows.

Can I install my own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.

What time of year is a good time to replace my windows?

Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
