How Installing Energy-Efficient Windows in Johnston City Saves You Money

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

  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Johnston City

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Though the national average to replace a single window is about $600, it can range anywhere from $200 to $1,200. These numbers are based on specific characteristics of your installation, like number of windows, the location of your home, type, material, size and more.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $291 a year on your energy bills in Johnston City.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the complete window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because full-frame installations are more involved, they will raise overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window replacement company will be able to help you choose what's best for your needs. In Johnston City, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Johnston City

EcoWatch reviews are different from most reviews since we examine these companies through a sustainability lens. We've evaluated the best window installation companies in Johnston City primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Johnston City, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Johnston City.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you get. 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 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 most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, quality of installation, warranty, professionalism and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores 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

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

Johnston City, IL Window Replacement FAQs

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

The typical cost of replacing a window ranges from $450 to $650. There are a variety of factors that influence how much it costs, such as how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, local labor costs, the number of windows and your property's location.

What type of window is the most energy-efficient?

A window's energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

You should use a window installation company whenever you want to replace your windows. Installing windows is a complex process that can take a lot of time, so it's best left to the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.

How do you know it's time to replace your windows?

Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
