How Installing Energy-Efficient Windows in Lombard Saves You Money

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

• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Lombard, that’s about 449 pounds per year on average.

Estimated Cost of Window Replacement in Lombard

Let’s go over the cost of window installation and the types of services offered by installers.

How Much Do New Windows Cost?

Although the national average cost of installing a single window is about $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $300 a year on your energy bills in Lombard.

Another factor that affects the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails installing a new window within the frame that’s already there. So, instead of removing the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lombard

In our hunt to find the most reliable, eco-friendly window installers in Lombard, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Lombard and ranked them based on the following methodology:

Service Area

Since this is a guide for Lombard, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Lombard.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find 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 reflects the quality of services across most other categories, including cost, quality of installation, professionalism, quality of parts, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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