How Installing Energy-Efficient Windows in Barrington Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could benefit you:

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
• Reduce your carbon footprint: In Barrington, you can lower your indirect greenhouse gas emissions by about 449 pounds per year after you switch to energy-efficient windows.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Barrington

Let’s go over the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. This is because the cost of window installations depend on several 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 choose energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $295 a year on your energy bills in Barrington.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window replacement is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which type of window installation service you need, your installer can advise you. In general, the decision 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 Barrington

EcoWatch differs from other reviewers, as we look at these companies through a sustainability lens. We have reviewed the best window replacement companies in Barrington mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Barrington, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Barrington.

Work Quality

When selecting 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 opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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