How Installing Energy-Efficient Windows in Missoula Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

• Reduce your carbon footprint: In Missoula, you can lower your indirect greenhouse gas emissions by about 318 pounds per year once you switch to energy-efficient windows.
• Save money on electricity bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $433 annually on your energy bills in Missoula.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Missoula

Let’s go over the cost of window replacement and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Though the typical cost of replacing one window is about $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, like the location of your home, type, material, size, number of windows and more.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

When considering window replacements, in general there are two types that your installer will have: full-frame and pocket installations.

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 simpler 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 hiring a reputable window installation company, your company can recommend the best type for your project. In Missoula, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Missoula

In our search to make your home improvements easier and more eco-friendly in Missoula, the EcoWatch Reviews team examined many companies before landing on these. We’ve decided to review the best window installation companies in Missoula mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of 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 installation, quality of parts, warranty, cost, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
