How Installing Energy-Efficient Windows in Pontiac Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Save money on power bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
• Decrease your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Pontiac

Each window installer offers various services and has different costs based on several factors.

How Much Do New Windows Cost?

Though the typical cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will make your project cost more.

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

Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide 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?

There are generally two types of window replacement services: 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 to change the style of your window or when it has a great amount of damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to help you choose what’s best for your needs. In Pontiac, the decision will mostly be based on how old your windows are 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 examine your frames and window sills.

How We Choose the Best Window Installers in Pontiac

The EcoWatch Reviews team differs from other reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
