How Installing Energy-Efficient Windows in Hannibal Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, such as:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: In Hannibal, you can lower your indirect greenhouse gas emissions by about 763 pounds per year when you install energy-efficient windows.
• Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
• Save money on energy bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $387 annually on your energy bills in Hannibal.

Estimated Cost of Window Replacement in Hannibal

Let’s go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

Although the average cost of installing a single window is about $600, it can range from $200 to $1,200. These numbers are based on the specifics of your installation, such as size, material, type, the location of your home, number of windows and more.

It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Hannibal home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether 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 shown to be more efficient.

What Services do Window Installers Offer?

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

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation to get, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Hannibal

EcoWatch differs from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer 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 positive feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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