How Installing Energy-Efficient Windows in Spencer Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 139 pounds.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Spencer

Each window installation company provides varying services and has different price points based on several factors.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ considerably based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.

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

We advise requesting free quotes from several window installation companies to find the one that works best for you.

What Services do Window Installers Offer?

In regard to window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the entire window, including the sill, frame and trim. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re unsure which window installation service you need, your installer should be able to help you out. Typically, the decision 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 Spencer

EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. We have decided to review the top window installers in Spencer mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

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 a quality window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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