How Installing Energy-Efficient Windows in Northfield Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Northfield

Let’s take a look at the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, Northfield homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. How much it will cost varies based on several factors, such as size, number of windows, the location of your home, type, material and more.

Whether or not you pick 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 Northfield.

Something else that affects the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Northfield

In our search to find the most reliable, eco-friendly window installers in Northfield, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window 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

Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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