How Installing Energy-Efficient Windows in Montclair Saves You Money

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

  • 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Save on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Montclair

Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in Montclair can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. Costs will differ significantly based on the number of windows you need, the quality of your products, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Montclair 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.

Getting free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first step of a replacement is to figure out whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Montclair

In our search to find the most reliable, eco-friendly window installers in Montclair, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Montclair, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Montclair.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in 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 factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, 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. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Montclair, VA Window Replacement FAQs

How much should a window install cost?

The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is often dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you replace your own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or skills, we recommend getting a professional to do it for you.

Should I replace my windows all at once?

If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at the same time is the only way to gain that benefit. However, if you have only one or two windows that are damaged or drafty, you can replace just those.

How long does window installation typically take?

Since the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
