How Installing Energy-Efficient Windows in Montclair Saves You Money

When you switch to energy-efficient windows, you may see several benefits, such as:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • Save money on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Montclair, that’s about 117 pounds per year on average.

Estimated Cost of Window Replacement in Montclair

Each window installation company provides various services and has different price points depending on a few factors.

How Much Do New Windows Cost?

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

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Montclair homeowners $540+ each year after replacing single-pane windows.

The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, there are typically two types that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation entails installing a new window within the old frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Montclair, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Montclair

In our search to make your home improvements easier and more eco-friendly in Montclair, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated 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 the Montclair area so you can find the right window installation company near you.

Work Quality

When selecting 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 of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find 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 indicates the quality of services across most other categories, including quality of installation, cost, quality of parts, warranty, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, 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 with lengthy warranties for products, parts and labor 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Montclair, CA Window Replacement FAQs

How much does a window install cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the different kinds of windows?

The most common types of windows for homes are double-hung and single-hung windows, slider windows, awning windows, bay windows, picture windows, transom windows and casement windows.

Do I really need to use a window installation company?

You should hire a window installation company whenever you want to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
