How Installing Energy-Efficient Windows in Northglenn Saves You Money

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

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • 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.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save $455 a year on your bills.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Northglenn

Each window installer provides varying services and has different costs depending on a few factors.

How Much Do New Windows Cost?

Generally, homeowners in Northglenn can anticipate that most window installations will range from $250 to $1,200, with the average cost at about $600. These estimates are based on specific characteristics of your installation, such as the location of your home, number of windows, size, type, material and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Northglenn homeowners $455+ a year after replacing single-pane windows.

We advise requesting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. Because full-frame installations are more involved, they will raise overall costs. Pocket installations are on the simpler end and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you're not sure which kind of window installation service you should get, your installer can assist you. In general, the choice is based on 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 Northglenn

In our search to find the most reliable, eco-friendly window installers in Northglenn, the EcoWatch team examined many companies before deciding on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Northglenn, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Northglenn.

Work Quality

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

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Northglenn, CO Window Replacement FAQs

What is the average cost to install new windows in a home?

The average cost of installing a single window can range from $450 to $650. There are several factors that influence how much it costs, such as the materials used in designing the windows, the number of windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and your property's location.

What are the different kinds of windows?

There are various kinds of windows you can get for your home, including picture windows, casement windows, double-hung and single-hung windows, transom windows, slider windows, awning windows and bay windows.

Can you replace your own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. But if you don't have the time or know-how, we don't recommend doing it on your own.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.

Should I replace all my windows at once?

If you're upgrading your windows to save on your energy bills, replacing all the windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or leaky, you can replace just those.
