That's also bad for the environment, as the additional energy required by leaky windows increases your carbon footprint.

We've made a guide on the top installation companies to help you in your search, so you can not only benefit from brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Northglenn Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

  • Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 460 pounds.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Northglenn

Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

Typically, Northglenn homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will add extra costs to your project.

It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Northglenn home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Getting free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window replacement company should be able to help you figure out what's best for your needs. In Northglenn, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Northglenn

In our hunt to make your home improvements easier and more eco-friendly in Northglenn, EcoWatch examined dozens of companies before settling on these. We've decided to evaluate the best window installers in Northglenn mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Northglenn, we paid more attention to 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 Northglenn.

Work Quality

When picking 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 opt for. We do give window installers higher marks 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 most customers don't have nice things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

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

Warranty

As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience will 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 typical cost of replacing one window can range between $450 and $650. There are several factors that influence the cost, which include how energy-efficient the windows are, your property's location, the materials used in designing the windows, local labor costs, styles and sizes of windows and the number of windows.

What are the different kinds of windows?

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

Can I replace my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.

How long does it usually take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.

Should I replace all my windows at the same time?

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