A review of the best window replacement companies in Derby may not seem like the most compelling article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might think. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could account for around 30% of heating and cooling costs. In Derby, where the electricity bills are an average of $35 per month, that's almost $$127 per year wasted.

Installing efficient windows on your house can help you save money each month on your power bills — and you can help the environment as well.

Efficient windows are of particular importance in Derby, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $453 a year.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Derby Saves You Money

Energy-efficient windows can benefit you in several ways. 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 it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save money on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Decrease your carbon footprint: In Derby, you can cut your indirect greenhouse gas emissions by about 460 pounds per year after you upgrade to energy-efficient windows.
  • More efficient energy use in your household: In Derby where the summers can be quite hot, energy-efficient windows lower how much cool air is lost through your windows, making it easier to keep your home cool.

Estimated Cost of Window Replacement in Derby

Windows come in various shapes, purposes and styles, so costs and services will differ tremendously depending on several factors. Below, we describe the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These amounts vary based on the specifics of your installation, such as number of windows, type, material, the location of your home, size and more.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $453 a year on your energy bills in Derby.

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

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window without taking out the complete frame, which is usually cheaper than a full-frame installation.

Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Derby

In our search to make your home improvements easier and more eco-friendly in Derby, the EcoWatch team evaluated dozens of companies before landing on these. We have assessed the top window installers in Derby mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Derby 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 you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, quality of parts, quality of installation, warranty, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Derby, CO Window Replacement FAQs

What is the typical cost to replace windows?

The typical cost of replacing one window ranges between $450 and $650. There are several factors that influence how much it costs, including how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, local labor costs, your property's location and the number of windows.

Which kind of window should I get?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.

How long does window installation take?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
