How Installing Energy-Efficient Windows in Derby Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Decrease your carbon footprint: In Derby, you can reduce your indirect greenhouse gas emissions by about 460 pounds per year after you install energy-efficient windows.
  • Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $453 annually on your energy bills in Derby.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Derby

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

How Much Do New Windows Cost?

On average, homeowners in Derby can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. How much it will cost you depends on several factors, like size, material, type, the location of your home, number of windows and more.

It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Derby home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

When it comes to window replacements, there are generally two kinds that your installer will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need 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 decision depends 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 Derby

In our hunt to make your home improvements easier and more eco-friendly in Derby, the EcoWatch team evaluated many companies before settling on these. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. 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

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

Cost

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

Warranty

Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Derby, CO Window Replacement FAQs

What is the average cost to replace windows?

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

What are the most common types of replacement windows?

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

What do window installers do?

Window installers cover the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.

How long does it usually take to install windows?

Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.

Should I replace all my windows at once?

If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
