How Installing Energy-Efficient Windows in Orange Saves You Money

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

  • Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • 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 your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Orange

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

How Much Do New Windows Cost?

Even though the typical of replacing one window is about $600, it can range anywhere from $200 to $1,200. But costs differ remarkably 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 installations and replacements, which have a higher price tag.

It's important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Orange homeowners $420+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Orange

In our hunt to make your home improvements easier and more eco-friendly in Orange, the EcoWatch team evaluated many companies before settling on these. We have evaluated the best window installers in Orange mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to 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 offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Orange, CT Window Replacement FAQs

What is the average cost to install new windows?

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

Which kind of window should I get?

A window's energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Do you really need to use a window installation company?

Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.

How long does it generally take to install windows?

Each window takes around 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, you probably need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
