How Installing Energy-Efficient Windows in Fairfield Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

  • Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Better temperature control in your home: When you reside in a city like Fairfield where the winters can get very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.

Estimated Cost of Window Replacement in Fairfield

When looking into window installation, each company offers varying services and costs. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Fairfield homeowners $441+ each year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler 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 unsure which kind of window installation service you should get, your installer should be able to assist you. In general, the choice 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 Fairfield

The EcoWatch Reviews team differs from most reviewers since we look at these companies through a sustainability lens. We have reviewed the top window installation companies in Fairfield mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Fairfield so you can find a quality window installation company near you.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window installers won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Fairfield, CT Window Replacement FAQs

How much should a window install cost?

The average cost to install a window ranges between $450 and $650. There are a variety of factors that affect the price, such as the materials used in designing the windows, how energy-efficient the windows are, your property's location, styles and sizes of windows, local labor costs and the number of windows.

What are the kinds of windows?

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

When do I 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 complex and can take anywhere from four to six hours for a single 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 window installation generally take?

Because a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.

Should I replace all my windows at once?

If you're upgrading your windows to get more efficient windows, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
