How Installing Energy-Efficient Windows in New Haven Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to consider making the switch:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In New Haven, you can cut your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade to energy-efficient windows.
  • Save on electricity bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in New Haven

When considering window installation, each company offers different services and prices. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Generally, homeowners in New Haven can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. How much it will cost varies based on several factors, such as the location of your home, number of windows, type, size, material and more.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $420 a year on your energy bills in New Haven.

Requesting free quotes from several companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step when planning a window installation is to think about whether you need a full-frame or pocket installation.

Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the full window, including the trim, sill and frame. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

If you’re still debating which type of installation to get, you can ask 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 New Haven

In our hunt to find the most reliable, eco-friendly window installers in New Haven, the EcoWatch Reviews team evaluated dozens of companies before settling on these. We have reviewed the best window installers in New Haven mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for New Haven, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in New Haven.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to New Haven’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of New Haven window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

New Haven, CT Window Replacement FAQs

How much does window installation cost?

The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

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

What services do window replacement companies provide?

Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

Should I replace all my windows at once?

If you’re upgrading your windows to save on your energy bills, replacing all of your windows together is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or drafty, you can replace just those.
