How Installing Energy-Efficient Windows in Norwalk Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Reduce your carbon footprint: In Norwalk, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year once you switch to energy-efficient windows.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Norwalk

Let’s take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

Typically, Norwalk homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. 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 companies also offer door installations, which will add extra costs to your project.

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

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable deterioration. These installations are more involved and will raise the overall cost. Pocket installations are on the simpler end and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you’re still debating which kind of installation you should get, you can talk to your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Norwalk

In our search to find the most reliable, eco-friendly window installers in Norwalk, EcoWatch examined dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Since this is a guide for Norwalk, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Norwalk.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

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 service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when 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 previously, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Norwalk, CT Window Replacement FAQs

What is the typical cost to replace windows in a home?

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

What kind of window is the best for energy efficiency?

A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you replace your own windows?

If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. But if you don’t have the time or skills, we recommend hiring a professional.

How often should you replace windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

How long does window installation take?

Since the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
