Whether you're doing home renovations or have damaged windows, windows play a vital role in conserving your home's energy. During the winter months, the last thing you want is your heat to leak out of your outdated windows.

That's also bad news for the environment, as the extra energy required by old windows increases your carbon footprint.

How Installing Energy-Efficient Windows in Stamford Saves You Money

There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Stamford

Each window installation company offers various services and has different price points based on a few factors.

How Much Do New Windows Cost?

Though the national average of replacing one window is about $600, it can range anywhere from $200 to $1,200. But costs vary 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, which carry a higher price tag.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $459 a year on your energy bills in Stamford.

Requesting free quotes from multiple companies is the best way to find out which one will work best for your budget.

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 entail replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has considerable rot. Because full-frame installations are more involved, they will raise the total cost. 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 debating which kind of installation you need, you can talk to your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Stamford

In our search to make your home improvements easier and more eco-friendly in Stamford, the EcoWatch team evaluated many companies before landing on these. We have decided to review the top window installation companies in Stamford mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Stamford, we only included companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Stamford.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer on this list to ensure its contractors are well-qualified and that the company has received lots 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 consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, 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

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

What do window installers do?

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

When is it time to replace your windows?

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

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 gain that benefit. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
