How Installing Energy-Efficient Windows in Old Lyme Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Old Lyme, that's about 147 pounds per year on average.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
  • 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: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in Old Lyme

Windows come in different purposes, styles and shapes, so costs and services will vary considerably depending on several factors. Below, we describe the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

On average, Old Lyme homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost you varies depending on several factors, like size, type, number of windows, the location of your home, material and more.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in Old Lyme.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when getting new windows is: Do you need 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 to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window installation company can recommend the best type for your project. In Old Lyme, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Old Lyme

In our hunt to make your home improvements easier and more eco-friendly in Old Lyme, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Old Lyme so you can find the best window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has received plenty 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 good feedback about their service from a certain company, you won't see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a hefty 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

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Old Lyme, CT Window Replacement FAQs

How much does window installation cost?

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

What are the most common kinds of replacement windows?

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

Can I install my own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

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.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
