How Installing Energy-Efficient Windows in Lockport Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.

Estimated Cost of Window Replacement in Lockport

Windows come in various shapes, styles and purposes, so costs and services will vary tremendously based on your project. Below, we describe the average cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs will differ significantly based on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $335 a year on your energy bills in Lockport.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you should get a full-frame or pocket installation.

Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. These installations are more involved and will increase the total cost. A pocket installation involves replacing a window within the old frame. So, instead of tearing out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Lockport, the choice will mostly be based on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Lockport

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Lockport and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. 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 super important review factor. If the majority of customers don’t have good things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. That’s why 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 been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Lockport, NY Window Replacement FAQs

How much does window installation cost?

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

Which type of window is the best?

A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I install my own windows?

Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on energy costs, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have only a few windows that are broken or drafty, you can replace just those.

How long does window installation usually take?

Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
