Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

A review of the best window installation companies in South Lockport may not seem like the most captivating article on EcoWatch, but trust us, windows have a more direct impact on your life than you might think. If you have traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means spending more on power bills.

That's also bad news for the environment because the additional energy used by leaky windows increases your carbon footprint.

Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in South Lockport Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in South Lockport

Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Although the national average to replace a single window is about $600, it can range anywhere from $200 to $1,200. But costs will differ considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save South Lockport homeowners $335+ each year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in South Lockport

The EcoWatch Reviews team differs from other reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in South Lockport and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve South Lockport so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services can often play 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 consider 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 experience with a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, 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 installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

South Lockport, NY Window Replacement FAQs

What is the average cost to install windows?

The average cost of installing one window can range between $450 and $650. There are many factors that influence the price, which include local labor costs, how energy-efficient the windows are, the number of windows, the materials used in designing the windows, your property's location and styles and sizes of 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 the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.

Should I replace my windows all at once?

If you're upgrading your windows to save on your energy bills, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or drafty, you can replace just those.
