How Installing Energy-Efficient Windows in Lewiston Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 65 pounds per year on average.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- 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.
Estimated Cost of Window Replacement in Lewiston
Windows come in varying shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Even though the average cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Lewiston home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you’re not sure which window installation service you should get, your installer can help you out. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lewiston
In our search to make your home improvements easier and more eco-friendly in Lewiston, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lewiston area so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers 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.
Lewiston, NY Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are various types of windows you can get for your house, such as casement windows, transom windows, slider windows, picture windows, bay windows, double-hung and single-hung windows and awning windows.
What do window installers do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often should you 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 damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
How long does it usually take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
