How Installing Energy-Efficient Windows in Lancaster Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Save money on energy bills: After you install 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.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 65 pounds.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Lancaster
Let's go over the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Typically, Lancaster homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. 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 companies also offer door installations and replacements, which will add extra costs to your project.
It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Lancaster home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you pick for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer 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?
When it comes to window replacements, there are typically two kinds that your provider 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 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. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're still debating which type of installation you should get, you can ask your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Lancaster
EcoWatch reviews are different from most reviews, as we're examining these companies through a sustainability lens. We have evaluated the best window replacement companies in Lancaster mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lancaster, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Lancaster.
Work Quality
When choosing 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 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 customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers won't always provide the highest quality service. On the other hand, 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide 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 will earn higher rankings by our standards. We like to see at least ten years of experience.
Lancaster, NY Window Replacement FAQs
What is the typical cost to install windows in a home?
The typical cost to install a single window ranges between $450 and $650. There are a variety of factors that influence the price, such as the materials used in designing the windows, your property's location, styles and sizes of windows, how energy-efficient the windows are, the number of windows and local labor costs.
What are the different kinds of windows?
There are several different kinds of windows you can get for your home, including picture windows, slider windows, transom windows, casement windows, double-hung and single-hung windows, bay windows and awning windows.
What do window installation companies do?
Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn't be raining, because rain can make the installation harder.
How do you know it's time to replace your windows?
Windows typically have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
