How Installing Energy-Efficient Windows in Lancaster Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $368 a year on your bills.
  • Decrease 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.

Estimated Cost of Window Replacement in Lancaster

Windows come in different shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we describe the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Lancaster can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. These numbers are based on specific characteristics of your installation, such as the location of your home, material, size, number of windows, type and more.

Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $368 a year on your energy bills in Lancaster.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has considerable rot. Because these installations are more involved, they will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which window installation service you should get, your installer should be able to advise you. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lancaster

In our search to make your home improvements easier and more eco-friendly in Lancaster, EcoWatch landed on the above companies as the top window installation companies in the city. We’ve assessed the top window replacement companies in Lancaster mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Lancaster, we only included companies that serve the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Lancaster.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a sizable 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 labor rank higher with EcoWatch.

Years of Experience

Because of Lancaster’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lancaster window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Lancaster, NY Window Replacement FAQs

What is the typical cost to install new windows?

The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or experience, we don’t recommend doing it on your own.

Should I replace my windows all 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 typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
