How Installing Energy-Efficient Windows in Lancaster Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Reduce your carbon footprint: In Lancaster, you can lower your indirect greenhouse gas emissions by about 117 pounds per year once you install energy-efficient windows.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Save on power 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 lower that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Lancaster

Each window installation company offers varying services and has different costs depending on a few factors.

How Much Do New Windows Cost?

Though the national average to install a single window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Lancaster homeowners $509+ a year when replacing single-pane windows.

Another factor that affects the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, 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?

There are typically two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you figure out what's best for your needs. In Lancaster, the decision will mostly be based on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Lancaster

In our search to make your home improvements easier and more eco-friendly in Lancaster, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Lancaster, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Lancaster.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, quality of parts, professionalism, cost, warranty and more.

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 awarded 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 make sure that investment is well protected. Window installation companies with 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.

Lancaster, CA Window Replacement FAQs

What is the average cost to install windows in a home?

The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a variety of 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, keep in mind 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 is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

When do I need to use a window installation company?

Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

How long does it typically take to install windows?

Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.

When is the best time of year to replace 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 ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
