How Installing Energy-Efficient Windows in Lancaster Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on electricity bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Lancaster

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

How Much Do New Windows Cost?

Typically, Lancaster homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is 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 installers also provide door replacements, which will add extra costs to your project.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lancaster homeowners $387+ per year after replacing single-pane windows.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the whole 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 damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Lancaster

EcoWatch differs from most reviewers, as we're examining these companies through a sustainability lens. We have decided to review the top window installers in Lancaster mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When choosing 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 more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of installation, warranty, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. Still, 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

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Lancaster's climate, homeowners will want to mitigate water damage, low efficiency and rot. 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.
