Salisbury Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Salisbury, PA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Salisbury Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, including:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have an older home, your windows are most likely outdated.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 home if you decide to sell.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Salisbury

When researching window installation, each company offers different services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Though the average cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. But prices vary remarkably based 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 replacements, which will make your project cost more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Salisbury home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide 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?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the total window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re not sure which type of window installation service you should get, your installer can advise you. In general, the decision 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 Salisbury

In our hunt to find the most reliable, eco-friendly window installers in Salisbury, EcoWatch landed on the above companies as the best window installation companies in the city. We’ve assessed the best window replacement companies in Salisbury mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is 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 right window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, 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, windows are a considerable investment, so you’ll want to be certain 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

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

Salisbury, PA Window Replacement FAQs

What is the average cost to replace windows?

The national average cost to replace a window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars 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 will be 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 attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you’re handy and have all the tools you need to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.

How long does window installation usually take?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
