How Installing Energy-Efficient Windows in South Londonderry Saves You Money

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

  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save money on electricity 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 home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in South Londonderry

Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the typical costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. Costs will differ considerably depending on the current condition of your home, the quality of your products, the number of windows you need and your location. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your South Londonderry home translates to 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. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We advise requesting free quotes from multiple window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step when considering a window replacement is to figure out whether you want a full-frame or pocket installation.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in South Londonderry

In our hunt to find the most reliable, eco-friendly window installers in South Londonderry, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed several window installers in South Londonderry and ranked them using the following methodology:

Service Area

Because this is a guide for South Londonderry, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in South Londonderry.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Because of South Londonderry's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of South Londonderry window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

South Londonderry, PA Window Replacement FAQs

How much should a window install cost?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the kinds of windows?

The most common kinds of windows for homes include: awning windows, casement windows, transom windows, picture windows, slider windows, bay windows and double-hung and single-hung windows.

Do you really need to use a window installation company?

You should hire a window installation company whenever you want to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter 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 isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
