How Installing Energy-Efficient Windows in Londonderry Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • 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 your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated.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 money on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Londonderry

Let's go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. These amounts are based on specific characteristics of your installation, including type, number of windows, the location of your home, size, material and more.

It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Londonderry home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the total window, including the frame, sill and trim. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Londonderry, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Londonderry

In our hunt to make your home improvements easier and more eco-friendly in Londonderry, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have evaluated the best window installers in Londonderry mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Londonderry, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Londonderry.

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 company included in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, quality of parts, quality of installation, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Londonderry, PA Window Replacement FAQs

How much should a window install cost?

The average cost of replacing one window ranges between $450 and $650. There are several factors that influence how much it costs, including styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property's location and local labor costs.

What are the different kinds of windows?

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

Can I install my own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend getting a professional to do it for you.

How long does window installation take?

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

Should I replace all my windows at the same time?

If you're upgrading your windows to get more efficient windows, replacing all of your windows together is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
