How Installing Energy-Efficient Windows in Londonderry Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

  • Better temperature control in your home: Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • More efficient energy use in your household: In Londonderry where the summers can get quite hot, energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
  • Reduce your carbon footprint: In Londonderry, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year once you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Londonderry

When looking into window installation, each company provides different services and costs. Let's take a look at some average costs and services.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost you varies based on several factors, like size, number of windows, material, type, the location of your home and more.

It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Londonderry homeowners $313+ a year when replacing single-pane windows.

Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with 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 provide decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing 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 still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

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 examined many companies before deciding on these. Along with energy efficiency, we assessed several window installers in Londonderry and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Londonderry so you can find a quality 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 in our guide to make sure its contractors are well-qualified and that the company has received a lot 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, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to other 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 variety 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 be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Londonderry, PA Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. 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.

What kind of window is the most energy-efficient?

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

Can you install your own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
