How Installing Energy-Efficient Windows in West Lampeter Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:

  • Save on electricity bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $281 annually on your energy bills in West Lampeter.
  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
  • Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in West Lampeter

Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

Typically, homeowners in West Lampeter can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $281 a year on your energy bills in West Lampeter.

Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations are simpler and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you're still debating which kind of installation you should get, you can talk to your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in West Lampeter

EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain installer, it won't be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

West Lampeter, PA Window Replacement FAQs

What is the average cost to install new windows?

The typical cost to install a window can range from $450 to $650. There are many factors that affect the price, such as local labor costs, how energy-efficient the windows are, your property's location, styles and sizes of windows, the materials used in designing the windows and the number of windows.

Which type of window is the best?

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

When do I have to use a window installation company?

Unless you're handy and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.

How do you know it's time to replace your windows?

Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to see if they are in need of a repair or replacement.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
