How Installing Energy-Efficient Windows in Guilford Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Guilford

Each window installation company offers varying services and has varying price points based on several factors.

How Much Do New Windows Cost?

Although the average cost to replace one window is about $600, it can range anywhere from $200 to $1,200. But costs will vary considerably depending on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.

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

Asking for free quotes from multiple installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you’re still trying to decide which kind of installation you should get, you can ask your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Guilford

EcoWatch reviews are different from other reviews because we assess these companies through a sustainability lens. We have decided to evaluate the best window installation companies in Guilford mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Guilford area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when 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 previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Guilford, PA Window Replacement FAQs

How much does a window install cost?

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

Which type of window is the best?

A window’s energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you’re handy and have the time needed to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.

How often should you replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.

Should I replace my windows all at the same time?

If you’re upgrading your windows to save on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
