How Installing Energy-Efficient Windows in Woodstock Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

• Reduce your carbon footprint: In Woodstock, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year after you upgrade to energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Woodstock

Each window installer offers varying services and has varying price points based on a few factors.

How Much Do New Windows Cost?

Even though the typical cost to replace one window is about $600, it can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Woodstock home can mean an average energy savings of $236 to $319 each 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 upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that affects the overall cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as 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?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the sill, frame and trim. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window replacement company should be able to help you figure out what’s best for your needs. In Woodstock, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Woodstock

In our search to make your home improvements easier and more eco-friendly in Woodstock, the EcoWatch team examined dozens of companies before landing on these. We’ve assessed the best window installation companies in Woodstock mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Woodstock, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Woodstock.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. 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 awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that provide 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 a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
