How Installing Energy-Efficient Windows in Rock Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $483 annually on your energy bills in Rock.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 715 pounds per year on average.
Estimated Cost of Window Replacement in Rock
Each window replacement company offers various services and has varying costs based on several factors.
How Much Do New Windows Cost?
On average, homeowners in Rock can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. How much it will cost you varies based on several factors, including size, material, the location of your home, number of windows, type and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that affects the overall cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when planning a window installation is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the entire window, including the sill, frame and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're not sure which window installation service you should get, your installer can advise you. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Rock
The EcoWatch Reviews team differs from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Rock and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good things to say about their service from a certain window installation company, 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 low when possible. When analyzing providers' prices, we gave higher scores 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 make sure that investment is protected. Window installation companies with 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Rock, WI Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on 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 are the most common kinds of replacement windows?
The most common kinds of windows for homes are casement windows, bay windows, awning windows, double-hung and single-hung windows, slider windows, picture windows and transom windows.
What services do window replacement companies provide?
Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
Should I replace all my windows at the same time?
If you're upgrading your windows to get more efficient windows, replacing all your windows at once is the only way to gain that benefit. However, if you have just one or two windows that are broken or leaky, you can replace just those.
