How Installing Energy-Efficient Windows in Belvidere Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint 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 fading of your furniture, carpet and other valuables.
- 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.
- Save money on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $277 annually on your energy bills in Belvidere.
Estimated Cost of Window Replacement in Belvidere
Each window installation company offers varying services and has different costs depending on several factors.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200. But costs will differ considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Belvidere home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are generally 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?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. Because full-frame installations are more involved, they will raise the total cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you understand what's best for your needs. In Belvidere, the decision will mostly be based on how old your home is and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Belvidere
In our search to make your home improvements easier and more eco-friendly in Belvidere, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we reviewed several window installers in Belvidere and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Belvidere, we gave more points to companies that serve 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 Belvidere.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. 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 positive things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded 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 be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Belvidere, IL Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost to replace one window can range between $450 and $650. There are a variety of factors that influence how much it costs, including local labor costs, how energy-efficient the windows are, your property's location, the number of windows, styles and sizes of windows and the materials used in designing the windows.
Which type of window is the best?
A window's energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should use a window installation professional whenever you need new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.
When is it time to replace your windows?
Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to see if they need any repairs or replacements.
Should I replace all my windows at once?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
