How Installing Energy-Efficient Windows in Sterling Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:
- Decrease your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save around $320 annually on your energy bills in Sterling.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Sterling
When looking into window installation, each company offers varying services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Typically, Sterling homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost is based on several factors, like material, the location of your home, size, type, number of windows and more.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $320 a year on your energy bills in Sterling.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're still trying to decide which kind of installation you need, you can ask your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Sterling
In our hunt to make your home improvements easier and more eco-friendly in Sterling, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Sterling area so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, cost, quality of installation, warranty, professionalism and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Sterling's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Sterling window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Should I replace my windows all at the same time?
