How Installing Energy-Efficient Windows in Cortland Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to consider making the switch:
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Reduce your carbon footprint: In Cortland, you can reduce your indirect greenhouse gas emissions by about 65 pounds per year after you upgrade to energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Cortland
Windows come in various shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in Cortland can anticipate that most window installations will range from $250 to $1,200, with the average cost at around $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Cortland homeowners $418+ a year after replacing single-pane windows.
We recommend getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Full-frame installations are more involved and will raise the total cost. Pocket installations are on the simpler end and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company will be able to help you figure out what's best for your needs. In Cortland, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Cortland
In our search to make your home improvements easier and more eco-friendly in Cortland, the EcoWatch team evaluated dozens of companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Cortland, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Cortland.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of parts, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as 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. For that reason, window installation companies that give you 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Cortland, NY Window Replacement FAQs
What is the average cost to install new windows?
The typical cost of replacing a single window can range from $450 to $650. There are a variety of factors that affect the price, which include the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows, the number of windows, your property's location and local labor costs.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, including casement windows, bay windows, picture windows, slider windows, awning windows, transom windows and double-hung and single-hung windows.
Do you really need to use a window installation company?
You should hire a window installation company whenever you need to replace your windows. Installing windows is a complicated process that can take a lot of time, so it's best left to the professionals.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
