How Installing Energy-Efficient Windows in Guilderland Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save money on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Guilderland, that's about 65 pounds per year on average.
Estimated Cost of Window Replacement in Guilderland
Let's go over the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $392 a year on your energy bills in Guilderland.
Another factor that influences the overall cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, 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?
In regard to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window without removing the whole frame, which is usually cheaper than a full-frame installation.
If you're still debating which kind of installation you should get, you can consult with your installer and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Guilderland
In our search to make your home improvements easier and more eco-friendly in Guilderland, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Guilderland, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Guilderland.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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.
Guilderland, NY Window Replacement FAQs
How much should window installation cost?
The typical cost of installing a window can range from $450 to $650. There are a variety of factors that affect how much it costs, including how energy-efficient the windows are, the number of windows, styles and sizes of windows, local labor costs, your property's location and the materials used in designing the windows.
What type of window is the most energy-efficient?
A window's energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals cover the entire process — from replacing your old windows with brand new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.
What time of year is the best time to replace my windows?
Though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation harder.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all of your windows at once is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or drafty, you can replace just those.
