How Installing Energy-Efficient Windows in Johnstown Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Save money on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Johnstown
Each window installation company offers varying services and has different costs based on several factors.
How Much Do New Windows Cost?
Even though the average of installing a single window is around $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, including material, size, number of windows, type, the location of your home and more.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Johnstown homeowners $419+ a year when replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has significant rot. Because full-frame installations are more involved, they will raise overall costs. Pocket installations are on the simpler end and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you're still trying to decide which type of installation you should get, you can ask your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Johnstown
EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Johnstown and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Johnstown so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have positive feedback about their experience with a certain window installation 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 try to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Johnstown's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Johnstown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Johnstown, NY Window Replacement FAQs
How much does a window install cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, remember 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 types of windows?
There are several different kinds of windows you can get for your house, such as casement windows, slider windows, picture windows, awning windows, bay windows, transom windows and double-hung and single-hung windows.
What do window installers do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does it typically take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, 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 the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
