Why you can trust EcoWatch
The EcoWatch Reviews team is all about finding solutions for eco-conscious homeowners in Northampton. If your windows are made of traditional materials, or are outdated or damaged, you could be losing 25-30% of your house's heat or cool air out of them.
That's also bad news for the environment, as the additional energy required by outdated windows increases your carbon footprint.
Efficient windows are of particular importance in Northampton, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $312 each year.

How Installing Energy-Efficient Windows in Northampton Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 286 pounds.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save money on electricity bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save about $312 annually on your energy bills in Northampton.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Northampton
When researching window installation, each company provides varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. These estimates vary based on specific characteristics of your installation, like type, the location of your home, material, size, number of windows and more.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in Northampton.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails replacing a window without taking out the entire frame, which is usually less expensive than a full-frame installation.
If you're still trying to decide which type of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Northampton
In our hunt to make your home improvements easier and more eco-friendly in Northampton, EcoWatch examined dozens of companies before landing on these. Along with energy efficiency, we analyzed several window installers in Northampton and assigned rankings using the following methodology:
Service Area
Since this is a guide for Northampton, we gave more points to companies that provide services to 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 Northampton.
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 featured in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, 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 provide 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 been in the industry for a while. 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.
Northampton, PA Window Replacement FAQs
How much does a window install cost?
The average cost to install one window can range from $450 to $650. There are several factors that affect how much it costs, including styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property's location, the materials used in designing the windows and local labor costs.
What are the kinds of windows?
The most common types of windows for homes are double-hung and single-hung windows, casement windows, bay windows, awning windows, slider windows, picture windows and transom windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
How long does it typically take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How do you know it's time to replace your windows?
Windows generally have a lifespan of 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 are in need of a repair or replacement.
