How Installing Energy-Efficient Windows in Westtown Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, including:
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Westtown, that’s about 286 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Westtown
When looking into window installation, each company offers varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Even though the average cost to replace one window is around $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that upgrading the windows on your Westtown home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window installation is to think about whether you want a full-frame or pocket installation.
Full-frame installations require replacing the whole 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 damage. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which kind of window installation service you should get, your installer can help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Westtown
In our hunt to make your home improvements easier and more eco-friendly in Westtown, the EcoWatch team assessed dozens of companies before settling on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Westtown so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, cost, warranty, professionalism and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave 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 be certain that investment is well protected. 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 good 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.
