How Installing Energy-Efficient Windows in Thorndale Saves You Money
When you switch to energy-efficient windows, you may see some benefits, such as:
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Thorndale
Windows come in varying styles, purposes and shapes, so costs and services will vary greatly depending on several factors. Below, we detail the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Thorndale homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost you varies depending on several factors, such as number of windows, size, type, the location of your home, material and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Thorndale homeowners $304+ a year after replacing single-pane windows.
We advise getting free quotes from several window installers 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 offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Thorndale
In our search to make your home improvements easier and more eco-friendly in Thorndale, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Thorndale and assigned rankings using the following methodology:
Service Area
Since this is a guide for Thorndale, we only included companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Thorndale.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten 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 customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that provide 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.
