How Installing Energy-Efficient Windows in Downingtown Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to make the switch:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help lower that number, which helps you save $304 a year on your bills.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Downingtown
When looking into window installation, each company offers varying services and prices. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Downingtown homeowners $304+ a year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire 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 rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Downingtown, the decision will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Downingtown
In our hunt to find the most reliable, eco-friendly window installers in Downingtown, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Downingtown area so you can find the best window installation company near you.
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 in our guide to ensure its technicians are well-qualified and that the company has gotten a lot 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 nice things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range 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 be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Downingtown's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Downingtown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Downingtown, PA Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are bay windows, picture windows, awning windows, double-hung and single-hung windows, slider windows, casement windows and transom windows.
Can I install my own windows?
Although you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
