How Installing Energy-Efficient Windows in Westphalia Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- More efficient energy usage in your home: In Westphalia where the winters can be very cold, energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your home warm.
- Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Westphalia
Let's take a look at the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. These amounts are based on the specifics of your installation, like size, material, the location of your home, type, number of windows and more.
It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Westphalia homeowners $283+ a year when replacing single-pane windows.
Requesting free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're unsure which type of window installation service you need, your installer can advise you. Typically, the choice is influenced by 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 Westphalia
In our hunt to find the most reliable, eco-friendly window installers in Westphalia, the EcoWatch team examined dozens of companies before deciding on these. Along with energy efficiency, we assessed several window installers in Westphalia and ranked them based on the following methodology:
Service Area
Because this is a guide for Westphalia, we only included companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Westphalia.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good things to say about their service from a certain installer, 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 as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that offer 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 quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Westphalia, MD Window Replacement FAQs
How much should window installation cost?
The national average cost to install a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, remember 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 types of windows for homes include: awning windows, picture windows, double-hung and single-hung windows, transom windows, casement windows, bay windows and slider windows.
Do you really need to 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 installer. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
