How Installing Energy-Efficient Windows in Damascus Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Better temperature control in your home: When you live in a city like Damascus where the winters can get very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
- Save money on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Damascus
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Typically, homeowners in Damascus can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. This is because window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Damascus home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, 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 cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a window installation is to clarify whether you need a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the frame that's already there. So, instead of removing the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you need.

How We Choose the Best Window Installers in Damascus
In our hunt to make your home improvements easier and more eco-friendly in Damascus, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Damascus, we gave more points to companies that cover 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 Damascus.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the most 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
Protecting your investment in new windows is important. That's why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Damascus, MD Window Replacement FAQs
How much should window installation cost?
The typical cost to install one window ranges between $450 and $650. There are a variety of factors that affect the price, such as local labor costs, your property's location, the number of windows, how energy-efficient the windows are, styles and sizes of windows and the materials used in designing the windows.
Which type of window should I get?
A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does window installation generally take?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
