How Installing Energy-Efficient Windows in Damascus Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
  • Save on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
  • Decrease your carbon footprint: In Damascus, you can reduce your indirect greenhouse gas emissions by about 249 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Damascus

Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Damascus can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which have a higher price tag.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Damascus homeowners $294+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using 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 offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant deterioration. These installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you’re still debating which type of installation you need, you can ask your provider and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Damascus

In our search to find the most reliable, eco-friendly window installers in Damascus, the EcoWatch Reviews team assessed many companies before deciding on these. We have evaluated the top window installation companies in Damascus primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Damascus, we only included companies that cover the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Damascus.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Damascus, MD Window Replacement FAQs

How much does window installation cost?

The typical cost to install one window can range from $450 to $650. There are many factors that influence the cost, which include styles and sizes of windows, the materials used in designing the windows, the number of windows, local labor costs, your property’s location and how energy-efficient the windows are.

What are the most common kinds of replacement windows?

The most common kinds of windows for homes are picture windows, double-hung and single-hung windows, slider windows, casement windows, transom windows, awning windows and bay windows.

When do I have to use a window installation company?

You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best handled by the professionals.

What time of year is the best time to replace my windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How do you know it’s time to replace your windows?

Windows typically last around 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them checked by an expert to determine if they are in need of a repair or replacement.
