How Installing Energy-Efficient Windows in Annapolis Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: In Annapolis, you can cut your indirect greenhouse gas emissions by about 249 pounds per year once you install energy-efficient windows.
  • Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Annapolis

Let's take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in Annapolis can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. But costs differ remarkably depending 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 will add extra costs to your project.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that switching out the windows on your Annapolis home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although 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 step when considering a replacement is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

If you're not sure which window installation service you need, your installer can advise you. In general, the decision is based on 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 Annapolis

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We have reviewed the best window installers in Annapolis mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Annapolis, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Annapolis.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, quality of installation, warranty, quality of parts and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Annapolis' climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Annapolis window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Annapolis, MD Window Replacement FAQs

How much should a window install cost?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

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 make sure 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 my windows all at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
