How Installing Energy-Efficient Windows in Annapolis Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 249 pounds.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in Annapolis
When looking into window installation, each company offers varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Annapolis homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Annapolis homeowners $222+ a year when replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the whole window, including the frame, trim and sill. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Annapolis, the decision will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Annapolis
EcoWatch is different from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Annapolis, we only included companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Annapolis.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
