How Installing Energy-Efficient Windows in Annapolis Neck 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:

  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save $222 a year on your bills.
  • Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
  • Protect your investment: If your home is on the older side, 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.

Estimated Cost of Window Replacement in Annapolis Neck

Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you’ll find from window installers.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. Costs will differ significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

It’s important to remember that windows with the best 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 Annapolis Neck homeowners $222+ a year when replacing single-pane windows.

Another factor that affects the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services you can get: 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 professionals will replace the entire window, including the sill, trim and frame. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In Annapolis Neck, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Annapolis Neck

EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:

Service Area

Since this is a guide for Annapolis Neck, we only included companies that provide services to the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Annapolis Neck.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. 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 very important review factor. If the majority of customers don’t have nice things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Because of Annapolis Neck’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Annapolis Neck 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 Neck, MD Window Replacement FAQs

How much should window installation cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is often 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 initially but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

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

Do you really have to use a window installation company?

Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.

How long does it typically take to install windows?

Since a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.
