    How Installing Energy-Efficient Windows in Germantown Saves You Money

    By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:

    • Save on power bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $294 annually on your energy bills in Germantown.
    • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
    • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
    • Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 234 pounds per year on average.

    Estimated Cost of Window Replacement in Germantown

    Windows come in various shapes, styles and purposes, so costs and services will vary considerably based on several factors. Below, we go over the typical cost and services that you’ll find from window installers.

    How Much Do New Windows Cost?

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

    Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $294 a year on your energy bills in Germantown.

    Something else that influences the overall cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and light, 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 as well and cost somewhere between the other two.

    What Services do Window Installers Offer?

    Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

    Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

    Your window installation company should be able to help you decide what’s best for your needs. In Germantown, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

    How We Choose the Best Window Installers in Germantown

    In our hunt to find the most reliable, eco-friendly window installers in Germantown, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installers that serve Germantown so you can find the best window installation company near you.

    Work Quality

    We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

    Cost

    This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest 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 to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

    Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Germantown, MD Window Replacement FAQs

    What is the typical cost to replace windows in a home?

    The average cost to install a window ranges between $450 and $650. There are a variety of factors that affect how much it costs, such as your property’s location, local labor costs, the number of windows, styles and sizes of windows, the materials used in designing the windows and how energy-efficient the windows are.

    What are the most common kinds of replacement windows?

    There are several different kinds of windows you can get for your home, such as slider windows, awning windows, picture windows, casement windows, double-hung and single-hung windows, bay windows and transom windows.

    Can you install your own windows?

    If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or skills, we don’t recommend it.

    When is the best time of year to replace windows?

    While you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn’t be raining, because rain can make the installation harder.

    Should I replace all my windows at once?

    If you want to get more efficient windows and save money on energy costs, replacing all your windows together is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or drafty, you can replace just those.
