How Installing Energy-Efficient Windows in Chillum Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few 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- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Better temperature control in your home: Energy-efficient windows can decrease how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Chillum
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Chillum can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary based on the specifics of your installation, like the location of your home, type, number of windows, size, material and more.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends if 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?
The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Chillum, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Chillum
EcoWatch reviews differ from most reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Chillum and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Chillum, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Chillum.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, warranty, cost, quality of parts, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Chillum's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Chillum window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Chillum, MD Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. 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 are the most common types of replacement windows?
The most common types of windows for homes are double-hung and single-hung windows, picture windows, transom windows, awning windows, slider windows, casement windows and bay windows.
When do I need 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 one 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 option.
What time of year is a good 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 your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
