How Installing Energy-Efficient Windows in Timonium Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:
- Save on power bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save around $285 annually on your energy bills in Timonium.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Timonium
When looking into window installation, each company provides varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. Costs will vary considerably based on the current condition of your home, the number of windows you need, your location and the quality of your products. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to decide whether you want a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Timonium
EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. We've decided to review the best window replacement companies in Timonium mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. 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 online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, cost, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Timonium, MD Window Replacement FAQs
How much should a window install cost?
The typical cost to replace a window can range from $450 to $650. There are many factors that affect how much it costs, including your property's location, styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.
Which type of window should I get?
A window's energy efficiency is affected by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really have to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
How long does it typically take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
