How Installing Energy-Efficient Windows in Randallstown Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, including:
- Better temperature control in your home: When you reside in a place like Randallstown where the winters can be very cold, you usually need to depend on your heater to keep your home warm. Energy-efficient windows can decrease how hard your heater needs to work to heat your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Randallstown
When considering window installation, each company provides varying services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Although the national average of replacing one window is about $600, it can range from $200 to $1,200. How much it will cost you varies based on several factors, such as the location of your home, material, type, size, number of windows and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Randallstown homeowners $285+ per year after replacing single-pane windows.
Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable rot. Full-frame installations are more involved and will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still debating which kind of installation you need, you can ask your installer and get their advice. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Randallstown
In our hunt to make your home improvements easier and more eco-friendly in Randallstown, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in 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 service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. Still, 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
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Randallstown's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Randallstown window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Randallstown, MD Window Replacement FAQs
How much does a window install cost?
The average cost of installing a single window ranges between $450 and $650. There are several factors that influence the cost, including how energy-efficient the windows are, the number of windows, your property's location, styles and sizes of windows, the materials used in designing the windows and local labor costs.
Which kind of window should I get?
A window's energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation companies will do the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.
What time of year should I replace my 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 make sure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
How often should you replace your windows?
Windows usually last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
