How Installing Energy-Efficient Windows in Randallstown Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save on power bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $285 annually on your energy bills in Randallstown.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Randallstown, you can reduce your indirect greenhouse gas emissions by about 249 pounds per year when you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Randallstown

Windows come in different purposes, styles and shapes, so costs and services will differ considerably depending on several factors. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Generally, Randallstown homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $285 a year on your energy bills in Randallstown.

Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using 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 offer decent insulation for your home.

What Services do Window Installers Offer?

The first step when planning an installation is to decide whether you want a full-frame or pocket installation.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the full window, including the trim, sill and frame. A pocket installation entails replacing a window within the old frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Randallstown

EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

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

Work Quality

When choosing new windows, the quality and variety of services can often play 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

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded 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 that give you 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Randallstown, MD Window Replacement FAQs

How much should window installation cost?

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

What are the most common types of replacement windows?

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

What services do window installation companies do?

Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.

Should I replace my windows all at once?

If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
