How Installing Energy-Efficient Windows in Brock Hall Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 249 pounds per year on average.
Estimated Cost of Window Replacement in Brock Hall
Windows come in varying purposes, shapes and styles, so costs and services will differ tremendously based on your project. Below, we describe the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These numbers vary depending on specific characteristics of your installation, such as number of windows, the location of your home, type, material, size and more.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in Brock Hall.
We advise requesting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step of a window replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you’re still trying to decide which kind of installation to get, you can talk to your provider and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Brock Hall
The EcoWatch Reviews team is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Brock Hall area so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of installation, quality of parts, professionalism, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. 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.
