20 Best Window Companies in Westminster, MD (2025 Reviews)

How Installing Energy-Efficient Windows in Westminster Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
• Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Westminster

Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

According to our market research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will make your project cost more.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Westminster homeowners $289+ a year when replacing single-pane windows.

Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In Westminster, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Westminster

EcoWatch is different from most reviewers since we evaluate these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Westminster primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Westminster, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Westminster.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum 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 protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Westminster’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Westminster window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
