How Installing Energy-Efficient Windows in Westminster Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $289 annually on your energy bills in Westminster.
- Reduce your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Westminster
Let's go over the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Typically, Westminster homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at around $600. But prices 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 installers also offer door replacements, which will add extra costs to your project.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Westminster homeowners $289+ a year when replacing single-pane windows.
We recommend requesting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Westminster, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Westminster
In our search to find the most reliable, eco-friendly window installers in Westminster, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Westminster, we only included companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Westminster.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty and more.
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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Westminster's climate, homeowners need to be wary of low efficiency, rot 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.
Westminster, MD Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window.

There are various kinds of windows you can get for your home, such as casement windows, double-hung and single-hung windows, bay windows, awning windows, slider windows, picture windows and transom windows.
Can I install my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or skills, we don't recommend doing it on your own.
How long does window installation typically take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is it time to replace your windows?
Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to see if they are in need of a repair or replacement.
