How Installing Energy-Efficient Windows in Westminster Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save money on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Westminster, that’s about 460 pounds per year on average.
Estimated Cost of Window Replacement in Westminster
Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, like type, material, number of windows, the location of your home, size and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Westminster home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the full window, including the frame, sill and trim. A pocket installation involves replacing a window without removing the complete frame, which tends to be less expensive than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Westminster, the choice will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Westminster
EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. We have reviewed the best window replacement companies in Westminster mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because 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 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 company included on this list to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, professionalism, warranty, cost 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 providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

What is the average cost to replace windows in a home?
The national average cost of installing a window is about $600 but can range between $200 and $1,200, depending on several factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property.

Can you install your own windows?
If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. But if you don’t have the time or skills, we don’t recommend trying it.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
