How Installing Energy-Efficient Windows in Westminster Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Westminster
When researching window installation, each company provides varying services and prices. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
On average, Westminster homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will differ considerably based on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Westminster homeowners $639+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step when planning an installation is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the complete 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 (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which type of installation to get, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Westminster
In our hunt to find the most reliable, eco-friendly window installers in Westminster, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have assessed the best window installers in Westminster mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have nice feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores 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 a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
