How Installing Energy-Efficient Windows in Westminster Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Save on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $388 annually on your energy bills in Westminster.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
- 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Westminster
Let's go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, Westminster homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at about $600. How much it will cost varies based on several factors, such as number of windows, material, the location of your home, type, size and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Westminster homeowners $388+ each year after replacing single-pane windows.
Requesting free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window without taking out the whole frame, which tends to be cheaper than a full-frame installation.
If you're not sure which kind of window installation service you need, your installer should be able to advise you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Westminster
EcoWatch is different from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Westminster and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
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 consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, quality of installation, professionalism, cost and more.
Cost
Cheaper windows certainly don't 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. 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 good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Westminster, CA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
