How Installing Energy-Efficient Windows in Loveland Saves You Money
There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 460 pounds per year on average.
Estimated Cost of Window Replacement in Loveland
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. These estimates vary based on the specifics of your installation, including size, number of windows, material, the location of your home, type and more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Loveland homeowners $522+ a year after replacing single-pane windows.
We recommend requesting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're unsure which kind of window installation service you need, your installer can help you out. Generally, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Loveland
In our search to make your home improvements easier and more eco-friendly in Loveland, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Loveland, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Loveland.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Loveland, CO Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost to install one window can range from $450 to $650. There are a variety of factors that affect the price, such as how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, the number of windows, your property's location and local labor costs.
What kind of window is the most energy-efficient?
A window's energy efficiency is affected 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 and are certified by the U.S. Department of Energy.
Do you really have to use a window installation company?
You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
