Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a big impact on home energy conservation. If you have old or damaged windows, your HVAC system could be working extra hard to heat or cool your house. This means spending more on power bills.

That’s not great for either your bank account or the environment, but one of the best window installation companies can help with that.

Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Loveland Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Save money on electricity bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 460 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • 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 harmful UV rays.

Estimated Cost of Window Replacement in Loveland

Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the average costs and the primary services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, Loveland homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. How much it will cost varies depending on several factors, including material, number of windows, the location of your home, size, type and more.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Loveland home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We advise getting free quotes from several window installation companies to find the right windows and the company 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.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Loveland, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Loveland

The EcoWatch Reviews team is different from most reviewers, as we assess these companies through a sustainability lens. We have assessed the top window replacement companies in Loveland mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

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 the cut because of the low odds that they would serve the average homeowner in Loveland.

Work Quality

When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Loveland, CO Window Replacement FAQs

What is the typical cost to replace windows in a home?

The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

A window’s energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you replace your own windows?

If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or know-how, we don’t recommend it.

How do you know it’s time to replace your windows?

Windows typically last around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them looked at by an expert to see if they are in need of a repair or replacement.

How long does it usually take to install windows?

Each window takes around 30 minutes to install depending 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.
