How Installing Energy-Efficient Windows in Wellington 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:
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $522 annually on your energy bills in Wellington.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Wellington
Windows come in various purposes, styles and shapes, so costs and services will differ greatly based on your project. Below, we detail the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost you varies based on several factors, like the location of your home, number of windows, material, size, type and more.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Wellington home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Getting free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step of a window installation is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the sill, frame and trim. Pocket installations are simpler and won't cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Wellington, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Wellington
In our hunt to make your home improvements easier and more eco-friendly in Wellington, the EcoWatch team landed on the above companies as the best window installation companies in the city. We have decided to assess the top window installation companies in Wellington primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Wellington so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Wellington's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Wellington window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Wellington, CO Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
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 experience, we don't recommend doing it on your own.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
