That's also bad for the environment, as the extra energy required by damaged windows increases your carbon footprint.
As windows are so important for your home, choosing the best company for you is a big choice to make. That's why the EcoWatch team has made this list of the best window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Twin Lakes Saves You Money
There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Save money on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Decrease your carbon footprint: In Twin Lakes, you can reduce your indirect greenhouse gas emissions by about 460 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Twin Lakes
Windows come in varying styles, shapes and purposes, so costs and services will vary remarkably based on several factors. Below, we describe the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will make your project cost more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more 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 won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you figure out what's best for your needs. In Twin Lakes, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Twin Lakes
The EcoWatch Reviews team is different from most reviewers because we look at these companies through a sustainability lens. We have evaluated the best window installation companies in Twin Lakes mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Twin Lakes, we paid more attention to companies that cover 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 Twin Lakes.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Twin Lakes' climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Twin Lakes window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Twin Lakes, CO Window Replacement FAQs
How much should a window install cost?
The average cost to replace a window can range from $450 to $650. There are many factors that affect how much it costs, which include local labor costs, your property's location, styles and sizes of windows, the number of windows, how energy-efficient the windows are and the materials used in designing the windows.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
Although it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does window installation generally take?
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.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
