How Installing Energy-Efficient Windows in Brighton Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, including:
- Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 460 pounds.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in Brighton
When researching window installation, each company provides different services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Brighton homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ significantly depending on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $455 a year on your energy bills in Brighton.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Brighton
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
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 type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent 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 nearly every category, including professionalism, quality of parts, quality of installation, warranty, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Brighton’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Brighton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Brighton, CO Window Replacement FAQs
How much should window installation cost?
The average cost of installing one window can range from $450 to $650. There are many factors that influence the cost, which include your property’s location, the number of windows, styles and sizes of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.
What are the most common types of replacement windows?
The most common kinds of windows for homes are slider windows, casement windows, picture windows, awning windows, bay windows, double-hung and single-hung windows and transom windows.
What services do window installation companies offer?
Window installers go to your house to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
