How Installing Energy-Efficient Windows in Boulder Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Protect your investment: If your home is on the older side, 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 house if you decide to sell.
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- 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 Boulder
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Generally, homeowners in Boulder can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost depends on several factors, including number of windows, size, the location of your home, type, material and more.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Boulder homeowners $457+ a year after replacing single-pane windows.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the full window, including the trim, frame and sill. 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 type of installment if you have any pre-existing rot or water damage.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Boulder, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.
