How Installing Energy-Efficient Windows in Paramount Saves You Money
When you switch to energy-efficient windows, you may see some benefits, including:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: In Paramount, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Paramount
Windows come in varying purposes, shapes and styles, so costs and services will differ tremendously based on several factors. Below, we detail the typical cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
Generally, homeowners in Paramount can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These numbers vary based on specific characteristics of your installation, including the location of your home, type, size, number of windows, material and more.
It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Paramount homeowners $509+ a year when replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from 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?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the whole window, including the trim, frame and sill. Pocket installations are simpler and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you’re still trying to decide which kind of installation you should get, you can talk to your installer and get their advice. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Paramount
In our hunt to make your home improvements easier and more eco-friendly in Paramount, EcoWatch evaluated dozens of companies before landing on these. Along with energy efficiency, we assessed several window installers in Paramount and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Paramount so you can find the best window installation company near you.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
