How Installing Energy-Efficient Windows in Glendale Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Better temperature control in your home: When you reside in a city like Glendale where the winters can get chilly, you usually have to depend on your heater to keep your house warm. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Glendale
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range from $200 to $1,200. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Glendale homeowners $509+ per year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. 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 provide good insulation. Composite frames made with 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?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame 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.
If you're still debating which type of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Glendale
In our search to make your home improvements easier and more eco-friendly in Glendale, EcoWatch evaluated dozens of companies before deciding on these. We've assessed the top window installation companies in Glendale primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand 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 most important factor, as it indicates the quality of services across most other categories, including quality of installation, warranty, professionalism, cost, quality of parts and more.
Cost
Cheaper windows certainly don't 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Glendale's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Glendale window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Glendale, CA Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: awning windows, slider windows, picture windows, bay windows, casement windows, double-hung and single-hung windows and transom windows.
What do window installers do?
Window installers visit your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation more difficult.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
