    How Installing Energy-Efficient Windows in Pittsburg Saves You Money

    When you upgrade to energy-efficient windows, you may see several benefits, such as:

    • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save more on your bills.
    • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
    • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Pittsburg, that’s about 117 pounds per year on average.
    • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.

    Estimated Cost of Window Replacement in Pittsburg

    Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.

    How Much Do New Windows Cost?

    Typically, homeowners in Pittsburg can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

    It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Pittsburg homeowners $579+ a year when replacing single-pane windows.

    Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 typically two kinds of window replacement services: full-frame and pocket installations.

    A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

    If you’re unsure which type of window installation service you need, your installer can help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

    How We Choose the Best Window Installers in Pittsburg

    In our search to make your home improvements easier and more eco-friendly in Pittsburg, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

    Service Area

    Since this is a guide for Pittsburg, we only included companies that serve the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Pittsburg.

    Work Quality

    When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

    Warranty

    As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Due to Pittsburg’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Pittsburg window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

    Pittsburg, CA Window Replacement FAQs

    What is the typical cost to install new windows in a home?

    The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on several factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

    What are the most common kinds of replacement windows?

    The most common kinds of windows for homes include: transom windows, awning windows, double-hung and single-hung windows, bay windows, picture windows, casement windows and slider windows.

    Do you really need to use a window installation company?

    Unless you have home repair skills and have all the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.

    When is it time to replace your windows?

    Windows typically last about 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them checked by an expert to see if they are in need of a repair or replacement.
