How Installing Energy-Efficient Windows in Diamond Bar Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Decrease your carbon footprint: In Diamond Bar, you can cut your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
• Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.

Estimated Cost of Window Replacement in Diamond Bar

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ considerably based on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.

It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Diamond Bar home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you want for your window frames. 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 provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window within the frame that’s already there. So, instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you need, your installer can help you out. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Diamond Bar

EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We’ve decided to assess the top window installers in Diamond Bar mostly based on energy efficiency, 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 takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Diamond Bar area so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you get. 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 patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, cost, quality of installation, professionalism, 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 low when 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. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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