How Installing Energy-Efficient Windows in Foster City Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, such as:

• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Reduce your carbon footprint: In Foster City, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Foster City

Windows come in various shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we describe the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Although the national average of replacing a single window is around $600, it can range anywhere from $200 to $1,200. Costs will differ considerably depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $440 a year on your energy bills in Foster City.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. 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 with 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?

In general, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your professionals will replace the complete window, including the frame, trim and sill. A pocket installation involves replacing a window within the frame that's already there. So, instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which kind of window installation service you need, your installer should be able to assist you. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

We have evaluated the best window installers in Foster City primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy 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 installers that serve Foster City so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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.
