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

When you switch to energy-efficient windows, you may see a few perks, including:

  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: In Foster City, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Foster City

When looking into window installation, each company provides varying services and prices. Let's go over some average costs and services.

How Much Do New Windows Cost?

Generally, Foster City homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost depends on several factors, such as material, the location of your home, number of windows, type, size and more.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Foster City, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Foster City

In our hunt to make your home improvements easier and more eco-friendly in Foster City, the EcoWatch team chose the above companies as the top window installation companies in the city. We have reviewed the top window installation companies in Foster City mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Foster City area so you can find the right window installation company near you.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, cost, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points 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 protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Foster City's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Foster City window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Foster City, CA Window Replacement FAQs

How much should a window install cost?

The national average cost of installing a single window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

While you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

How often should you replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
