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

When you upgrade to energy-efficient windows, you may see a few benefits, including:

• Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Foster City, that’s about 117 pounds per year on average.
• Protect your investment: If you have an older home, 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 home if you decide to sell.

Estimated Cost of Window Replacement in Foster City

How Much Do New Windows Cost?

Generally, homeowners in Foster City can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost depends on several factors, including size, number of windows, the location of your home, type, material and more.

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

We advise requesting free quotes from multiple window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. These installations are more involved and will increase the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you’re not sure which type of window installation service you should get, your installer should be able to advise you. Generally, the decision is influenced by 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 Foster City

In our search to find the most reliable, eco-friendly window installers in Foster City, EcoWatch chose the above companies as the best window installation companies in the city. We’ve reviewed the top window replacement companies in Foster City primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Foster City, 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 Foster City.

Work Quality

When picking 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 opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try 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

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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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