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

There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

• Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $440 annually on your energy bills in Redwood City.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Redwood City

Each window replacement company offers varying services and has different costs depending on several factors.

How Much Do New Windows Cost?

Typically, Redwood City homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Redwood City homeowners $440+ per year after replacing single-pane windows.

Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from 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 provide decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window replacements, there are generally two types that your provider will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Redwood City, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Redwood City

EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends 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 indicates the quality of services across most other categories, including warranty, quality of installation, cost, quality of parts, professionalism and more.

Cost

Cheaper windows don’t necessarily 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

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
