How Installing Energy-Efficient Windows in Mill Valley Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Reduce your carbon footprint: In Mill Valley, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Mill Valley

When considering window installation, each company offers varying services and prices. Let's look at some average costs and services.

How Much Do New Windows Cost?

Typically, Mill Valley homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. But costs will vary considerably depending on the number of windows you need, the current condition of your home, the quality of your products and your location. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mill Valley homeowners $451+ per year after replacing single-pane windows.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without replacing the frame. So, instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Mill Valley, the decision 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 Mill Valley

In our hunt to make your home improvements easier and more eco-friendly in Mill Valley, the EcoWatch team examined dozens of companies before landing on these. We've evaluated the top window installers in Mill Valley mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Mill Valley, we only included companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Mill Valley.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable 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
