How Installing Energy-Efficient Windows in Mountain View Saves You Money

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

• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
• Better temperature control in your home: When you reside in a place like Mountain View where the winters can get chilly, you usually need to rely on your heater to keep your house warm. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
• Save money on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Mountain View

Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Mountain View can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. These amounts are based on the specifics of your installation, including number of windows, the location of your home, type, material, size and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mountain View homeowners $562+ each year after replacing single-pane windows.

Something else that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least expensive 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?

In regard to window installations, there are typically two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the frame that's already there. This means instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Mountain View, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Mountain View

EcoWatch is different from other reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Mountain View area so you can find the best window installation company near you.

Work Quality

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

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as 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. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
