How Installing Energy-Efficient Windows in San Lorenzo Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Save money on energy bills: Once you switch 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 home.
  • Decrease your carbon footprint: In San Lorenzo, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you install energy-efficient windows.

Estimated Cost of Window Replacement in San Lorenzo

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

Although the average cost of replacing a single window is about $600, it can range from $200 to $1,200. Costs will differ considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Getting free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

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 extra materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you’re still trying to decide which type of installation you should get, you can ask your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in San Lorenzo

EcoWatch reviews differ from most reviews because we look at these companies through a sustainability lens. We’ve decided to review the best window installers in San Lorenzo mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including warranty, professionalism, quality of parts, cost, quality of installation and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded 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 that give you 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

San Lorenzo, CA Window Replacement FAQs

How much should window installation cost?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

A window’s energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you install your own windows?

Although you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.

How long does window installation generally take?

Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
