How Installing Energy-Efficient Windows in Alamo Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
• Decrease your carbon footprint: In Alamo, you can cut your indirect greenhouse gas emissions by about 507 pounds per year once you install energy-efficient windows.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save $460 a year on your bills.

Estimated Cost of Window Replacement in Alamo

Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. But costs will differ significantly depending on the current condition of your home, the quality of your products, the number of windows you need and your location. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

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 $460 a year on your energy bills in Alamo.

Asking for free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total 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 involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window replacement company will be able to help you decide what’s best for your needs. In Alamo, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

We analyzed trends in recent online reviews to determine 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 most other categories, including professionalism, warranty, quality of parts, cost, quality of installation and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores 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 that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

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