How Installing Energy-Efficient Windows in La Mirada Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, including:

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

What Services do Window Installers Offer?

When it comes to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable deterioration. Because these installations are more involved, they will raise the total cost. Pocket installations are on the simpler end and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

Your window installation company should be able to help you understand what’s best for your needs. In La Mirada, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the La Mirada area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand 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 determine the companies with the most 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, warranty, cost, professionalism, quality of parts and more.

Cost

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

Years of Experience

Due to La Mirada’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of La Mirada window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
