How Installing Energy-Efficient Windows in Patterson Saves You Money

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

  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: In Patterson, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
  • 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.

Estimated Cost of Window Replacement in Patterson

Windows come in varying purposes, styles and shapes, so costs and services will differ tremendously based on your project. Below, we detail the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Although the average cost to install one window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, such as material, type, the location of your home, number of windows, size and more.

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 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

We recommend getting free quotes from several window companies to find the one that works best for you.

What Services do Window Installers Offer?

When considering window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. 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, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Patterson

EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Patterson and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Patterson area so you can find the right window installation company near you.

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 in our guide to make sure its technicians are well-qualified and that the company has gotten tons 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 factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Patterson, CA Window Replacement FAQs

What is the average cost to install windows?

The average cost of replacing a window can range between $450 and $650. There are several factors that influence how much it costs, which include how energy-efficient the windows are, the number of windows, your property’s location, styles and sizes of windows, the materials used in designing the windows and local labor costs.

What type of window is the most energy-efficient?

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 typically the most energy-efficient and are certified by the U.S. Department of Energy.

When should I use a window installation company?

Unless you have experience with home improvement projects and have all the necessary tools to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

How do you know it’s time to replace your windows?

Windows generally last 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
