How Installing Energy-Efficient Windows in Lake Forest Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: In Lake Forest, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Lake Forest

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

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lake Forest homeowners $388+ per year after replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. These installations are more involved and will raise the overall cost. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Lake Forest

In our hunt to find the most reliable, eco-friendly window installers in Lake Forest, EcoWatch chose the above companies as the best window installation companies in the city. We have reviewed the top window installers in Lake Forest primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Lake Forest, CA Window Replacement FAQs

How much does a window install cost?

The national average cost of installing a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is generally 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 initially but can save you a decent amount of money a year in energy bills.

What are the most common kinds of replacement windows?

There are various types of windows you can get for your home, such as transom windows, picture windows, bay windows, casement windows, awning windows, double-hung and single-hung windows and slider windows.

What services do window installation companies provide?

Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

Should I replace all my windows at once?

If your windows are more 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. Doing your windows all at once will involve less paperwork and less stress.

How long does window installation usually take?

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