Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could be responsible for around 30% of heating and cooling costs. In Lake Forest, where the power bills are an average of $27 per month, that's almost $$97 per year wasted.

Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you money and helping the environment.

Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

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

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

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Lake Forest

When researching window installation, each company provides different services and prices. Let's look at some average costs and services.

How Much Do New Windows Cost?

Although the typical of installing a single window is around $600, it can range anywhere from $200 to $1,200. These numbers vary based on specific characteristics of your installation, like size, type, the location of your home, material, number of windows and more.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $388 a year on your energy bills in Lake Forest.

Something else that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window replacements, there are generally two types that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

If you're still debating which kind of installation you should get, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Lake Forest

In our hunt to make your home improvements easier and more eco-friendly in Lake Forest, EcoWatch chose the above companies as the best window installation companies in the city. We've decided to assess the best window installation companies in Lake Forest mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Lake Forest, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Lake Forest.

Work Quality

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

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Lake Forest, CA Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to replace a window is around $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which kind of window should I get?

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

What services do window installation companies offer?

Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.

How often should you replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
