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

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in Lake Forest

When considering window installation, each company provides different services and costs. Let's take a look at some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Lake Forest can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary based on specific characteristics of your installation, such as size, type, number of windows, the location of your home, material and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly 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 $535+ per year after replacing single-pane windows.

Another factor 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 provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, such as the sill, 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 its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're not sure which type of window installation service you need, your installer should be able to advise you. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

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, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain installer, it won't be featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, 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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Lake Forest's climate, homeowners need to be wary of water damage, rot and low efficiency. 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 should a window install cost?

The typical cost to replace a single window can range from $450 to $650. There are many factors that influence how much it costs, which include the materials used in designing the windows, local labor costs, your property's location, styles and sizes of windows, how energy-efficient the windows are and the number of windows.

What are the most common kinds of replacement windows?

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

When do I have to use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The window installation process is complicated and can take anywhere from four to six hours for one 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.

How long does it take to install windows?

Since a window takes about 30 minutes to install, around 16 windows can be installed during a typical 8-hour work day.

Should I replace my windows all at once?
