Lakewood Window Cost Calculator

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Lakewood Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:

  • Decrease your carbon footprint: In Lakewood, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
  • Better temperature control in your home: Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Lakewood

Let's go over the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Though the average to install a single window is about $600, it can range from $200 to $1,200. But costs will vary considerably based on your location, the current condition of your home, the number of windows you need and the quality of your products. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase overall project costs.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in Lakewood.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of an installation is to clarify whether you need a full-frame or pocket installation.

A full-frame installation replaces the total window, such as 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 (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you decide what's best for your needs. In Lakewood, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Lakewood

The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. We have decided to assess the top window installation companies in Lakewood mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, warranty, cost, quality of parts, professionalism and more.

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 gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Lakewood, CA Window Replacement FAQs

What is the typical cost to install windows?

The national average cost of replacing one 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 size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

Unless you have experience with home improvement projects and have all the tools you need 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 a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.

How long does it generally take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.

What time of year should I replace my windows?

Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
