Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. Potential leaks or drafts from your windows can make your AC or heater work extra hard in the summer or winter.
That's also bad news for the environment, as the additional energy required by leaky windows increases your carbon footprint.
As windows have such a great impact on your home, selecting the right company for you is a big decision to make. That's why the EcoWatch team has made this list of the best window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Lafayette Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:
- Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $579 annually on your energy bills in Lafayette.
Estimated Cost of Window Replacement in Lafayette
Let's go over the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Generally, homeowners in Lafayette can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. How much it will cost you varies based on several factors, like material, number of windows, the location of your home, size, type and more.
With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lafayette homeowners $579+ per year after replacing single-pane windows.
Getting free quotes from several installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Lafayette, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Lafayette
The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We've evaluated the top window installation companies in Lafayette mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to 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 the Lafayette area so you can find the best window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, warranty, cost, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, 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 to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Lafayette's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Lafayette window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lafayette, CA Window Replacement FAQs
How much does window installation cost?
The national average cost to install a window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. However, if you don't have the time or experience, we recommend getting a professional to do it for you.
How long does window installation generally take?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn't be raining, because rain can make the installation harder.
