How Installing Energy-Efficient Windows in Lafayette Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $579 annually on your energy bills in Lafayette.
- Reduce your carbon footprint: In Lafayette, you can lower your indirect greenhouse gas emissions by about 117 pounds per year after you switch to energy-efficient windows.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Lafayette
When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, including material, type, size, the location of your home, number of windows and more.
It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Lafayette homeowners $579+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window installations, there are typically two types that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re not sure which window installation service you should get, your installer should be able to assist you. Typically, the decision is influenced by 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 Lafayette
In our search to find the most reliable, eco-friendly window installers in Lafayette, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Lafayette so you can find the best window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their service from 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 won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
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 from $200 to $1,200, depending 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, 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 types of windows?
The most common types of windows for homes are transom windows, slider windows, casement windows, double-hung and single-hung windows, bay windows, awning windows and picture windows.
What services do window replacement companies offer?
Window installers cover the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.
What time of year should I replace my windows?
Though you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn’t be raining, because rain can make the installation harder.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
