How Installing Energy-Efficient Windows in Lafayette Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • More efficient energy usage in your household: Because the winters can get very chilly in Lafayette, homeowners usually depend on their heater a lot. Energy-efficient windows decrease the amount of heat that is lost through your windows, making it easier to keep your home warm.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Lafayette

Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

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, but it depends if they are 100% 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?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the frame that's already there. So, instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Lafayette

The EcoWatch Reviews team is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Lafayette, we only included companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Lafayette.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, warranty, cost, quality of parts and more.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Lafayette, CA Window Replacement FAQs

What is the typical cost to install windows?

The average cost of installing a window can range between $450 and $650. There are many factors that affect the price, which include your property's location, the number of windows, how energy-efficient the windows are, local labor costs, the materials used in designing the windows and styles and sizes of windows.

What are the most common types of replacement windows?

The most common kinds of windows for homes include: slider windows, double-hung and single-hung windows, awning windows, picture windows, bay windows, transom windows and casement windows.

When should I use a window installation company?

You should use a window installation professional whenever you need new windows. Installing windows is a complex process that can take a lot of time, so it's best left to the professionals.

Should I replace my windows all at once?

If you're upgrading your windows to save on your energy bills, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
