How Installing Energy-Efficient Windows in Clayton Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Clayton

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

On average, Clayton homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Clayton homeowners $579+ per year after replacing single-pane windows.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, 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 won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Clayton, the decision will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Clayton

EcoWatch reviews differ from most reviews since we look at these companies through a sustainability lens. 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 pretty self-explanatory, but we've chosen to highlight window installation companies that serve Clayton so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in insulation 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

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of installation, cost, quality of parts, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Clayton, CA Window Replacement FAQs

What is the typical cost to install new windows in a home?

The typical cost of installing one window can range from $450 to $650. There are a variety of factors that affect the price, including the number of windows, your property's location, styles and sizes of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.

What are the different types of windows?

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

When should I use a window installation company?

Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional installer. 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 save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.

How long does it generally take to install windows?

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

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.
