How Installing Energy-Efficient Windows in Pittsburg Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $579 annually on your energy bills in Pittsburg.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.

Estimated Cost of Window Replacement in Pittsburg

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

How Much Do New Windows Cost?

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

It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Pittsburg homeowners $579+ a year when replacing single-pane windows.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are typically 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?

In regard to window replacements, there are generally two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you're unsure which window installation service you should get, your installer can help you out. Typically, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Pittsburg

The EcoWatch Reviews team differs from other reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Pittsburg and assigned rankings using the following methodology:

Service Area

Because this is a guide for Pittsburg, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Pittsburg.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find 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 most other categories, including warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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

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

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Pittsburg, CA Window Replacement FAQs

How much does a window install cost?

The typical cost of replacing one window ranges from $450 to $650. There are many factors that affect the cost, such as how energy-efficient the windows are, the number of windows, styles and sizes of windows, your property's location, the materials used in designing the windows and local labor costs.

What are the most common types of replacement windows?

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

Can you install your own windows?

If you're handy and have experience with installing a replacement window, it's possible 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 often do you need to replace windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them looked at by an expert to determine if they are in need of a repair or replacement.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
