How Installing Energy-Efficient Windows in Tustin Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on energy bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.

Estimated Cost of Window Replacement in Tustin

When researching window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will vary significantly depending on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $388 a year on your energy bills in Tustin.

Getting free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first step of a window installation is to think about whether you should get a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable deterioration. Because these installations are more involved, they will increase the overall cost. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Tustin

In our hunt to find the most reliable, eco-friendly window installers in Tustin, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and range 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 rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Tustin’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Tustin window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Tustin, CA Window Replacement FAQs

How much should window installation cost?

The average cost of replacing a single window ranges from $450 to $650. There are a variety of factors that affect how much it costs, which include your property’s location, the materials used in designing the windows, the number of windows, styles and sizes of windows, local labor costs and how energy-efficient the windows are.

What are the types of windows?

There are several different types of windows you can get for your home, including transom windows, double-hung and single-hung windows, bay windows, casement windows, slider windows, picture windows and awning windows.

Can you replace your own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
