How Installing Energy-Efficient Windows in Pasadena Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Reduce 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.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Pasadena

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

Typically, homeowners in Pasadena can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. Costs will differ considerably based on the current condition of your home, your location, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

It’s important to bear in mind that windows with the best 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 Pasadena homeowners $222+ a year when replacing single-pane windows.

We advise getting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When considering window installations, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the complete window, including the trim, sill and frame. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window replacement company should be able to help you figure out what’s best for your needs. In Pasadena, 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 good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Pasadena

The EcoWatch Reviews team differs from other reviewers since we examine these companies through a sustainability lens. We have decided to assess the top window replacement companies in Pasadena primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Pasadena, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Pasadena.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher 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 determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, cost, warranty, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Pasadena, MD Window Replacement FAQs

What is the typical cost to replace windows in a home?

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

What are the most common types of replacement windows?

There are various types of windows you can get for your house, such as slider windows, transom windows, double-hung and single-hung windows, picture windows, awning windows, bay windows and casement windows.

Can I install my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is a good time to replace my windows?

While you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn’t be raining, as rain can make the installation harder.

Should I replace all my windows at once?

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