How Installing Energy-Efficient Windows in Sierra Madre Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to consider making the switch:

  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save $571 a year on your bills.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • 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 fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Sierra Madre

Windows come in various styles, purposes and shapes, so costs and services will differ remarkably based on your project. Below, we describe the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Although the national average to replace a single window is about $600, it can range anywhere from $200 to $1,200. Costs will vary considerably depending on your location, the current condition of your home, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary based 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 a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When it comes to window replacements, there are typically two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're not sure which window installation service you need, your installer can help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Sierra Madre

The EcoWatch Reviews team is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

We're willing to bet 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 make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of 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 most other categories, including quality of installation, cost, quality of parts, warranty, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Sierra Madre, CA Window Replacement FAQs

How much should window installation cost?

The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

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

Can you install your own windows?

Even though 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 job is done properly and that you won't have to spend the time and effort to do it yourself.

How long does it usually take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, you most likely need 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.
