How Installing Energy-Efficient Windows in Los Osos Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to think about making the switch:

  • Decrease your carbon footprint: In Los Osos, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Los Osos

Each window installation company provides various services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These figures vary based on the specifics of your installation, such as the location of your home, material, size, type, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Los Osos homeowners $521+ a year after replacing single-pane windows.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

If you're still trying to decide which kind of installation you need, you can ask your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Los Osos

In our search to make your home improvements easier and more eco-friendly in Los Osos, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you get. 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 customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a sizable 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

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Los Osos, CA Window Replacement FAQs

What is the average cost to install new windows?

The national average cost of installing a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, remember 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?

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

What services do window replacement companies provide?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How long does it take to install windows?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.

How do you know it's time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
