A guide on the top window installation companies in Marina may not seem like the most compelling article on EcoWatch, but trust us, windows have a more direct impact on your life than you might realize. Traditional or damaged windows can cost you in electricity bills. In fact, the Department of Energy estimates that about 30% of your home's heat or cool air could be lost through your windows.

Replacement windows improve your home's insulation, not only making you more comfortable during the summer and winter, but also saving you money and helping the environment.

Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Marina Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • 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. Switching to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
  • 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.

Estimated Cost of Window Replacement in Marina

Each window installer offers various services and has varying price points based on several factors.

How Much Do New Windows Cost?

Typically, Marina homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. But costs will vary considerably depending on your location, the number of windows you need, 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 coating, shutters, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Marina homeowners $515+ per year after replacing single-pane windows.

We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies provide: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

If you're still debating which type of installation you need, you can ask your provider and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Marina

In our search to make your home improvements easier and more eco-friendly in Marina, EcoWatch examined many companies before settling on these. We've assessed the best window installers in Marina mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Marina, 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 Marina.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. 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 trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave 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 labor rank higher with EcoWatch.

Years of Experience

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

Marina, CA Window Replacement FAQs

How much does window installation cost?

The typical cost to replace a window can range between $450 and $650. There are many factors that influence the cost, such as styles and sizes of windows, the materials used in designing the windows, the number of windows, local labor costs, your property's location and how energy-efficient the windows are.

Which type of window is the best?

A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.

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

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to 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 my windows all at once?

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