How Installing Energy-Efficient Windows in Los Fresnos Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Los Fresnos, that's about 507 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Better temperature control in your home: Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Los Fresnos
Each window installer provides varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
Although the average to install one window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $402 a year on your energy bills in Los Fresnos.
Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Los Fresnos, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Los Fresnos
In our search to make your home improvements easier and more eco-friendly in Los Fresnos, the EcoWatch Reviews team evaluated many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Los Fresnos and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Los Fresnos, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Los Fresnos.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Los Fresnos' climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Los Fresnos window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Los Fresnos, TX Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind 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 typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
