How Installing Energy-Efficient Windows in La Mesa Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- 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: Living in a chilly city like La Mesa usually means depending on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in La Mesa
Windows come in varying purposes, shapes and styles, so costs and services will differ greatly depending on several factors. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, homeowners in La Mesa can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at about $600. How much it will cost varies depending on several factors, including material, type, number of windows, the location of your home, size and more.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $491 a year on your energy bills in La Mesa.
Requesting free quotes from several companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When it comes to window replacements, there are typically two types that your installer will have: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable rot. Because full-frame installations are more involved, they will raise overall costs. Pocket installations are simpler and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in La Mesa
In our hunt to make your home improvements easier and more eco-friendly in La Mesa, the EcoWatch team chose the above companies as the top window installation companies in the city. We have evaluated the top window installation companies in La Mesa mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your 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 La Mesa, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in La Mesa.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. 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
Customer feedback is another super important review factor. If most customers don't have nice feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial 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 labor rank higher with EcoWatch.
Years of Experience
Due to La Mesa's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of La Mesa window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
La Mesa, CA Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to install one window ranges from $450 to $650. There are several factors that affect the price, which include the materials used in designing the windows, local labor costs, styles and sizes of windows, your property's location, the number of windows and how energy-efficient the windows are.
What are the types of windows?
There are various kinds of windows you can get for your home, such as bay windows, double-hung and single-hung windows, casement windows, slider windows, picture windows, transom windows and awning windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.
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 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.
Should I replace all my windows at once?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
