How Installing Energy-Efficient Windows in Signal Hill Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Signal Hill
When researching window installation, each company offers varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Although the average cost of installing one window is about $600, it can range from $200 to $1,200. This is because of the fact that window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
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 replacing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a replacement is to decide whether you should get a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you’re still trying to decide which type of installation you should get, you can consult with your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Signal Hill
In our hunt to find the most reliable, eco-friendly window installers in Signal Hill, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We’ve decided to review the best window installation companies in Signal Hill primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Signal Hill, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Signal Hill.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you get. 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 very important review factor. If the majority of customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Signal Hill’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Signal Hill window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Signal Hill, CA Window Replacement FAQs
How much does window installation cost?
The typical cost of installing a single window ranges between $450 and $650. There are several factors that influence the cost, such as the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows, local labor costs and your property’s location.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
What time of year should I replace my windows?
While you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation more difficult.
