How Installing Energy-Efficient Windows in San Dimas Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to think about making the switch:
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in San Dimas
Each window installer offers various services and has different price points depending on a few factors.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost you is based on several factors, like type, material, size, number of windows, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your San Dimas home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else 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 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: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are simpler and won't cost as much because they entail 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.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in San Dimas
In our hunt to make your home improvements easier and more eco-friendly in San Dimas, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have decided to review the best window installers in San Dimas primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to San Dimas' climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of San Dimas window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
San Dimas, CA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on 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 initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
There are various kinds of windows you can get for your home, such as double-hung and single-hung windows, awning windows, bay windows, slider windows, casement windows, picture windows and transom windows.
When should I use a window installation company?
You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation usually take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace my windows all 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 usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
