How Installing Energy-Efficient Windows in San Dimas Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:
- 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- More efficient energy usage in your household: Because the winters can get very chilly in San Dimas, homeowners often depend on their heater a lot. Energy-efficient windows decrease how much heat is lost through your windows, making it easier to keep your home warm.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
Estimated Cost of Window Replacement in San Dimas
Each window replacement company offers varying services and has different costs depending on a few factors.
How Much Do New Windows Cost?
Generally, San Dimas homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. Costs will vary significantly depending on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.
It's important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save San Dimas homeowners $509+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When considering window installations, there are typically two types that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window without removing the entire frame, which is generally less expensive than a full-frame installation.
If you're not sure which type of window installation service you should get, your installer should be able to advise you. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in San Dimas
The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. We have decided to review the best window installation companies in San Dimas mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the San Dimas area so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of parts, quality of installation, cost, professionalism and more.
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 the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to San Dimas' climate, homeowners will want to mitigate water damage, rot and low efficiency. 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.
