How Installing Energy-Efficient Windows in Lakeside Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- 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 harmful UV rays.
Estimated Cost of Window Replacement in Lakeside
Let’s go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Generally, homeowners in Lakeside can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. How much it will cost is based on several factors, like size, the location of your home, material, number of windows, type and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations involve replacing the entire 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 significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need 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 Lakeside, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Lakeside
In our search to find the most reliable, eco-friendly window installers in Lakeside, EcoWatch evaluated many companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is 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 willing to bet that you’re looking for professionals who 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 received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Lakeside’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Lakeside window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Lakeside, CA Window Replacement FAQs
How much does a window install cost?
The average cost to install one window can range between $450 and $650. There are many factors that affect the price, such as the number of windows, the materials used in designing the windows, your property’s location, local labor costs, how energy-efficient the windows are and styles and sizes of windows.
What are the different kinds of windows?
The most common types of windows for homes include: double-hung and single-hung windows, slider windows, bay windows, transom windows, picture windows, casement windows and awning windows.
Do I really need to use a window installation company?
Unless you’re handy and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, because rain can make the installation harder.
