How Installing Energy-Efficient Windows in Lompoc Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Lompoc, that’s about 117 pounds per year on average.
- Save money on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Lompoc
When considering window installation, each company provides varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Lompoc homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at about $600. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.
It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Lompoc homeowners $482+ a year when replacing single-pane windows.
Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services you can get: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the frame, sill and trim. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Lompoc, 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 Lompoc
In our hunt to find the most reliable, eco-friendly window installers in Lompoc, the EcoWatch Reviews team examined many companies before deciding on these. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lompoc area so you can find a quality window installation company near you.
Work Quality
When it comes to 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 choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. Still, 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 sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Lompoc’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Lompoc window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lompoc, CA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing one window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually dependent on the location of your property, the size of the window and the type and material 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 kinds of windows?
The most common kinds of windows for homes include: awning windows, transom windows, casement windows, double-hung and single-hung windows, bay windows, picture windows and slider windows.
What services do window replacement companies do?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at once?
If you’re upgrading your windows to save on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
