How Installing Energy-Efficient Windows in Ashland Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, such as:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower 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 damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Ashland
Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Typically, Ashland homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at around $600. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.
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 per year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Asking for 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?
The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the whole window, including the sill, trim and frame. Pocket installations are simpler 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 deterioration, you may need a full-frame installation instead.
If you’re not sure which kind of window installation service you need, your installer can help you out. Typically, the decision is based on 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 Ashland
In our search to find the most reliable, eco-friendly window installers in Ashland, the EcoWatch team examined many companies before deciding on these. We have assessed the top window installers in Ashland 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 power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Ashland, we only included companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Ashland.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher 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 highest rates of 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, quality of installation, professionalism, warranty, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Ashland’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Ashland window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Ashland, CA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
There are various types of windows you can get for your house, including slider windows, awning windows, double-hung and single-hung windows, casement windows, picture windows, transom windows and bay windows.
When do I need to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
